	S.B. Potter, S. Chandra, N. Erasmus, M. Hlakola, R.P. Julie, H. Worters, C. van Gend SAAO, Observatory, South Africa
	The South African Astronomical Observatory (SAAO) has embarked on an ambitious initiative to upgrade its telescopes, instruments, and data analysis capabilities, facilitating their intelligent integration and seamless coordination. This endeavour aims not only to improve efficiency and agility but also to unlock exciting scientific possibilities within the realms of multi-messenger and time-domain astronomy. The program encompasses hardware enhancements enabling autonomous operations, complemented by the development of sophisticated software solutions. Intelligent algorithms have been meticulously crafted to promptly and autonomously respond to real-time alerts from telescopes worldwide and space-based observatories. Overseeing this sophisticated framework is the Observatory Control System, actively managing the observing queue in real-time. This presentation will provide a summary of the program’s notable achievements thus far, with a specific focus on the successful completion and full operational readiness of one of the SAAO telescopes.

MO1BCO02	ITER Controls Approaching One Million Integrated EPICS Process Variables	software, MMI, operation, network	6
	A. Wallander, B. Bauvir ITER Organization, St. Paul lez Durance, France
	The ITER Tokamak is currently being assembled in southern France. In parallel, the supporting systems have completed installation and are under commissioning or operation. Over the last couple of years the electrical distribution, building services, liquid & gas, cooling water, reactive power compensation and cryoplant have been integrated, adding up to close to one million process variables. Those systems are operated, or under commissioning, from a temporary main control room or local control rooms close to the equipment using an integrated infrastructure. The ITER control system is therefore in production. As the ITER procurement is 90% in-kind, a major challenge has been the integration of the various systems provided by suppliers from the ITER members. Standardization, CODAC Core System software distribution, training and coaching have all played a positive role. Nevertheless, the integration has been more difficult than foreseen and the central team has been forced to rework much of the delivered software. In this paper we report on the current status of the ITER integrated control system with emphasize on lessons learned from integration of in-kind contributions.

MO1BCO03	LCLS-II Accelerator Control System Status	EPICS, MMI, linac, undulator	12
	D. Rogind, S. Kwon SLAC, Menlo Park, California, USA
	Funding: US DOE The Linac Coherent Light Source complex at the SLAC National Accelerator Laboratory has been upgraded to add a new superconducting accelerator with beam rates up to 1MHz. Though the majority of the more than twenty accelerator control systems are based on LCLS designs, to accommodate the increase in repetition rate from 120Hz to 1MHz, many of the diagnostics and global control systems are upgraded to high performance platforms with standalone CPUs running linuxRT to host the EPICS based controls. With installation and checkouts for control systems completing in 2022, the phased approach to integration and commissioning recently completed with demonstration of the threshold key performance parameters and first light occurring in the Summer of 2023. This paper provides an overview of the LCLS-II accelerator control system architecture, upgrades, the multi-year installation, checkout, integration, commissioning, and lessons learned.

	Funding: Contract Number DE-AC02-98CH10886 with the auspices of the US Department of Energy Preparations are underway to build the Electron Ion Collider (EIC) once Relativistic Heavy Ion Collider (RHIC) beam operations are end in 2025, providing an enhanced probe into the building blocks of nuclear physics for decades into the future. With commissioning of the new facility in mind, Accelerator Controls will require modernization in order to keep up with recent improvements in the field as well as to match the fundamental requirements of the accelerators that will be constructed. We will describe the status of the Controls System architecture that has been developed and prototyped for EIC, as well as plans for future work. Major influences on the requirements will be discussed, including EIC Common Platform applications as well as our expectation that we’ll need to support a hybrid environment covering both the proprietary RHIC Accelerator Device Object (ADO) environment as well as EPICS.

MO2BCO02	Concept and Design of an Extensible Middle-Layer Application Framework for Accelerator Operations and Development	framework, FEL, laser, software	30
	M. Schütte, J. Georg, A. Grünhagen, H. Schlarb DESY, Hamburg, Germany
	Data collection and analysis are becoming increasingly vital not only for the experiments conducted with particle accelerators but also for their operation, maintenance, and development. Due to lack of feasible alternatives, experts regularly resort to writing task-specific scripts to perform actions such as (event triggered or temporary) data collection, system failure detection and recovery, and even simple high-level feedbacks. Often, these scripts are not shared and are deemed to have little reuse value, giving them a short lifetime and causing redundant work. We report on a modular Python framework for constructing middle-layer applications from a library of parameterized functionality blocks (modules) by writing a simple configuration file in a human-oriented format. This encourages the creation of maintainable and reusable modules while offering an increasingly powerful and flexible platform that has few requirements to the user. A core engine instantiates the modules according to the configuration file, collects the required data from the control system and distributes it to the individual module instances for processing. Additionally, a publisher-subscriber messaging system is provided for inter-module communication. We discuss architecture & design choices, current state and future goals of the framework as well as real use-case examples from the European XFEL.

MO2BCO03	Strategy and Tools to Test Software in the SKA Project: The CSP. LMC Case	software, TANGO, framework, software-component	34
	G. Marotta, C. Baffa, E. Giani INAF - OA Arcetri, Firenze, Italy G. Brajnik IDS, Udine, Italy M. Colciago, I. Novak Cosylab Switzerland, Brugg, Switzerland
	The Square Kilometre Array (SKA) Telescope will be one of the largest and most complex scientific instruments ever built. The development of a reliable software for monitoring and controlling its operations is critical to the success of the entire SKA project. The Local Monitoring and Control of the Central Signal Processor (CSP. LMC) is a software responsible for controlling a key subsystem of the telescope, i.e. the Central Signal Processor (CSP). The software is implemented as a "device" within the TANGO framework, written in Python. In this paper we describe a testing strategy that addresses some typical problems of such a large and complex instrument. It is a multi-level strategy, based on a combination of automated tests (unit/component/integration), in the context of CI/CD practices. Software is also tested against errors and anomalous conditions that can occur while the CSP. LMC is interacting with external subsystems, which can be simulated. The paper also discusses needs and solutions based on data mining test results. This allows us to obtain statistics of unexpected failures and to investigate their causes. Furthermore, a database containing test results supports discovery of interesting and unexpected patterns of behaviors of the tests based on correlations about different test-related events and data. This helps us to develop a deeper understanding of the code’s functioning and to find suitable solutions to minimize unexpected behaviors. In addition it can be used also to support reliability testing.

MO2BCO04	Applying Standardised Software Architectural Concepts to Design Robust and Adaptable PLC Solutions	PLC, software, interface, hardware	40
	S.T. Huynh, B. Baranasic, M. Bueno, L. Feltrin Zanellatto, T. Freyermuth, P. Gessler, N. Jardón Bueno, N. Mashayekh, J. Tolkiehn EuXFEL, Schenefeld, Germany
	Between evolving requirements, additional feature requests and urgent maintenance tasks, the Programmable Logic Controllers (PLC) at the European X-Ray Free Electron Laser Facility (EuXFEL) have become subjected to an array of demands. As the maintainability effort towards the existing systems peak, the requirement for a sustainable solution become an ever pressing concern. Ultimately, in order to provide a PLC code base which can easily be supported and adapted to, a reworking was required from the ground up in the form of a new suite of libraries and tools. Through this, it was possible to bring standardised software principals into PLC design and development, conjunctively offering an interface into the existing code base for ongoing support of legacy code. The set of libraries are developed by incorporating software engineering principles and design patterns in test driven development within a layered architecture. In defining clear interfaces across all the architectural layers - from hardware, to the software representation of hardware, and clusters of software devices, the complexity of PLC development decreases down into modular blocks of unit tested code. Regular tasks such as the addition of features, modifications or process control can easily be performed due to the adaptability, flexibility and modularity of the core PLC code base.

MO2BCO06	Embedded Controller Software Development Best Practices at the National Ignition Facility	embedded, software, hardware, interface	54
	V.K. Gopalan, A.I. Barnes, C.M. Estes, J.M. Fisher, V.J. Hernandez, P. Kale, A. Pao, P.K. Singh LLNL, Livermore, USA
	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. Software development practices such as continuous integration and continuous delivery (CI/CD) are widely adopted by the National Ignition Facility (NIF) which helps to automate the software development, build, test, and deployment processes. However, using CI/CD in an embedded controller project poses several challenges due to the limited computing resources such as processing power, memory capacity and storage availability in such systems. This paper will present how CI/CD best practices were tailored and used to develop and deploy software for one of the NIF Master Oscillator Room (MOR) embedded controllers, which is based on custom designed hardware consisting of a microcontroller and a variety of laser sensors and drivers. The approach included the use of automated testing frameworks, customized build scripts, simulation environments, and an optimized build and deployment pipeline, leading to quicker release cycles, improved quality assurance and quicker defect correction. The paper will also detail the challenges faced during the development and deployment phases and the strategies used to overcome them. The experience gained with this methodology on a pilot project demonstrated that using CI/CD in embedded controller projects can be challenging, yet feasible with the right tools and strategies, and has the potential to be scaled and applied to the vast number of embedded controllers in the NIF control system.

MO2BCO07	Continuous Integration and Debian Packaging for Rapidly Evolving Software	software, database, framework, interface	61
	A.W.C. Barker, J. Georg, M. Hierholzer, M. Killenberg, T. Kozak, D. Rothe, N. Shehzad, C. Willner DESY, Hamburg, Germany
	We describe our Jenkins-based continuous integration system and Debian packaging methods, and their application to the rapid development of the ChimeraTK framework. ChimeraTK is a C++ framework for control system applications and hardware access with a high level of abstraction and consists of more than 30 constantly changing interdependent libraries. Each component has its own release cycle for rapid development, yet API and ABI changes must be propagated to prevent problems in dependent libraries and over 60 applications. We present how we configured a Jenkins-based continuous integration system to detect problems quickly and systematically for the rapid development of ChimeraTK. The Debian packaging system is designed to ensure the compatibility of binary interfaces (ABI) and of development files (API). We present our approach using build scripts that allow the deployment of rapidly changing libraries and their dependent applications as Debian packages. These even permit applications to load runtime plugins that draw from the same core library, yet are compiled independently.

MO2AO02	A Beamline and Experiment Control System for the SLS 2.0	interface, experiment, data-acquisition, EPICS	71
	K. Wakonig, C. Appel, A. Ashton, S. Augustin, M. Holler, I. Usov, J. Wyzula, X. Yao PSI, Villigen PSI, Switzerland
	The beamlines of the Swiss Light Source (SLS) predominantly rely on EPICS standards as their control interface but in contrast to many other facilities, there is up to now no standardized user interfacing component to orchestrate, monitor and provide feedback on the data acquisition. As a result, the beamlines have either adapted community solutions or developed their own high-level orchestration system. For the upgrade project SLS 2.0, a sub-project was initiated to facilitate a unified beamline and experiment control system. During a pilot phase and a first development cycle, libraries of the Bluesky project were used, combined with additional in-house developed services, and embedded in a service-based approach with a message broker and in-memory database. Leveraging the community solutions paired with industry standards, enabled the development of a highly modular system which provides the flexibility needed for a constantly changing scientific environment. One year after the development started, the system was already tested during many weeks of user operation and recently received the official approval by the involved divisions to be rolled out as part of the SLS 2.0 upgrade.

MO2AO03	The Solid Sample Scanning Workflow at the European XFEL	target, FEL, experiment, database	78
	A. García-Tabarés Valdivieso, C. Deiter, L. Gelisio, S. Göde, S. Hauf, A.K. Kardoost, I. Karpics, J. Schulz, F. Sohn EuXFEL, Schelefeld, Germany
	The fast solid sample scanner (FSSS) used at the HED instrument of the European XFEL (EuXFEL) enables data collection from multiple samples mounted into standardized frames which can be exchanged via a transfer system without breaking the interaction chamber vacuum. In order to maximize the effective target shot repetition rate, it is a key requirement to use sample holders containing pre-aligned targets measured on an accurate level of a few micrometers. This contribution describes the automated sample delivery workflow for performing solid sample scanning using the FSSS. This workflow covers the entire process, from automatically identifying target positions within the sample, using machine learning algorithms, to set the parameters needed to perform the scans. The integration of this solution into the EuXFEL control system, Karabo, not only allows to control and perform the scans with the existing scan tool but also provides tools for image annotation and data acquisition. The solution thus enables the storage of data and metadata for future correlation across a variety of beamline parameters set during the experiment.

MO2AO04	Experimental Data Taking and Management: The Upgrade Process at BESSY II and HZB	experiment, EPICS, data-acquisition, MMI	84
	R. Müller, H. Görzig, G. Hartmann, K. Kiefer, R. Ovsyannikov, W. Smith, S. Vadilonga, J. Viefhaus HZB, Berlin, Germany D.B. Allan BNL, Upton, New York, USA
	The endeavor of modernizing science data acquisition at BESSY II started 2019 [] Significant achievements have been made: the Bluesky software ecosystem is now accepted framework for data acquisition, flow control and automation. It is operational at an increasing number of HZB beamlines, endstations and instruments. Participation in the global Bluesky collaboration is an extremely empowering experience. Promoting FAIR data principles at all levels developed a unifying momentum, providing guidance at less obvious design considerations. Now a joint demonstrator project of DESY, HZB, HZDR and KIT, named ROCK-IT (Remote Operando Controlled Knowledge-driven, IT-based), aims at portable solutions for fully automated measurements in the catalysis area of material science and is spearheading common developments. Foundation there is laid by Bluesky data acquisition, AI/ML support and analysis, modular sample environment, robotics and FAIR data handling. This paper puts present HZB controls projects as well as detailed HZB contributions to this conference [] into context. It outlines strategies providing appropriate digital tools at a successor 4th generation light source BESSY III. [] R.

MO2AO05	Deployment of ADTimePix3 areaDetector Driver at Neutron and X-ray User Facilities	detector, neutron, EPICS, software	90
	K.J. Gofron, J. Wlodek BNL, Upton, New York, USA S.C. Chong, F. Fumiaki, SG. Giles, G.S. Guyotte, SDL. Lyons ORNL, Oak Ridge, Tennessee, USA B. Vacaliuc ORNL RAD, Oak Ridge, Tennessee, USA
	Funding: This work was supported by the U.S. Department of Energy, Office of Science, Scientific User Facilities Division under Contract No. DE-AC05-00OR22725. TimePix3 is a 65k hybrid pixel readout chip with simultaneous Time-of-Arrival (ToA) and Time-over-Threshold (ToT) recording in each pixel. The chip operates without a trigger signal with a sparse readout where only pixels containing events are read out. The flexible architecture allows 40 MHits/s/cm² readout throughput, using simultaneous readout and acquisition by sharing readout logic with transport logic of superpixel matrix formed using 2x4 structure. The chip ToA records 1.5625 ns time resolution. The X-ray and charged particle events are counted directly. However, indirect neutron counts use 6Li fission in a scintillator matrix, such as ZnS(Ag). The fission space-charge region is limited to 5-9 um. A photon from scintillator material excites a photocathode electron, which is further multiplied in dual-stack MCP. The neutron count event is a cluster of electron events at the chip. We report on the EPICS areaDetector* ADTimePix3 driver that controls Serval*** using json commands. The driver directs data to storage and to a real-time processing pipeline and configures the chip. The time-stamped data are stored in raw .tpx3 file format and passed through a socket where the clustering software identifies individual neutron events. The conventional 2D images are available as images for each exposure frame, and a preview is useful for sample alignment. The areaDetector driver allows integration of time-enhanced capabilities of this detector into SNS beamlines controls and unprecedented time resolution.

MO2AO06	Neutron From a Distance: Remote Access to Experiments	experiment, GUI, network, software	95
	P. Mutti, F. Cecillon, C. Cocho, A. Elaazzouzi, Y. Le Goc, J. Locatelli, H. Ortiz ILL, Grenoble, France
	Large-scale experimental facilities such as the ILL are designed to accommodate thousands of international visitors each year. Despite the annual influx of visitors, there has always been interest in options that don’t require users to travel to ILL. Remote access to instruments and datasets would unlock scientific opportunities for those less able to travel and contribute to global challenges like pandemics and global warming. Remote access systems can also increase the efficiency of experiments. For measurements that last a long time scientists can check regularly on the progress of the data taking from a distance, adjusting the instrument remotely if needed. Based on the VISA platform, the remote access becomes a cloud-based application which requires only a web browser and an internet connection. NOMAD Remote provides the same experience for users at home as though they were carrying out their experiment at the facility. VISA makes it easy for the experimental team to collaborate by allowing users and instrument scientists to share the same environment in real time. NOMAD Remote, an extension of the ILL instrument control software, enables researchers to take control of all instruments with continued hands-on support from local experts. Developed in-house, NOMAD Remote is a ground-breaking advance in remote access to neutron techniques. It allows full control of the extensive range of experimental environments with the highest security standards for data, and access to the instrument is carefully prioritised and authenticated.

MO2AO07	Dynamical Modelling Validation and Control Development for the New High-Dynamic Double-Crystal Monochromator (HD-DCM-Lite) for Sirius/LNLS	FPGA, MMI, experiment, HOM	100
	T.R. Silva Soares, J.P.S. Furtado, R.R. Geraldes, M. Saveri Silva, G.S. de Albuquerque LNLS, Campinas, Brazil
	Two new High-Dynamic Double-Crystal Monochromators (HD-DCM-Lite) are under installation in Sirius/LNLS for the new beamlines QUATI (quick-EXAFS) and SAPUCAIA (SAXS), which requires high in-position stability (5 nrad RMS in terms of pitch) whereas QUATI’s DCM demands the ability to perform quick sinusoidal scans in frequencies, for example 15 Hz at 4 mrad peak-to-peak amplitude. Therefore, this equipment aims to figure as an unparalleled bridge between slow step-scan DCMs, and channel-cut quick-EXAFS monochromators. In the previous conference, the dynamical modelling of HD-DCM-Lite was presented, indicating the expected performance to achieve QUATI and SAPUCAIA requirements. In this work, we are going to present the offline validation of the dynamical modelling, comparing to the solutions achieved for the previous version of LNLS HD-DCMs. This work also presents the hardware-based control architecture development, discussing the loop shaping technique and upgrades in the system, such as the increase of the position resolution, synchronization of the rotary stages, and FPGA code optimization. Furthermore, we describe how the motion controller was developed, given the high-performance motion control, such as complex control algorithm in parallel with a minimal jitter and the expectations for the beamlines commissioning regarding detector and undulator synchronization.

MO3AO02	Implementation of Model Predictive Control for Slow Orbit Feedback Control in MAX IV Accelerators Using PyTango Framework	feedback, TANGO, operation, storage-ring	116
	C. Takahashi, J. Breunlin, A. Freitas, M. Sjöström MAX IV Laboratory, Lund University, Lund, Sweden P. Giselsson, E. Jensen Gassheld, M. Karlsson Lund University, Lund, Sweden
	Achieving low emittance and high brightness in modern light sources requires stable beams, which are commonly achieved through feedback solutions. The MAX IV light source has two feedback systems, Fast Orbit Feedback (FOFB) and Slow Orbit Feedback (SOFB), operating in overlapping frequency regions. Currently in MAX IV, a general feedback device implemented in PyTango is used for slow orbit and trajectory correction, but an MPC controller for the beam orbit has been proposed to improve system robustness. The controller uses iterative optimisation of the system model, current measurements, dynamic states and system constraints to calculate changes in the controlled variables. The new device implements the MPC model according to the beam orbit response matrix, subscribes to change events on all beam position attributes and updates the control signal given to the slow magnets with a 10 Hz rate. This project aims to improve system robustness and reduce actuator saturation. The use of PyTango simplifies the implementation of the MPC controller by allowing access to high-level optimisation and control packages. This project will contribute to the development of a high-quality feedback control system for MAX IV accelerators.

MO3AO03	Commissioning and Optimization of the SIRIUS Fast Orbit Feedback	feedback, power-supply, operation, network	123

	The Sirius Fast Orbit Feedback System (FOFB) entered operation for users in November 2022. The system design aimed at minimizing the overall feedback loop delay, understood as the main performance bottleneck in typical FOFB systems. Driven by this goal, the loop update rate was chosen as high as possible, real-time processing was entirely done in FPGAs, BPMs and corrector power supplies were tightly integrated to the feedback controllers in MicroTCA crates, a small number of BPMs was included in the feedback loop and a dedicated network engine was used. These choices targeted a disturbance rejection crossover frequency of 1 kHz. To deal with the DC currents that build up in the fast orbit corrector power supplies, a method to transfer the DC control effort to the Slow Orbit Feedback System (SOFB) running in parallel was implemented.

MO3AO04	Modelling and Control of a MeerKAT Antenna	target, experiment, site, factory	131
	I.A. Dodia SARAO, Cape Town, South Africa
	This paper presents a comprehensive approach to modeling for control system design for a MeerKAT antenna. It focuses on dynamic modeling using time and frequency domain techniques, and lays the foundation for the design of a control system to meet the telescope’s stringent pointing and tracking requirements. The paper scope includes rigid body modelling of the antenna, system identification to obtain model parameters, and building a system model in Simulink. The Simulink model allows us to compare model performance with the measured antenna pointing, under various environmental conditions. The paper also integrates models for pointing disturbances, such as wind and friction. The integrated model is compared to the existing control setup. Wind disturbance plays a significant role in the pointing performance of the antenna, therefore the focus is placed on developing an appropriate wind model. This research will conclude by providing a well-documented, systematic control system design that is owned by SARAO and can be implemented to improve the pointing performance of the telescope.

MO3AO05	Path to Ignition at National Ignition Facility (NIF): The Role of the Automated Alignment System	alignment, laser, target, operation	138
	B.P. Patel, A.A.S. Awwal, M. Fedorov, R.R. Leach Jr., R.R. Lowe-Webb, V.J. Miller Kamm, P.K. Singh LLNL, Livermore, California, USA
	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 The historical breakthrough experiment at the National Ignition Facility (NIF) produced fusion ignition in a laboratory for the first time and made headlines around the world. This achievement was the result of decades of research, thousands of people, and hardware and software systems that rivaled the complexity of anything built before. The NIF laser Automatic Alignment (AA) system has played a major role in this accomplishment. Each high yield shot in the NIF laser system requires all 192 laser beams to arrive at the target within 30 picoseconds and be aligned within 50 microns-half the diameter of human hair-all with the correct wavelength and energy. AA makes it possible to align and fire the 192 NIF laser beams efficiently and reliably several times a day. AA is built on multiple layers of complex calculations and algorithms that implement data and image analysis to position optical devices in the beam path in a highly accurate and repeatable manner through the controlled movement of about 66,000 control points. The system was designed to have minimum or no human intervention. This paper will describe AA’s evolution, its role in ignition, and future modernization. LLNL Release Number: LLNL-ABS-847783

MO3AO06	Energy Consumption Optimisation by Using Advanced Control Algorithms	operation, PLC, MMI, simulation	145
	F. Ghawash, E. Blanco Viñuela, B. Schofield CERN, Meyrin, Switzerland
	Large industries operate energy-intensive equipment and energy efficiency is an important objective when trying to optimize the final energy consumption. CERN utilizes a large amount of electrical energy to run its accelerators, detectors and test facilities, with a total yearly consumption of 1.3 TWh and peaks of about 200 MW. Final energy consumption reduction can be achieved by dedicated technical solutions and advanced automation technologies, especially those based on optimization algorithms, have revealed a crucial role not only in keeping the processes within required safety and operational conditions but also in incorporating financial factors. MBPC (Model-Based Predictive Control) is a feedback control algorithm which can naturally integrate the capability of achieving reduced energy consumption when including economic factors in the optimization formulation. This paper reports on the experience gathered when applying non-linear MBPC to some of the contributors to the electricity bill at CERN: the cooling and ventilation plants (i.e. cooling towers, chillers, and air handling units). Simulation results with cooling towers showed significant performance improvements and energy savings close to 20% over conventional heuristic solutions. The control problem formulation, the control strategy validation using a digital twin and the initial results in a real industrial plant are reported together with the experience gained implementing the algorithm in industrial controllers.

MO3AO07	Control Design Optimisations of Robots for the Maintenance and Inspection of Particle Accelerators	cavity, operation, interface, software	153
	A. Díaz Rosales, M. Di Castro, H. Gamper CERN, Meyrin, Switzerland
	Automated maintenance and inspection systems have become increasingly important over the last decade for the availability of the accelerators at CERN. This is mainly due to improvements in robotic perception, control and cognition and especially because of the rapid advancement in artificial intelligence. The robotic service at CERN performed the first interventions in 2014 with robotic solutions from external companies. However, it soon became clear that a customized platform needed to be developed in order to satisfy the needs and in order to efficiently navigate through the cluttered, semi-structured environment. This led to the formation of a robotic fleet of about 20 different robotic systems that are currently active at CERN. In order to increase the efficiency and robustness of robotic platforms for future accelerators it is necessary to consider robotic interventions at the early design phase of such machines. Task specific solutions tailored to the specific needs can then be designed, which in general show higher efficiency than multipurpose industrial robotic systems. This paper presents current advances in the design and development of task specific robotic system for maintenance and inspection in particle accelerators, taking the 100 km long Future Circular Collider main tunnel as a use case. The requirements on such a robotic system, including the applied control strategies, are shown, as well as the optimization of the topology and geometry of the robotic system itself.

	J.K. Abraham, H. Anderson iThemba LABS, Somerset West, South Africa W. Duckitt Stellenbosch University, Matieland, South Africa
	The South African Isotope Facility (SAIF) at iThemba LABS is well into its commissioning phase. The intention of SAIF is to free up our existing Separated Sector Cyclotron to do more physics research and to increase our radioisotope production and research capacity. An EPICS based control system, primarily utilising EtherCAT hardware, has been developed that spans the control of beamline equipment, target handling and bombardment stations, vault clearance and ARMS systems. Various building and peripheral services like cooling water and gases, HVAC and UPS have also been integrated into the control system via Modbus and OPCUA to allow for seamless control and monitoring. An overview of the SAIF facility and the EPICS based control system is presented. The control strategies, hardware and various EPICS and web based software and tools utilised are presented.

MO3BCO05	Online Models for X-ray Beamlines Using Sirepo-Bluesky	synchrotron, optics, radiation, electron	165
	J.A. Einstein-Curtis, D.T. Abell, M.V. Keilman, P. Moeller, B. Nash, I.V. Pogorelov RadiaSoft LLC, Boulder, Colorado, USA Y. Du, A. Giles, J. Lynch, T. Morris, M. Rakitin, A.L. Walter BNL, Upton, New York, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Science, under Award Number DE-SC0020593. Synchrotron radiation beamlines transport X-rays from the electron beam source to the experimental sample. Precise alignment of the beamline optics is required to achieve adequate beam properties at the sample. This process is often done manually and can be quite time consuming. Further, we would like to know the properties at the sample in order to provide metadata for X-ray experiments. Diagnostics may provide some of this information but important properties may remain unmeasured. In order to solve both of these problems, we are developing tools to create fast online models (also known as digital twins). For this purpose, we are creating reduced models that fit into a hierarchy of X-ray models of varying degrees of complexity and runtime. These are implemented within a software framework called Sirepo-Bluesky* that allows for the computation of the model from within a Bluesky session which may control a real beamline. This work is done in collaboration with NSLS-II. We present the status of the software development and beamline measurements including results from the TES beamline. Finally, we present an outlook for continuing this work and applying it to more beamlines at NSLS-II and other synchrotron facilities around the world. *https://github.com/NSLS-II/sirepo-bluesky

MO3BCO06	Web Technology Enabling Fast and Easy Implementation of Large Experimental Facility Control System	experiment, EPICS, framework, interface	171
	W. Zheng, H.B. Ma, L.Y. Wang, X.H. Xie, W.J. Ye, M. Zhang, P.L. Zhang HUST, Hubei, People’s Republic of China
	Funding: This work is supported by the National Magnetic Confinement Fusion Science Program (No. 2017YFE0301803) and by the National Natural Science Foundation of China (No.51821005). Large experimental facilities are essential for pushing the frontier of fundamental research. The control system is the key for smooth operation for Large experimental facilities. Recently many new types of facilities have emerged, especially in fusion community, new machines with completely different designs are being built. They are not as mature as accelerators. They need flexible control systems to accommodate frequent changes in hardware and experiment workflow. The ability to quickly integrate new device and sub-systems into the control system as well as to easily adopt new operation modes are important requirements for the control system. Here we present a control system framework that is built with standard web technology. The key is using HTTP RESTful web API as the fundamental protocol for maximum interoperability. This enables it to be integrated into the already well developed ecosystem of web technology. Many existing tools can be integrated with no or little development. for instance, InfluxDB can be used as the archiver, Node-RED can be used as the Scripter and Docker can be used for quick deployment. It has also made integration of in house developed embedded devices much easier. In this paper we will present the capability of this control system framework, as well as a control system for field-reversed configuration fusion experiment facility implemented with it.

MO3BCO07	Fast Beam Delivery for Flash Irradiations at the HZB Cyclotron	radiation, experiment, proton, cyclotron	178
	J. Bundesmann, A. Denker, G. Kourkafas HZB, Berlin, Germany J. Heufelder, A. Weber Charite, Berlin, Germany P. Mühldorfer BHT, Berlin, Germany
	In the context of radiotherapy, Flash irradiations mean the delivery of high dose rates of more than 40 Gy/s, in a short time of less than one second. The expectation of the radio-oncologists are lesser side effects while maintaining the tumour control when using Flash. Clinically acceptable deviations of the applied dose to the described dose are less than 3%. Our accelerator control system is well suited for the standard treatment of ocular melanomas with irradiaton times of 30 s to 60 s. However, it is too slow for the short times required in Flash. Thus, a dedicated beam delivery control system has been developed, permitting irradiation times down to 7 ms with a maximal dose variation of less than 3%.

MO4BCO01	Using BDD Testing in SKAO: Challenges and Opportunities	software, TANGO, distributed, interface	183
	V.L. Allan University of Cambridge, Cambridge, United Kingdom G. Brajnik IDS, Udine, Italy L.R. Brederode SKAO, Macclesfield, United Kingdom
	Defining what a system should do is one of the hardest parts of system design. Using Behaviour Driven Design (BDD) techniques can help, and also help define the tests needed to check that the desired behaviour is implemented. We describe the challenges and opportunities that arise when adopting these techniques, including both technical and social issues, and especially why in our case BDD techniques provide significant value. We present our pathway towards using BDD and the lessons learned. By trying to use BDD testing to run integration tests, it enabled the identification of gaps in the testing infrastructure, particularly the TANGO testing infrastructure, and gaps in developers’ understanding of the system design. This allowed SKAO to take steps to improve the tests, the infrastructure, and the design, by integrating BDD techniques into the full product development lifecycle and using them also for monitoring the development process and the quality of software products.

	Diamond Light Source is currently developing a web-based EPICS control system User Interface (UI). This will replace the use of EDM and the Eclipse-based CS-Studio at Diamond, and it will integrate with future Acquisition and Analysis software. For interoperability, it will use the Phoebus BOB file format. The architecture consists of a back-end application using EPICS Python libraries to obtain PV data and the query language GraphQL to serve these data to a React-based front end. A prototype was made in 2021, and we are now doing further development from the prototype to meet the first use cases. Our current work focuses on the back-end application, Coniql, and for the query interface we have selected the Strawberry GraphQL implementation from the many GraphQL libraries available. We discuss the reasons for this decision, highlight the issues that arose with GraphQL, and outline our solutions. We also demonstrate how well these libraries perform within the context of the EPICS web UI requirements using a set of performance metrics. Finally, we provide a summary of our development plans.

MO4BCO03	Protecting Your Controls Infrastructure Supply Chain	software, operation, framework, software-component	196
	B. Copy, F. Ehm, P.J. Elson, S.T. Page, J.-B. de Martel CERN, Meyrin, Switzerland M. Pratoussy CPE Lyon, Villeurbanne, France L. Van Mol Birmingham University, Birmingham, United Kingdom
	Supply chain attacks have been constantly increasing since being first documented in 2013. Profitable and relatively simple to put in place for a potential attacker, they compromise organizations at the core of their operation. The number of high profile supply chain attacks has more than quadrupled in the last four years and the trend is expected to continue unless countermeasures are widely adopted. In the context of open science, the overwhelming reliance of scientific software development on open-source code, as well as the multiplicity of software technologies employed in large scale deployments make it increasingly difficult for asset owners to assess vulnerabilities threatening their activities. Recently introduced regulations by both the US government (White House executive order EO14028) and the EU commission (E.U. Cyber Resilience Act) mandate that both Service and Equipment suppliers of government contracts provide Software Bills of Materials (SBOM) of their commercial products in a standard and open data format. Such SBOM documents can then be used to automate the discovery, and assess the impact of, known or future vulnerabilities and how to best mitigate them. This paper will explain how CERN investigated the implementation of SBOM management in the context of its accelerator controls infrastructure, which solutions are available on the market today, and how they can be used to gradually enforce secure dependency lifecycle policies for the developer community.

MO4BCO04	Improving Control System Software Deployment at MAX IV	TANGO, software, device-server, Linux	201
	B. Bertrand, A. Freitas, A.F. Joubert MAX IV Laboratory, Lund University, Lund, Sweden J.T. Kowalczyk S2Innovation, Kraków, Poland
	The control systems of large research facilities like synchrotrons are composed of many different hardware and software parts. Deploying and maintaining such systems require proper workflows and tools. MAX IV has been using Ansible to manage and deploy its full control system, both software and infrastructure, for many years with great success. We detail further improvements: defining Tango devices as configuration, and automated deployment of specific packages when tagging Gitlab repos. We have now adopted Conda as our primary packaging tool instead of the Red Hat Package Manager (RPM). This allows us to keep up with the rapidly changing Python ecosystem, while at the same time decoupling Operating System upgrades from the control system software. For better management, we have developed a Prometheus-based tool that reports on the installed versions of each package on each machine. This paper will describe our workflow and discuss the benefits and drawbacks of our approach.

MO4BCO05	Apples to Oranges: A Comparison of EPICS Build and Deployment Systems	EPICS, site, LLRF, MMI	205
	S.C.F. Rose, D.H.C. Araujo, L.A. Mello Magalhães, A.L. Olsson ESS, Lund, Sweden
	ESS currently uses two different systems for managing the build and deployment of EPICS modules. Both of these use modules that are packaged and prepared to be dynamically loaded into soft IOCs, based on the require module developed at PSI. The difference is the deployment: For the accelerator, we use a custom utility to define and build an EPICS environment which is then distributed on a global shared filesystem to the production and lab networks. For the neutron instrumentation side, in contrast, we use conda to build individual EPICS environments for each IOC, where the underlying packages are stored on a shared artifactory server. In each case, the goal is to provide a repeatable and controllable mechanism to produce a consistent EPICS environment for IOCs in use at ESS. The difference (other than the tools and storage) is in some sense philosophical: should a software environment be defined at build-time or at run-time? In this presentation we will provide an overview of some of the challenges, contrasts, and lessons learned from these two different but related approaches to EPICS module deployment.

	G.M. Marinkovic, D. Anicic, R. Ditter, B. Keil, J. Purtschert, M. Roggli PSI, Villigen PSI, Switzerland
	At PSI we are combining the hardware, firmware, operating system, control system, embedded event system, operation and supervision in a Beam Position Monitor (BPM) system for 24/7 accelerator operation, using a Multi-Processing-System-on-Chip (MPSoC) of type Xilinx Zynq UltraScale+. We presently use MPSoCs for our latest generic BPM electronics platform called "DBPM3" in the Athos soft X-ray branch, as well as for new BPMs and general controls hardware and devices for SLS 2.0, a major upgrade of the Swiss Light Source. We are also in the process of upgrading our previous "MBU" (modular BPM Unit) platform for the SwissFEL linac and hard X-ray "Aramis" from external VMEbus based IOCs to integrated add-on cards with MPSoC IOCs. On all these MPSoCs, we are integrating an EPICS IOC, event receiver, measurement and feedback data real-time processing on a single chip. In this contribution, we describe our experience with the tight integration and daily operation of the various firmware and software components and features on the MPSoC, using the BPM system also to discuss general aspects relevant for other systems and components discussed in other PSI contributions on this conference.

TU1BCO01	A Workflow for Training and Deploying Machine Learning Models to EPICS	EPICS, GPU, framework, software	244
	M.F. Leputa, K.R.L. Baker, M. Romanovschi STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom
	The transition to EPICS as the control system for the ISIS Neutron and Muon Source accelerators is an opportunity to more easily integrate machine learning into operations. But developing high quality machine learning (ML) models is insufficient. Integration into critical operations requires good development practices to ensure stability and reliability during deployment and to allow robust and easy maintenance. For these reasons we implemented a workflow for training and deploying models that utilize off-the-shelf, industry-standard tools such as MLflow. Our experience of how adoption of these tools can make developer’s lives easier during the training phase of a project is discussed. We describe how these tools may be used in an automated deployment pipeline to allow the ML model to interact with our EPICS ecosystem through Python-based IOCs within a containerized environment. This reduces the developer effort required to produce GUIs to interact with the models within the ISIS Main Control Room as tools familiar to operators, such as Phoebus, may be used.

TU1BCO03	Systems Modelling, AI/ML Algorithms Applied to Control Systems	monitoring, hardware, software, software-component	257
	S.A. Mnisi SARAO, Cape Town, South Africa
	Funding: National Research Foundation (South Africa) The 64 receptor (with 20 more being built) radio telescope in the Karoo, South Africa, comprises a large number of devices and components connected to the Control-and-Monitoring (CAM) system via the Karoo Array Telescope Communication Protocol (KATCP). KATCP is used extensively for internal communications between CAM components and other subsystems. A KATCP interface exposes requests and sensors; sampling strategies are set on sensors, ranging from several updates per second to infrequent on-change updates. The sensor samples are of different types, from small integers to text fields. The samples and associated timestamps are permanently stored and made available for scientists, engineers and operators to query and analyze. This is a presentation on how to apply Machine Learning tools which utilize data-driven algorithms and statistical models to analyze sensor data sets and then draw inferences from identified patterns or make predictions based on them. The algorithms learn from the sensor data as they run against it, unlike traditional rules-based analytics systems that follow explicit instructions. Since this involves data preprocessing, we will go through how the MeerKAT telescope data storage infrastructure (called Katstore) manages the voluminous variety, velocity and volume of this data.

TU1BCO04	Laser Focal Position Correction Using FPGA-Based ML Models	laser, network, FPGA, simulation	262

	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of High Energy Physics under Award Number DE-SC 00259037. High repetition-rate, ultrafast laser systems play a critical role in a host of modern scientific and industrial applications. We present a diagnostic and correction scheme for controlling and determining laser focal position by utilizing fast wavefront sensor measurements from multiple positions to train a focal position predictor. This predictor and additional control algorithms have been integrated into a unified control interface and FPGA-based controller on beamlines at the Bella facility at LBNL. An optics section is adjusted online to provide the desired correction to the focal position on millisecond timescales by determining corrections for an actuator in a telescope section along the beamline. Our initial proof-of-principle demonstrations leveraged pre-compiled data and pre-trained networks operating ex-situ from the laser system. A framework for generating a low-level hardware description of ML-based correction algorithms on FPGA hardware was coupled directly to the beamline using the AMD Xilinx Vitis AI toolchain in conjunction with deployment scripts. Lastly, we consider the use of remote computing resources, such as the Sirepo scientific framework, to actively update these correction schemes and deploy models to a production environment. M.S.

	Funding: National Nuclear Security Administration (NNSA) This work presents a review of the shift in tuning methods employed at the Los Alamos Neutron Science Center (LANSCE). We explore the tuning categories and methods employed in four key sections of the accelerator, namely the Low-Energy Beam Transport (LEBT), the Drift Tube Linac (DTL), the side-Coupled Cavity Linac (CCL), and the High-Energy Beam Transport (HEBT). The study additionally presents the findings of employing novel software tools and algorithms to enhance each domain’s beam quality and performance. This study showcases the efficacy of integrating model-driven and model-independent tuning techniques, along with acceptance and adaptive tuning strategies, to enhance the optimization of beam delivery to experimental facilities. The research additionally addresses the prospective strategies for augmenting the control system and diagnostics of LANSCE. R.W. Garnett, J. Phys.: Conf. Ser. 1021 012001 A. Scheinker, Rev. ST Accel.

Xu Northwestern University, EVANSTON, USA A. Narayanan Northern Illinois University, DeKalb, Illinois, USA
	The Fermilab Main Injector enclosure houses two accelerators, the Main Injector and Recycler Ring. During normal operation, high intensity proton beams exist simultaneously in both. The two accelerators share the same beam loss monitors (BLM) and monitoring system. Deciphering the origin of any of the 260 BLM readings is often difficult. The (Accelerator) Real-time Edge AI for Distributed Systems project, or READS, has developed an AI/ML model, and implemented it on fast FPGA hardware, that disentangles mixed beam losses and attributes probabilities to each BLM as to which machine(s) the loss originated from in real-time. The model inferences are then streamed to the Fermilab accelerator controls network (ACNET) where they are available for operators and experts alike to aid in tuning the machines.

TU2BCO02	Protection Layers Design for the High Luminosity LHC Full Remote Alignment System	software, alignment, operation, hardware	285
	B. Fernández Adiego, E. Blanco Viñuela, A. Germinario, H. Mainaud Durand, M. Sosin CERN, Meyrin, Switzerland
	The Full Remote Alignment System (FRAS) is a complex measurement, alignment and control system designed to remotely align components of the Large Hadron Collider (LHC) following its High Luminosity upgrade. The purpose of FRAS is to guarantee optimal alignment of the strong focusing magnets and associated components near the experimental interaction points, while at the same time limiting the radiation dose to which surveyors in the LHC tunnel are subjected. A failure in the FRAS control system, or an operator mistake, could provoke a non desired displacement of a component that could lead to damage of neighbouring equipment. Such an incident would incur a considerable repair cost both in terms of money and time. To mitigate this possibility, an exhaustive risk analysis of FRAS has been performed, with the design of protection layers according to the IEC 61511 standard proposed. This paper presents the different functional safety techniques applied to FRAS, reports on the current project status, and introduces the future activities to complete the safety life cycle.

TU2AO01	The Hybrid Identity of a Control System Organization: Balancing Support, Product, and R&D Expectations	software, framework, operation, experiment	303
	S. Baymani PSI, Villigen PSI, Switzerland
	Controls organizations are often expected to fulfill a dual role as both a support organization and an R&D organization, providing advanced and innovative services. This creates a tension between the need to provide services and the desire and necessity to develop cutting-edge technology. In addition, Controls organizations must balance the competing demands of product development, maintenance and operations, and innovation and R&D. These conflicting expectations can lead to neglect of long-term strategic issues and create imbalances within the organization, such as technical debt and lack of innovation. This paper will explore the challenges of navigating these conflicting expectations and the common traps, risks, and consequences of imbalances. Drawing on our experience at PSI, we will discuss specific examples of conflicts and their consequences. We will also propose solutions to overcome or improve these conflicts and identify a long-term, sustainable approach for a hybrid organization such as Controls . Our proposals will cover strategies for balancing support and product development, improving communication, and enabling a culture of innovation. Our goal is to spark a broader discussion around the identity and role of control system organizations within large laboratory organizations, and to provide concrete proposals for organizations looking to balance competing demands and build a sustainable approach to control systems and services.

TU2AO02	Textual Analysis of ICALEPCS and IPAC Conference Proceedings: Revealing Research Trends, Topics, and Collaborations for Future Insights and Advanced Search	cavity, cryogenics, laser, LLRF	309
	A. Sulc, A. Eichler, T. Wilksen DESY, Hamburg, Germany
	Funding: This work was supported by HamburgX grant LFF-HHX-03 to the Center for Data and Computing in Natural Sciences (CDCS) from the Hamburg Ministry of Science, Research, Equalities and Districts. In this paper, we show a textual analysis of past ICALEPCS and IPAC conference proceedings to gain insights into the research trends and topics discussed in the field. We use natural language processing techniques to extract meaningful information from the abstracts and papers of past conference proceedings. We extract topics to visualize and identify trends, analyze their evolution to identify emerging research directions and highlight interesting publications based solely on their content with an analysis of their network. Additionally, we will provide an advanced search tool to better search in the existing papers to prevent duplication and easier reference findings. Our analysis provides a comprehensive overview of the research landscape in the field and helps researchers and practitioners to better understand the state-of-the-art and identify areas for future research.

TU2AO03	A Successful Emergency Response Plan: Lessons in the Controls Section of the ALBA Synchrotron	operation, software, MMI, synchrotron	316
	G. Cuní, O. Matilla, J. Nicolàs, M. Pont ALBA-CELLS, Cerdanyola del Vallès, Spain
	These are challenging times for research institutes in the field of software engineering. Our designs are becoming increasingly complex, and a software engineer needs years of experience to become productive. On the other hand, the software job market is very dynamic, and a computer engineer receives tens of offers from private companies with attractive salaries every year. Occasionally, the perfect storm can occur, and in a short period of time, several key people in a group with years of experience leave. The situation is even more critical when the institute is plunged into a high growth rate with several new instruments under way. Naturally, engaged teams will resist reducing operational service quality, but, on the other hand, the new installations milestones dates will approach quickly. This article outlines the decision-making process and the measures taken to cope with this situation in the ALBA Synchroton’s Controls Section. The plan included reorganizing teamwork, but more importantly, redefining the relationship with our clients and prioritization processes. As a result, the team was restructured and new roles were created. In addition, effective coordination was vital, and new communication channels were established to ensure smooth workflows. The emergency peak period is over in our case, but we have learned a lot of lessons and implemented many changes that will stay with us. They have made us more efficient and more resilient in case of future emergencies.

TU2AO04	Ensuring Smooth Controls Upgrades During Operation	operation, software, interface, GUI	321
	M. Pace, F. Hoguin, E. Matli, W. Sliwinski, B. Urbaniec CERN, Meyrin, Switzerland
	The CERN Accelerator Controls systems have to remain as stable as possible for operations. However, there are inevitable needs to introduce changes to provide new functionalities and conduct important consolidation activities. To deal with this, a formal procedure and approval process, the Smooth Upgrades procedure, was introduced and refined over a number of years. This involves declaring foreseen Controls changes as a function of the accelerator schedules, validating them with stakeholders, and organising their deployment in the production environment. All of this with the aim of minimising the impact on accelerator operation. The scope of this activity is CERN-wide, covering changes developed by all CERN units involved in Controls and encompassing the whole CERN accelerator and facility complex. In 2022, the mandate was further extended with a more formal approach to coordinate changes of the software interfaces of the devices running on front-end computers, which form a critical part of the smooth deployment process. Today, Smooth Upgrades are considered a key contributor to the performance and stability of the CERN Control system. This paper describes the Smooth Upgrades procedure and the underlying processes and tools such as schedule management, change management, and the monitoring of device usage. The paper also includes the major evolutions which allowed the current level of maturity and efficiency to be reached. Ideas for future improvements will also be covered.

TU2AO05	Maintenance of the National Ignition Facility Controls Hardware System	operation, target, laser, experiment	328
	J.L. Vaher, G.K. Brunton, J. Dixon LLNL, Livermore, USA
	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. At the National Ignition Facility (NIF), achieving fusion ignition for the first time ever in a laboratory required one of the most complex hardware control systems in the world. With approximately 1,200 control racks, 66,000 control points, and 100, 000 cables, maintaining the NIF control system requires an exquisite choreography around experimental operations while adhering to NIF’s safety, security, quality, and efficiency requirements. To ensure systems operate at peak performance and remain available at all times to avoid costly delays, preventative maintenance activities are performed two days per week as the foundation of our effective maintenance strategy. Reactive maintenance addresses critical path issues that impact experimental operations through a rapid response 24x7 on-call support team. Prioritized work requests are reviewed and approved daily by the facility operations scheduling team. NIF is now in the second decade of operations, and the aging of many control systems is threatening to affect performance and availability, potentially impacting planned progress of the fusion ignition program. The team is embarking on a large-scale refurbishment of systems to mitigate this threat. Our robust maintenance program will ensure NIF can capitalize on ignition and push the facility to even greater achievements. This paper will describe the processes, procedures, and metrics used to plan, coordinate, and perform controls hardware maintenance at NIF. LLNL Release Number: LLNL-ABS-848420

	R. Lange, H. Kim, A. Žagar ITER Organization, St. Paul lez Durance, France V. Costa, J. Nieto, M. Ruiz UPM-I2A2, Madrid, Spain
	Funding: Partially funded by PID2019-108377RB-C33/MCIN/AEI (Agencia Estatal de Investigación) /10.13039/501100011033 and PID2022-137680OB-C33/MCIN/AEI /10.13039/501100011033 / FEDER/ and the European Union. As part of the effort to standardize the control system environment of ITER’s in-kind delivered >170 plant systems, the Controls Division publishes CODAC Core System (CCS), a complete Linux-based control system software distribution. In the past, a large part of the integrated and end-to-end software testing for CCS was executed manually, using many long and complex test plan documents. As the project progress introduces increasing scope and higher quality requirements, that approach was not maintainable in the long term. ITER CODAC and its partners have started a multi-year effort converting manual tests to automated tests, inside the so-called Framework for Integration Testing (FIT), which itself is being developed and gradually extended as part of the effort. This software framework is complemented by a dedicated hardware test stand setup, comprising specimens of the different controllers and I/O hardware supported by CCS. FIT and the test stand will allow to run fully scripted hardware-in-the-loop (HIL) tests and allow functional verification of specific software modules as well as different end-to-end use cases.

TUMBCMO02	EPICS Java Developments	EPICS, experiment, software, framework	342
	KS. Saintin, P. Lotrus CEA-IRFU, Gif-sur-Yvette, France L. Caouën CEA-DRF-IRFU, France
	The IRFU/DIS software control team is involved from feasibility studies to the deployment of equipment covering low level (hardware, PLC) to high level (GUI supervision). For our experiments, we are using two mains frameworks: - MUSCADE, a full Java in-house solution embedded SCADA dedicated to small and compact experiments controlled by PLC (Programmable Logic Controller), only compatible with Windows Operating System (OS) for the server side. - EPICS, a distributed control systems to operate devices such as particle accelerators, large facilities and major telescopes, mostly deployed on Linux OS environments. EPICS frameworks provides several languages for bindings and server interfaces such as C/C++, Python and Java. However, most of the servers also called IOC developed in the community are based on C/C++ and Linux OS System. EPICS also provides extensions developed in Java such as the EPICS Archiver Appliance, Phoebus Control-Studio** (GUI), and Display Web Runtime (Web Client). All these tools depend on CAJ (a pure Java implementation Channel Access Library). Today, MUSCADE users use to work under Windows, and they need intuitive tools that provide the same features than MUSCADE. Thus, research and development activities mainly focus on EPICS solution adaptation. It aims to explore further CAJ library, especially on the server side aspect. In order to achieve this goal, several developments have been carried out since 2018. * IRFU https://irfu.cea.fr/en EPICS https://epics-controls.org/ * IOC Input Output Controller **** Phoebus Control-Studio https://control-system-studio.readthedocs.io/

TUMBCMO07	Dynamic Control Room Interfaces for Complex Particle Accelerator Systems	interface, operation, lattice, embedded	351
	B.E. Bolling, G. Fedel, M. Muñoz, D.N. Nordt ESS, Lund, Sweden
	The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Commissioning of the first part of the accelerator has begun and the requirements on the control system interfaces varies greatly as progress is made and new systems are added. In this paper, three such applications are discussed in separate sections. A Navigator interface was developed for the control room interfaces aimed towards giving operators and users a clear and structured way towards quickly finding the needed interface(s) they need. The construction of this interface is made automatically via a Python-based application and is built on applications in any directory structure both with and without developer interference (fully and semi-automatic methods). The second interface discussed in this paper is the Operations Accelerator Synoptic interface, which uses a set of input lattices and system interface templates to construct configurable synoptic view of the systems in various sections and a controller panel for any selected system. Lastly for this paper there is a configurable Radio Frequency Orchestration interface for Operations, which allows in-situ modification of the interface depending on which systems and components are selected.

TUMBCMO08	Extending Phoebus Data Browser to Alternative Data Sources	EPICS, database, interface, experiment	355
	M. Romanovschi, I.D. Finch, G.D. Howells STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom
	The Phoebus user interface to EPICS is an integral part of the new control system for the ISIS Neutron and Muon Source accelerators and targets. Phoebus can use the EPICS Archiver Appliance, which has been deployed as part of the transition to EPICS, to display the history of PVs. However, ISIS data has and continues to be stored in the InfluxDB time series database. To enable access to this data, a Python application to interface between Phoebus and other databases has been developed. Our implementation utilises Quart, an asynchronous web framework, to allow multiple simultaneous data requests. Google Protocol Buffer, natively supported by Phoebus, is used for communication between Phoebus and the database. By employing subclassing, our system can in principle adapt to different databases, allowing flexibility and extensibility. Our open-source approach enhances Phoebus’s capabilities, enabling the community to integrate it within a wider range of applications.

TUMBCMO09	Front-End Monitor and Control Web Application for Large Telescope Infrastructures: A Comparative Analysis	TANGO, framework, interface, operation	359
	S. Di Frischia, M. Canzari INAF - OAAB, Teramo, Italy V. Alberti INAF-OAT, Trieste, Italy A. Georgiou CGI, Edinburgh, United Kingdom H.R. Ribeiro Universidade do Porto, Faculdade de Ciências, Porto, Portugal
	A robust monitor and control front-end application is a crucial feature for large and scalable radio telescope infrastructures such LOFAR and SKA, whereas the control system is required to manage numerous attribute values at a high update rate, and thus the operators must rely on an affordable user-interface platform which covers the whole range of operations. In this paper two state-of-the-art web applications such Grafana and Taranta are taken into account, developing a comparative analysis between the two software suites. Such a choice is motivated mostly because of their widespread use together with the TANGO Controls Framework, and the necessity to offer a ground of comparison for large projects dealing with the development of a monitor and control GUI which interfaces to TANGO. We explain at first the general architecture of both systems, and then we create a typical use-case where an interactive dashboard is built to monitor and control a hardware device. Then, we set up some comparable metrics to evaluate the pros and cons of both platforms, regarding the technical and operational requirements, fault tolerances, developers and operators efforts, and so on. In conclusion, the comparative analysis and its results are summarized with the aim to offer the stakeholders a basis for future choices.

	T. Ashwarya, M. Ikegami, J. LeTourneau, A.C. Morton FRIB, East Lansing, Michigan, USA
	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 For more than a decade, the Eclipse-based Control System Studio has provided FRIB with a rich user interface to its EPICS-based control system. At FRIB, we use the Alarm Handler, BOY Display Manager, Scan Monitor/Editor, Channel Client, Save-and-Restore, and Data Browser to monitor and control various parts of the beamline. Our engineers have developed over 3000 displays using the BOY display manager mapping various segments and areas of the FRIB beamline. CS-Studio Phoebus is the latest next-generation upgrade to the Eclipse-based CS-Studio, which is based on the modern JavaFX-based graphics and aims toward providing existing functionalities and more. FRIB has already transitioned away from the old BEAST alarm servers to the new Kafka-based Phoebus alarm servers which have been monitoring thousands of our EPICS PVs with its robust monitoring and notifying capabilities. We faced certain challenges with conversion of FRIB’s thousands of displays and to address those we deployed scripts to help the bulk conversion of screens with automated mapping between BOY and Display Builder and also continually improved the Phoebus auto-conversion tool. This paper details the ongoing transition of FRIB from Eclipse-based CS-Studio to Phoebus and various adaptations and solutions that we used to ease this transition for our users. Moving to the new Phoebus-based services and client have provided us with an opportunity to rectify and improve on certain issues known to have existed with Eclipse-based CS-Studio and its services.

TUMBCMO12	Multi-Dimensional Spectrogram Application for Live Visualization and Manipulation of Large Waveforms	cavity, EPICS, proton, real-time	368
	B.E. Bolling, A.A. Gorzawski, J. Peterson ESS, Lund, Sweden
	The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Protons are accelerated via cavity fields through various accelerating structures that are powered by Radio-Frequency (RF) power. As the cavity fields may break down due to various reasons, usually post-mortem data of such events contain the information needed regarding the cause. In other events, the underlying cause may have been visible on previous beam pulses before the interlock triggering event. The Multi-Dimensional Spectrogram Application is designed to be able to collect, manipulate and visualize large waveforms at high repetition rates, with the ESS goal being 14 Hz, for example cavity fields, showing otherwise unnoticed temporary breakdowns that may explain the sometimes-unknown reason for increased power (compensating for those invisible temporary breakdowns). The first physical event that was recorded with the tool was quenching of a superconducting RF cavity in real time in 3D. This paper describes the application developed using Python and the pure-python graphics and GUI library PyQtGraph and PyQt5 with Python-OpenGL bindings.

TUMBCMO13	Applications of Artificial Intelligence in Laser Accelerator Control System	laser, target, simulation, experiment	372
	F.N. Li, K.C. Chen, Z. Guo, Q.Y. He, C. Lin, Q. Wang, Y. Xia, M.X. Zang PKU, Beijing, People’s Republic of China
	Funding: the National Natural Science Foundation of China (Grants No. 11975037, NO. 61631001 and No. 11921006), and the National Grand Instrument Project (No. 2019YFF01014400 and No. 2019YFF01014404). Ultra-intense laser-plasma interactions can produce TV/m acceleration gradients, making them promising for compact accelerators. Peking University is constructing a proton radiotherapy system prototype based on PW laser accelerators, but transient processes challenge stability control, critical for medical applications. This work demonstrates artificial intelligence’s (AI) application in laser accelerator control systems. To achieve micro-precision alignment between the ultra-intense laser and target, we propose an automated positioning program using the YOLO algorithm. This real-time method employs a convolutional neural network, directly predicting object locations and class probabilities from input images. It enables precise, automatic solid target alignment in about a hundred milliseconds, reducing experimental preparation time. The YOLO algorithm is also integrated into the safety interlocking system for anti-tailing, allowing quick emergency response. The intelligent control system also enables convenient, accurate beam tuning. We developed high-performance virtual accelerator software using "OpenXAL" and GPU-accelerated multi-particle beam transport simulations. The software allows real-time or custom parameter simulations and features control interfaces compatible with optimization algorithms. By designing tailored objective functions, desired beam size and distribution can be achieved in a few iterations.

	J. Maldonado, S.L. Clark, W. Fu, S. Nemesure BNL, Upton, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 The electronic logbook (elog) system used at Brookhaven National Laboratory’s Collider-Accelerator Department (C-AD) allows users to customize logbook settings, including specification of favorite logbooks. Using machine learning techniques, customizations can be further personalized to provide users with a view of entries that match their specific interests. We will utilize natural language processing (NLP), optical character recognition (OCR), and topic models to augment the elog system. NLP techniques will be used to process and classify text entries. To analyze entries including images with text, such as screenshots of controls system applications, we will apply OCR. Topic models will generate entry recommendations that will be compared to previously tested language processing models. We will develop a command line interface tool to ease automation of NLP tasks in the controls system and create a web interface to test entry recommendations. This technique will create recommendations for each user, providing custom sets of entries and possibly eliminate the need for manual searching.

TUMBCMO18	Upgrade of the AGOR Cyclotron Control System at UMCG-PARTREC	PLC, operation, cyclotron, software	391
	O.J. Kuiken, A. Gerbershagen, P. Schakel, J. Schwab, J.K. van Abbema PARTREC, Groningen, The Netherlands
	The AGOR cyclotron began development in the late 1980s and was commissioned in 1997. In 2020, when the facility was transferred from the University of Groningen to the University Medical Center Groningen, it marked the start of an upgrade process aimed at ensuring reliable operation. Recent, current and upcoming upgrades and additions encompass the following: Firstly, the current OT network uses custom IO modules based on the outdated Bitbus fieldbus. A pilot study was conducted to evaluate the use of NI CompactRIO-based subracks for analog and digital IO. Also, a similar PLC-based solution is currently under investigation. Secondly, the current control system is based on Vsystem/Vista and alternatives are being investigated. Thirdly, PLCs are upgraded to a newer generation. Fourthly, the current harp electronics and beam current readout electronics both use components that are hard to procure and use a Bitbus interface. New, in-house designs constructed as generic I-V converters eliminate this fieldbus dependency. Fifthly, the present RF slow control employs feedback loops to regulate the RF power and phase. Our new design incorporates functional improvements and condenses several discrete modules into a single cassette, resulting in fewer expected issues with faulty cables and connectors, and enabling us to maintain a larger stock of spares. Finally, the UMCG Radiotherapy department is constructing a new beamline with support from the technical staff at UMCG-PARTREC. The control will be based on NI CompactRIO.

With multiple beamlines and experimental stations completed and in steady use, the facility is now approaching the third phase of development, which includes the final two of the 16 planned beamlines in user operation. The focus is on achieving operational excellence by optimizing reliability and performance. Meanwhile, the strategy for the coming years is driven by the need to accommodate a growing user base, exploring the possibility of operating a Soft X-ray Laser (SXL), and achieving the diffraction limit for 10 keV of the 3 GeV. The Technical Division is responsible for the control and computing systems of the entire laboratory. This new organization provides a coherent strategy and a clear vision, with the ultimate goal of enabling science. The increasing demand for more precise and efficient control systems has led to significant developments and maintenance efforts. Pushing the limits in remote access, data generation, time-resolved and fly-scan experiments, and beam stability requires the proper alignment of technology in IT infrastructure, electronics, software, data analysis, and management. This article discusses the motivation behind the updates, emphasizing the expansion of the control system’s capabilities and reliability. Lastly, the technological strategy will be presented to keep pace with the rapidly evolving technology landscape, ensuring that MAX IV is prepared for its next major upgrade.

	Operational since 2008, SOLEIL [1] is providing users with access to a wide range of experimental techniques thanks to its 29 beamlines, covering a broad energy range from THz to hard X-ray. In response to new scientific and societal challenges, SOLEIL is undergoing a major transformation with the ongoing SOLEIL II project. This project includes designing an ambitious Diffraction Limited Storage Ring (DLSR) [2] to increase performances in terms of brilliance, coherence, and flux, upgrading the beamlines to provide advanced methods, and driving a digital transformation in data- and user- oriented approaches. This paper presents the project organization and technical details studies for the ongoing upgrades, with a focus on the digital transformation required to address future scientific challenges. It will depict the computing and data management program with the presentation of the targeted IT architecture to improve automated and data-driven processes for optimizing instrumentation. The optimization program covers the facility reconstruction period as well as future operation, including the use of Artificial Intelligence (AI) techniques for data production management, decision-making, complex feedbacks, and data processing. Real-time processes are to be applied in the acquisition scanning design, where detectors and robotic systems will be coupled to optimize beam time.

TUMBCMO22	Integration of an MPSoC-based acquisition system into the CERN control system	GUI, software, instrumentation, interface	409
	E. Balci, I. Degl’Innocenti, M. Gonzalez-Berges, S. Jackson, M. Krupa CERN, Meyrin, Switzerland
	Funding: CERN Future generations of Beam Instrumentation systems will be based on Multiprocessor System on Chip (MPSoC) technology. This new architecture will allow enhanced exploitation of instrumentation signals from CERN’s accelerator complex, and has thus been chosen as the next platform for several emerging systems. One of these systems, for the HL-LHC BPM (High-Luminosity LHC Beam Position Monitors), is currently at a prototyping stage, and it is planned to test this prototype with signals from real monitors in CERN’s accelerators during 2023. In order to facilitate the analysis of the prototype’s performance, a strategy to integrate the setting, control and data acquisition within CERN’s accelerator control system has been developed. This paper describes the exploration of various options and eventual choices to achieve a functional system, covering all aspects from data acquisition from the gateware, through to eventual logging on the accelerator logging database. It also describes how the experiences of integrating this prototype will influence future common strategies within the accelerator sector, highlighting how specific problems were addressed, and quantifying the performance we can eventually expect in the final MPSoC-based systems.

TUMBCMO23	Development and New Perspectives on the LMJ Power Conditioning Modules	laser, software, MMI, experiment	415
	P. Torrent, J-P. Airiau, I. Issury CEA, LE BARP cedex, France
	The Laser MegaJoule (LMJ), a 176-beam laser French facility, located at the CEA* CESTA close to Bordeaux is part of the French Simulation Program, for improvement of theoretical models, high performance numerical simulations and experimental validations. It is designed to deliver about 1.4 MJ of energy on targets, for plasma and fusion experiments. With 15 bundles operational at the end of 2023, the operational capabilities are increasing gradually until the full completion of the LMJ facility by 2025. With the increasing of the Power Conditioning Modules (PCM), it has been observed more and more instabilities in the synchronization and the repeatability of the PCM’s triggering. For experiments based on 10 or more bundles, it has resulted in the issue of coupling the LMJ bundles with the PETAL laser and in the safety shutdown of the PCM due to the timeout of capacitors under high voltage. In this paper, a description of the LMJ PCM is first given. Then, the considered problem is presented with a detailed analysis and the software solution is finally presented with experimental results showing the gain in the reliability and effectiveness of the PCM during the LMJ-PETAL shots. * CEA : Commissariat à l Energie Atomique et aux Energies Alternatives

ITER Organization, St. Paul lez Durance, France

The ITER Tokamak is currently being assembled in southern France. In parallel, the supporting systems have completed installation and are under commissioning or operation. Over the last couple of years the electrical distribution, building services, liquid & gas, cooling water, reactive power compensation and cryoplant have been integrated, adding up to close to one million process variables. Those systems are operated, or under commissioning, from a temporary main control room or local control rooms close to the equipment using an integrated infrastructure. The ITER control system is therefore in production. As the ITER procurement is 90% in-kind, a major challenge has been the integration of the various systems provided by suppliers from the ITER members. Standardization, CODAC Core System software distribution, training and coaching have all played a positive role. Nevertheless, the integration has been more difficult than foreseen and the central team has been forced to rework much of the delivered software. In this paper we report on the current status of the ITER integrated control system with emphasize on lessons learned from integration of in-kind contributions.

The Linac Coherent Light Source complex at the SLAC National Accelerator Laboratory has been upgraded to add a new superconducting accelerator with beam rates up to 1MHz. Though the majority of the more than twenty accelerator control systems are based on LCLS designs, to accommodate the increase in repetition rate from 120Hz to 1MHz, many of the diagnostics and global control systems are upgraded to high performance platforms with standalone CPUs running linuxRT to host the EPICS based controls. With installation and checkouts for control systems completing in 2022, the phased approach to integration and commissioning recently completed with demonstration of the threshold key performance parameters and first light occurring in the Summer of 2023. This paper provides an overview of the LCLS-II accelerator control system architecture, upgrades, the multi-year installation, checkout, integration, commissioning, and lessons learned.

Concept and Design of an Extensible Middle-Layer Application Framework for Accelerator Operations and Development

DESY, Hamburg, Germany

Data collection and analysis are becoming increasingly vital not only for the experiments conducted with particle accelerators but also for their operation, maintenance, and development. Due to lack of feasible alternatives, experts regularly resort to writing task-specific scripts to perform actions such as (event triggered or temporary) data collection, system failure detection and recovery, and even simple high-level feedbacks. Often, these scripts are not shared and are deemed to have little reuse value, giving them a short lifetime and causing redundant work. We report on a modular Python framework for constructing middle-layer applications from a library of parameterized functionality blocks (modules) by writing a simple configuration file in a human-oriented format. This encourages the creation of maintainable and reusable modules while offering an increasingly powerful and flexible platform that has few requirements to the user. A core engine instantiates the modules according to the configuration file, collects the required data from the control system and distributes it to the individual module instances for processing. Additionally, a publisher-subscriber messaging system is provided for inter-module communication. We discuss architecture & design choices, current state and future goals of the framework as well as real use-case examples from the European XFEL.

The Square Kilometre Array (SKA) Telescope will be one of the largest and most complex scientific instruments ever built. The development of a reliable software for monitoring and controlling its operations is critical to the success of the entire SKA project. The Local Monitoring and Control of the Central Signal Processor (CSP. LMC) is a software responsible for controlling a key subsystem of the telescope, i.e. the Central Signal Processor (CSP). The software is implemented as a "device" within the TANGO framework, written in Python. In this paper we describe a testing strategy that addresses some typical problems of such a large and complex instrument. It is a multi-level strategy, based on a combination of automated tests (unit/component/integration), in the context of CI/CD practices. Software is also tested against errors and anomalous conditions that can occur while the CSP. LMC is interacting with external subsystems, which can be simulated. The paper also discusses needs and solutions based on data mining test results. This allows us to obtain statistics of unexpected failures and to investigate their causes. Furthermore, a database containing test results supports discovery of interesting and unexpected patterns of behaviors of the tests based on correlations about different test-related events and data. This helps us to develop a deeper understanding of the code’s functioning and to find suitable solutions to minimize unexpected behaviors. In addition it can be used also to support reliability testing.

Applying Standardised Software Architectural Concepts to Design Robust and Adaptable PLC Solutions

Between evolving requirements, additional feature requests and urgent maintenance tasks, the Programmable Logic Controllers (PLC) at the European X-Ray Free Electron Laser Facility (EuXFEL) have become subjected to an array of demands. As the maintainability effort towards the existing systems peak, the requirement for a sustainable solution become an ever pressing concern. Ultimately, in order to provide a PLC code base which can easily be supported and adapted to, a reworking was required from the ground up in the form of a new suite of libraries and tools. Through this, it was possible to bring standardised software principals into PLC design and development, conjunctively offering an interface into the existing code base for ongoing support of legacy code. The set of libraries are developed by incorporating software engineering principles and design patterns in test driven development within a layered architecture. In defining clear interfaces across all the architectural layers - from hardware, to the software representation of hardware, and clusters of software devices, the complexity of PLC development decreases down into modular blocks of unit tested code. Regular tasks such as the addition of features, modifications or process control can easily be performed due to the adaptability, flexibility and modularity of the core PLC code base.

Software development practices such as continuous integration and continuous delivery (CI/CD) are widely adopted by the National Ignition Facility (NIF) which helps to automate the software development, build, test, and deployment processes. However, using CI/CD in an embedded controller project poses several challenges due to the limited computing resources such as processing power, memory capacity and storage availability in such systems. This paper will present how CI/CD best practices were tailored and used to develop and deploy software for one of the NIF Master Oscillator Room (MOR) embedded controllers, which is based on custom designed hardware consisting of a microcontroller and a variety of laser sensors and drivers. The approach included the use of automated testing frameworks, customized build scripts, simulation environments, and an optimized build and deployment pipeline, leading to quicker release cycles, improved quality assurance and quicker defect correction. The paper will also detail the challenges faced during the development and deployment phases and the strategies used to overcome them. The experience gained with this methodology on a pilot project demonstrated that using CI/CD in embedded controller projects can be challenging, yet feasible with the right tools and strategies, and has the potential to be scaled and applied to the vast number of embedded controllers in the NIF control system.

We describe our Jenkins-based continuous integration system and Debian packaging methods, and their application to the rapid development of the ChimeraTK framework. ChimeraTK is a C++ framework for control system applications and hardware access with a high level of abstraction and consists of more than 30 constantly changing interdependent libraries. Each component has its own release cycle for rapid development, yet API and ABI changes must be propagated to prevent problems in dependent libraries and over 60 applications. We present how we configured a Jenkins-based continuous integration system to detect problems quickly and systematically for the rapid development of ChimeraTK. The Debian packaging system is designed to ensure the compatibility of binary interfaces (ABI) and of development files (API). We present our approach using build scripts that allow the deployment of rapidly changing libraries and their dependent applications as Debian packages. These even permit applications to load runtime plugins that draw from the same core library, yet are compiled independently.

The beamlines of the Swiss Light Source (SLS) predominantly rely on EPICS standards as their control interface but in contrast to many other facilities, there is up to now no standardized user interfacing component to orchestrate, monitor and provide feedback on the data acquisition. As a result, the beamlines have either adapted community solutions or developed their own high-level orchestration system. For the upgrade project SLS 2.0, a sub-project was initiated to facilitate a unified beamline and experiment control system. During a pilot phase and a first development cycle, libraries of the Bluesky project were used, combined with additional in-house developed services, and embedded in a service-based approach with a message broker and in-memory database. Leveraging the community solutions paired with industry standards, enabled the development of a highly modular system which provides the flexibility needed for a constantly changing scientific environment. One year after the development started, the system was already tested during many weeks of user operation and recently received the official approval by the involved divisions to be rolled out as part of the SLS 2.0 upgrade.

The fast solid sample scanner (FSSS) used at the HED instrument of the European XFEL (EuXFEL) enables data collection from multiple samples mounted into standardized frames which can be exchanged via a transfer system without breaking the interaction chamber vacuum. In order to maximize the effective target shot repetition rate, it is a key requirement to use sample holders containing pre-aligned targets measured on an accurate level of a few micrometers. This contribution describes the automated sample delivery workflow for performing solid sample scanning using the FSSS. This workflow covers the entire process, from automatically identifying target positions within the sample, using machine learning algorithms, to set the parameters needed to perform the scans. The integration of this solution into the EuXFEL control system, Karabo, not only allows to control and perform the scans with the existing scan tool but also provides tools for image annotation and data acquisition. The solution thus enables the storage of data and metadata for future correlation across a variety of beamline parameters set during the experiment.

The endeavor of modernizing science data acquisition at BESSY II started 2019 [*] Significant achievements have been made: the Bluesky software ecosystem is now accepted framework for data acquisition, flow control and automation. It is operational at an increasing number of HZB beamlines, endstations and instruments. Participation in the global Bluesky collaboration is an extremely empowering experience. Promoting FAIR data principles at all levels developed a unifying momentum, providing guidance at less obvious design considerations. Now a joint demonstrator project of DESY, HZB, HZDR and KIT, named ROCK-IT (Remote Operando Controlled Knowledge-driven, IT-based), aims at portable solutions for fully automated measurements in the catalysis area of material science and is spearheading common developments. Foundation there is laid by Bluesky data acquisition, AI/ML support and analysis, modular sample environment, robotics and FAIR data handling. This paper puts present HZB controls projects as well as detailed HZB contributions to this conference [**] into context. It outlines strategies providing appropriate digital tools at a successor 4th generation light source BESSY III.

TimePix3 is a 65k hybrid pixel readout chip with simultaneous Time-of-Arrival (ToA) and Time-over-Threshold (ToT) recording in each pixel*. The chip operates without a trigger signal with a sparse readout where only pixels containing events are read out. The flexible architecture allows 40 MHits/s/cm² readout throughput, using simultaneous readout and acquisition by sharing readout logic with transport logic of superpixel matrix formed using 2x4 structure. The chip ToA records 1.5625 ns time resolution. The X-ray and charged particle events are counted directly. However, indirect neutron counts use 6Li fission in a scintillator matrix, such as ZnS(Ag). The fission space-charge region is limited to 5-9 um. A photon from scintillator material excites a photocathode electron, which is further multiplied in dual-stack MCP. The neutron count event is a cluster of electron events at the chip. We report on the EPICS areaDetector** ADTimePix3 driver that controls Serval*** using json commands. The driver directs data to storage and to a real-time processing pipeline and configures the chip. The time-stamped data are stored in raw .tpx3 file format and passed through a socket where the clustering software identifies individual neutron events. The conventional 2D images are available as images for each exposure frame, and a preview is useful for sample alignment. The areaDetector driver allows integration of time-enhanced capabilities of this detector into SNS beamlines controls and unprecedented time resolution.

ILL, Grenoble, France

Large-scale experimental facilities such as the ILL are designed to accommodate thousands of international visitors each year. Despite the annual influx of visitors, there has always been interest in options that don’t require users to travel to ILL. Remote access to instruments and datasets would unlock scientific opportunities for those less able to travel and contribute to global challenges like pandemics and global warming. Remote access systems can also increase the efficiency of experiments. For measurements that last a long time scientists can check regularly on the progress of the data taking from a distance, adjusting the instrument remotely if needed. Based on the VISA platform, the remote access becomes a cloud-based application which requires only a web browser and an internet connection. NOMAD Remote provides the same experience for users at home as though they were carrying out their experiment at the facility. VISA makes it easy for the experimental team to collaborate by allowing users and instrument scientists to share the same environment in real time. NOMAD Remote, an extension of the ILL instrument control software, enables researchers to take control of all instruments with continued hands-on support from local experts. Developed in-house, NOMAD Remote is a ground-breaking advance in remote access to neutron techniques. It allows full control of the extensive range of experimental environments with the highest security standards for data, and access to the instrument is carefully prioritised and authenticated.

Two new High-Dynamic Double-Crystal Monochromators (HD-DCM-Lite) are under installation in Sirius/LNLS for the new beamlines QUATI (quick-EXAFS) and SAPUCAIA (SAXS), which requires high in-position stability (5 nrad RMS in terms of pitch) whereas QUATI’s DCM demands the ability to perform quick sinusoidal scans in frequencies, for example 15 Hz at 4 mrad peak-to-peak amplitude. Therefore, this equipment aims to figure as an unparalleled bridge between slow step-scan DCMs, and channel-cut quick-EXAFS monochromators. In the previous conference, the dynamical modelling of HD-DCM-Lite was presented, indicating the expected performance to achieve QUATI and SAPUCAIA requirements. In this work, we are going to present the offline validation of the dynamical modelling, comparing to the solutions achieved for the previous version of LNLS HD-DCMs. This work also presents the hardware-based control architecture development, discussing the loop shaping technique and upgrades in the system, such as the increase of the position resolution, synchronization of the rotary stages, and FPGA code optimization. Furthermore, we describe how the motion controller was developed, given the high-performance motion control, such as complex control algorithm in parallel with a minimal jitter and the expectations for the beamlines commissioning regarding detector and undulator synchronization.

Achieving low emittance and high brightness in modern light sources requires stable beams, which are commonly achieved through feedback solutions. The MAX IV light source has two feedback systems, Fast Orbit Feedback (FOFB) and Slow Orbit Feedback (SOFB), operating in overlapping frequency regions. Currently in MAX IV, a general feedback device implemented in PyTango is used for slow orbit and trajectory correction, but an MPC controller for the beam orbit has been proposed to improve system robustness. The controller uses iterative optimisation of the system model, current measurements, dynamic states and system constraints to calculate changes in the controlled variables. The new device implements the MPC model according to the beam orbit response matrix, subscribes to change events on all beam position attributes and updates the control signal given to the slow magnets with a 10 Hz rate. This project aims to improve system robustness and reduce actuator saturation. The use of PyTango simplifies the implementation of the MPC controller by allowing access to high-level optimisation and control packages. This project will contribute to the development of a high-quality feedback control system for MAX IV accelerators.

The Sirius Fast Orbit Feedback System (FOFB) entered operation for users in November 2022. The system design aimed at minimizing the overall feedback loop delay, understood as the main performance bottleneck in typical FOFB systems. Driven by this goal, the loop update rate was chosen as high as possible, real-time processing was entirely done in FPGAs, BPMs and corrector power supplies were tightly integrated to the feedback controllers in MicroTCA crates, a small number of BPMs was included in the feedback loop and a dedicated network engine was used. These choices targeted a disturbance rejection crossover frequency of 1 kHz. To deal with the DC currents that build up in the fast orbit corrector power supplies, a method to transfer the DC control effort to the Slow Orbit Feedback System (SOFB) running in parallel was implemented. This contribution gives a brief overview of the system architecture and modelling, and reports on its commissioning, system identification and feedback loop optimization during its first year of operation.

This paper presents a comprehensive approach to modeling for control system design for a MeerKAT antenna. It focuses on dynamic modeling using time and frequency domain techniques, and lays the foundation for the design of a control system to meet the telescope’s stringent pointing and tracking requirements. The paper scope includes rigid body modelling of the antenna, system identification to obtain model parameters, and building a system model in Simulink. The Simulink model allows us to compare model performance with the measured antenna pointing, under various environmental conditions. The paper also integrates models for pointing disturbances, such as wind and friction. The integrated model is compared to the existing control setup. Wind disturbance plays a significant role in the pointing performance of the antenna, therefore the focus is placed on developing an appropriate wind model. This research will conclude by providing a well-documented, systematic control system design that is owned by SARAO and can be implemented to improve the pointing performance of the telescope.

The historical breakthrough experiment at the National Ignition Facility (NIF) produced fusion ignition in a laboratory for the first time and made headlines around the world. This achievement was the result of decades of research, thousands of people, and hardware and software systems that rivaled the complexity of anything built before. The NIF laser Automatic Alignment (AA) system has played a major role in this accomplishment. Each high yield shot in the NIF laser system requires all 192 laser beams to arrive at the target within 30 picoseconds and be aligned within 50 microns-half the diameter of human hair-all with the correct wavelength and energy. AA makes it possible to align and fire the 192 NIF laser beams efficiently and reliably several times a day. AA is built on multiple layers of complex calculations and algorithms that implement data and image analysis to position optical devices in the beam path in a highly accurate and repeatable manner through the controlled movement of about 66,000 control points. The system was designed to have minimum or no human intervention. This paper will describe AA’s evolution, its role in ignition, and future modernization.

CERN, Meyrin, Switzerland

Large industries operate energy-intensive equipment and energy efficiency is an important objective when trying to optimize the final energy consumption. CERN utilizes a large amount of electrical energy to run its accelerators, detectors and test facilities, with a total yearly consumption of 1.3 TWh and peaks of about 200 MW. Final energy consumption reduction can be achieved by dedicated technical solutions and advanced automation technologies, especially those based on optimization algorithms, have revealed a crucial role not only in keeping the processes within required safety and operational conditions but also in incorporating financial factors. MBPC (Model-Based Predictive Control) is a feedback control algorithm which can naturally integrate the capability of achieving reduced energy consumption when including economic factors in the optimization formulation. This paper reports on the experience gathered when applying non-linear MBPC to some of the contributors to the electricity bill at CERN: the cooling and ventilation plants (i.e. cooling towers, chillers, and air handling units). Simulation results with cooling towers showed significant performance improvements and energy savings close to 20% over conventional heuristic solutions. The control problem formulation, the control strategy validation using a digital twin and the initial results in a real industrial plant are reported together with the experience gained implementing the algorithm in industrial controllers.

Control Design Optimisations of Robots for the Maintenance and Inspection of Particle Accelerators

CERN, Meyrin, Switzerland

Automated maintenance and inspection systems have become increasingly important over the last decade for the availability of the accelerators at CERN. This is mainly due to improvements in robotic perception, control and cognition and especially because of the rapid advancement in artificial intelligence. The robotic service at CERN performed the first interventions in 2014 with robotic solutions from external companies. However, it soon became clear that a customized platform needed to be developed in order to satisfy the needs and in order to efficiently navigate through the cluttered, semi-structured environment. This led to the formation of a robotic fleet of about 20 different robotic systems that are currently active at CERN. In order to increase the efficiency and robustness of robotic platforms for future accelerators it is necessary to consider robotic interventions at the early design phase of such machines. Task specific solutions tailored to the specific needs can then be designed, which in general show higher efficiency than multipurpose industrial robotic systems. This paper presents current advances in the design and development of task specific robotic system for maintenance and inspection in particle accelerators, taking the 100 km long Future Circular Collider main tunnel as a use case. The requirements on such a robotic system, including the applied control strategies, are shown, as well as the optimization of the topology and geometry of the robotic system itself.

The South African Isotope Facility (SAIF) at iThemba LABS is well into its commissioning phase. The intention of SAIF is to free up our existing Separated Sector Cyclotron to do more physics research and to increase our radioisotope production and research capacity. An EPICS based control system, primarily utilising EtherCAT hardware, has been developed that spans the control of beamline equipment, target handling and bombardment stations, vault clearance and ARMS systems. Various building and peripheral services like cooling water and gases, HVAC and UPS have also been integrated into the control system via Modbus and OPCUA to allow for seamless control and monitoring. An overview of the SAIF facility and the EPICS based control system is presented. The control strategies, hardware and various EPICS and web based software and tools utilised are presented.

Synchrotron radiation beamlines transport X-rays from the electron beam source to the experimental sample. Precise alignment of the beamline optics is required to achieve adequate beam properties at the sample. This process is often done manually and can be quite time consuming. Further, we would like to know the properties at the sample in order to provide metadata for X-ray experiments. Diagnostics may provide some of this information but important properties may remain unmeasured. In order to solve both of these problems, we are developing tools to create fast online models (also known as digital twins). For this purpose, we are creating reduced models that fit into a hierarchy of X-ray models of varying degrees of complexity and runtime. These are implemented within a software framework called Sirepo-Bluesky* that allows for the computation of the model from within a Bluesky session which may control a real beamline. This work is done in collaboration with NSLS-II. We present the status of the software development and beamline measurements including results from the TES beamline. Finally, we present an outlook for continuing this work and applying it to more beamlines at NSLS-II and other synchrotron facilities around the world.

Large experimental facilities are essential for pushing the frontier of fundamental research. The control system is the key for smooth operation for Large experimental facilities. Recently many new types of facilities have emerged, especially in fusion community, new machines with completely different designs are being built. They are not as mature as accelerators. They need flexible control systems to accommodate frequent changes in hardware and experiment workflow. The ability to quickly integrate new device and sub-systems into the control system as well as to easily adopt new operation modes are important requirements for the control system. Here we present a control system framework that is built with standard web technology. The key is using HTTP RESTful web API as the fundamental protocol for maximum interoperability. This enables it to be integrated into the already well developed ecosystem of web technology. Many existing tools can be integrated with no or little development. for instance, InfluxDB can be used as the archiver, Node-RED can be used as the Scripter and Docker can be used for quick deployment. It has also made integration of in house developed embedded devices much easier. In this paper we will present the capability of this control system framework, as well as a control system for field-reversed configuration fusion experiment facility implemented with it.

In the context of radiotherapy, Flash irradiations mean the delivery of high dose rates of more than 40 Gy/s, in a short time of less than one second. The expectation of the radio-oncologists are lesser side effects while maintaining the tumour control when using Flash. Clinically acceptable deviations of the applied dose to the described dose are less than 3%. Our accelerator control system is well suited for the standard treatment of ocular melanomas with irradiaton times of 30 s to 60 s. However, it is too slow for the short times required in Flash. Thus, a dedicated beam delivery control system has been developed, permitting irradiation times down to 7 ms with a maximal dose variation of less than 3%.

Defining what a system should do is one of the hardest parts of system design. Using Behaviour Driven Design (BDD) techniques can help, and also help define the tests needed to check that the desired behaviour is implemented. We describe the challenges and opportunities that arise when adopting these techniques, including both technical and social issues, and especially why in our case BDD techniques provide significant value. We present our pathway towards using BDD and the lessons learned. By trying to use BDD testing to run integration tests, it enabled the identification of gaps in the testing infrastructure, particularly the TANGO testing infrastructure, and gaps in developers’ understanding of the system design. This allowed SKAO to take steps to improve the tests, the infrastructure, and the design, by integrating BDD techniques into the full product development lifecycle and using them also for monitoring the development process and the quality of software products.

Diamond Light Source is currently developing a web-based EPICS control system User Interface (UI). This will replace the use of EDM and the Eclipse-based CS-Studio at Diamond, and it will integrate with future Acquisition and Analysis software. For interoperability, it will use the Phoebus BOB file format. The architecture consists of a back-end application using EPICS Python libraries to obtain PV data and the query language GraphQL to serve these data to a React-based front end. A prototype was made in 2021, and we are now doing further development from the prototype to meet the first use cases. Our current work focuses on the back-end application, Coniql, and for the query interface we have selected the Strawberry GraphQL implementation from the many GraphQL libraries available. We discuss the reasons for this decision, highlight the issues that arose with GraphQL, and outline our solutions. We also demonstrate how well these libraries perform within the context of the EPICS web UI requirements using a set of performance metrics. Finally, we provide a summary of our development plans.

Supply chain attacks have been constantly increasing since being first documented in 2013. Profitable and relatively simple to put in place for a potential attacker, they compromise organizations at the core of their operation. The number of high profile supply chain attacks has more than quadrupled in the last four years and the trend is expected to continue unless countermeasures are widely adopted. In the context of open science, the overwhelming reliance of scientific software development on open-source code, as well as the multiplicity of software technologies employed in large scale deployments make it increasingly difficult for asset owners to assess vulnerabilities threatening their activities. Recently introduced regulations by both the US government (White House executive order EO14028) and the EU commission (E.U. Cyber Resilience Act) mandate that both Service and Equipment suppliers of government contracts provide Software Bills of Materials (SBOM) of their commercial products in a standard and open data format. Such SBOM documents can then be used to automate the discovery, and assess the impact of, known or future vulnerabilities and how to best mitigate them. This paper will explain how CERN investigated the implementation of SBOM management in the context of its accelerator controls infrastructure, which solutions are available on the market today, and how they can be used to gradually enforce secure dependency lifecycle policies for the developer community.

The control systems of large research facilities like synchrotrons are composed of many different hardware and software parts. Deploying and maintaining such systems require proper workflows and tools. MAX IV has been using Ansible to manage and deploy its full control system, both software and infrastructure, for many years with great success. We detail further improvements: defining Tango devices as configuration, and automated deployment of specific packages when tagging Gitlab repos. We have now adopted Conda as our primary packaging tool instead of the Red Hat Package Manager (RPM). This allows us to keep up with the rapidly changing Python ecosystem, while at the same time decoupling Operating System upgrades from the control system software. For better management, we have developed a Prometheus-based tool that reports on the installed versions of each package on each machine. This paper will describe our workflow and discuss the benefits and drawbacks of our approach.

Apples to Oranges: A Comparison of EPICS Build and Deployment Systems

ESS, Lund, Sweden

ESS currently uses two different systems for managing the build and deployment of EPICS modules. Both of these use modules that are packaged and prepared to be dynamically loaded into soft IOCs, based on the require module developed at PSI. The difference is the deployment: For the accelerator, we use a custom utility to define and build an EPICS environment which is then distributed on a global shared filesystem to the production and lab networks. For the neutron instrumentation side, in contrast, we use conda to build individual EPICS environments for each IOC, where the underlying packages are stored on a shared artifactory server. In each case, the goal is to provide a repeatable and controllable mechanism to produce a consistent EPICS environment for IOCs in use at ESS. The difference (other than the tools and storage) is in some sense philosophical: should a software environment be defined at build-time or at run-time? In this presentation we will provide an overview of some of the challenges, contrasts, and lessons learned from these two different but related approaches to EPICS module deployment.

At PSI we are combining the hardware, firmware, operating system, control system, embedded event system, operation and supervision in a Beam Position Monitor (BPM) system for 24/7 accelerator operation, using a Multi-Processing-System-on-Chip (MPSoC) of type Xilinx Zynq UltraScale+. We presently use MPSoCs for our latest generic BPM electronics platform called "DBPM3" in the Athos soft X-ray branch, as well as for new BPMs and general controls hardware and devices for SLS 2.0, a major upgrade of the Swiss Light Source. We are also in the process of upgrading our previous "MBU" (modular BPM Unit) platform for the SwissFEL linac and hard X-ray "Aramis" from external VMEbus based IOCs to integrated add-on cards with MPSoC IOCs. On all these MPSoCs, we are integrating an EPICS IOC, event receiver, measurement and feedback data real-time processing on a single chip. In this contribution, we describe our experience with the tight integration and daily operation of the various firmware and software components and features on the MPSoC, using the BPM system also to discuss general aspects relevant for other systems and components discussed in other PSI contributions on this conference.

The transition to EPICS as the control system for the ISIS Neutron and Muon Source accelerators is an opportunity to more easily integrate machine learning into operations. But developing high quality machine learning (ML) models is insufficient. Integration into critical operations requires good development practices to ensure stability and reliability during deployment and to allow robust and easy maintenance. For these reasons we implemented a workflow for training and deploying models that utilize off-the-shelf, industry-standard tools such as MLflow. Our experience of how adoption of these tools can make developer’s lives easier during the training phase of a project is discussed. We describe how these tools may be used in an automated deployment pipeline to allow the ML model to interact with our EPICS ecosystem through Python-based IOCs within a containerized environment. This reduces the developer effort required to produce GUIs to interact with the models within the ISIS Main Control Room as tools familiar to operators, such as Phoebus, may be used.

The 64 receptor (with 20 more being built) radio telescope in the Karoo, South Africa, comprises a large number of devices and components connected to the Control-and-Monitoring (CAM) system via the Karoo Array Telescope Communication Protocol (KATCP). KATCP is used extensively for internal communications between CAM components and other subsystems. A KATCP interface exposes requests and sensors; sampling strategies are set on sensors, ranging from several updates per second to infrequent on-change updates. The sensor samples are of different types, from small integers to text fields. The samples and associated timestamps are permanently stored and made available for scientists, engineers and operators to query and analyze. This is a presentation on how to apply Machine Learning tools which utilize data-driven algorithms and statistical models to analyze sensor data sets and then draw inferences from identified patterns or make predictions based on them. The algorithms learn from the sensor data as they run against it, unlike traditional rules-based analytics systems that follow explicit instructions. Since this involves data preprocessing, we will go through how the MeerKAT telescope data storage infrastructure (called Katstore) manages the voluminous variety, velocity and volume of this data.

High repetition-rate, ultrafast laser systems play a critical role in a host of modern scientific and industrial applications. We present a diagnostic and correction scheme for controlling and determining laser focal position by utilizing fast wavefront sensor measurements from multiple positions to train a focal position predictor. This predictor and additional control algorithms have been integrated into a unified control interface and FPGA-based controller on beamlines at the Bella facility at LBNL. An optics section is adjusted online to provide the desired correction to the focal position on millisecond timescales by determining corrections for an actuator in a telescope section along the beamline. Our initial proof-of-principle demonstrations leveraged pre-compiled data and pre-trained networks operating ex-situ from the laser system. A framework for generating a low-level hardware description of ML-based correction algorithms on FPGA hardware was coupled directly to the beamline using the AMD Xilinx Vitis AI toolchain in conjunction with deployment scripts. Lastly, we consider the use of remote computing resources, such as the Sirepo scientific framework*, to actively update these correction schemes and deploy models to a production environment.

This work presents a review of the shift in tuning methods employed at the Los Alamos Neutron Science Center (LANSCE). We explore the tuning categories and methods employed in four key sections of the accelerator, namely the Low-Energy Beam Transport (LEBT), the Drift Tube Linac (DTL), the side-Coupled Cavity Linac (CCL), and the High-Energy Beam Transport (HEBT). The study additionally presents the findings of employing novel software tools and algorithms to enhance each domain’s beam quality and performance. This study showcases the efficacy of integrating model-driven and model-independent tuning techniques, along with acceptance and adaptive tuning strategies, to enhance the optimization of beam delivery to experimental facilities. The research additionally addresses the prospective strategies for augmenting the control system and diagnostics of LANSCE.

The Fermilab Main Injector enclosure houses two accelerators, the Main Injector and Recycler Ring. During normal operation, high intensity proton beams exist simultaneously in both. The two accelerators share the same beam loss monitors (BLM) and monitoring system. Deciphering the origin of any of the 260 BLM readings is often difficult. The (Accelerator) Real-time Edge AI for Distributed Systems project, or READS, has developed an AI/ML model, and implemented it on fast FPGA hardware, that disentangles mixed beam losses and attributes probabilities to each BLM as to which machine(s) the loss originated from in real-time. The model inferences are then streamed to the Fermilab accelerator controls network (ACNET) where they are available for operators and experts alike to aid in tuning the machines.

CERN, Meyrin, Switzerland

The Full Remote Alignment System (FRAS) is a complex measurement, alignment and control system designed to remotely align components of the Large Hadron Collider (LHC) following its High Luminosity upgrade. The purpose of FRAS is to guarantee optimal alignment of the strong focusing magnets and associated components near the experimental interaction points, while at the same time limiting the radiation dose to which surveyors in the LHC tunnel are subjected. A failure in the FRAS control system, or an operator mistake, could provoke a non desired displacement of a component that could lead to damage of neighbouring equipment. Such an incident would incur a considerable repair cost both in terms of money and time. To mitigate this possibility, an exhaustive risk analysis of FRAS has been performed, with the design of protection layers according to the IEC 61511 standard proposed. This paper presents the different functional safety techniques applied to FRAS, reports on the current project status, and introduces the future activities to complete the safety life cycle.

The Hybrid Identity of a Control System Organization: Balancing Support, Product, and R&D Expectations

software, framework, operation, experiment

303

S. Baymani
PSI, Villigen PSI, Switzerland

Controls organizations are often expected to fulfill a dual role as both a support organization and an R&D organization, providing advanced and innovative services. This creates a tension between the need to provide services and the desire and necessity to develop cutting-edge technology. In addition, Controls organizations must balance the competing demands of product development, maintenance and operations, and innovation and R&D. These conflicting expectations can lead to neglect of long-term strategic issues and create imbalances within the organization, such as technical debt and lack of innovation. This paper will explore the challenges of navigating these conflicting expectations and the common traps, risks, and consequences of imbalances. Drawing on our experience at PSI, we will discuss specific examples of conflicts and their consequences. We will also propose solutions to overcome or improve these conflicts and identify a long-term, sustainable approach for a hybrid organization such as Controls . Our proposals will cover strategies for balancing support and product development, improving communication, and enabling a culture of innovation. Our goal is to spark a broader discussion around the identity and role of control system organizations within large laboratory organizations, and to provide concrete proposals for organizations looking to balance competing demands and build a sustainable approach to control systems and services.

These are challenging times for research institutes in the field of software engineering. Our designs are becoming increasingly complex, and a software engineer needs years of experience to become productive. On the other hand, the software job market is very dynamic, and a computer engineer receives tens of offers from private companies with attractive salaries every year. Occasionally, the perfect storm can occur, and in a short period of time, several key people in a group with years of experience leave. The situation is even more critical when the institute is plunged into a high growth rate with several new instruments under way. Naturally, engaged teams will resist reducing operational service quality, but, on the other hand, the new installations milestones dates will approach quickly. This article outlines the decision-making process and the measures taken to cope with this situation in the ALBA Synchroton’s Controls Section. The plan included reorganizing teamwork, but more importantly, redefining the relationship with our clients and prioritization processes. As a result, the team was restructured and new roles were created. In addition, effective coordination was vital, and new communication channels were established to ensure smooth workflows. The emergency peak period is over in our case, but we have learned a lot of lessons and implemented many changes that will stay with us. They have made us more efficient and more resilient in case of future emergencies.

The CERN Accelerator Controls systems have to remain as stable as possible for operations. However, there are inevitable needs to introduce changes to provide new functionalities and conduct important consolidation activities. To deal with this, a formal procedure and approval process, the Smooth Upgrades procedure, was introduced and refined over a number of years. This involves declaring foreseen Controls changes as a function of the accelerator schedules, validating them with stakeholders, and organising their deployment in the production environment. All of this with the aim of minimising the impact on accelerator operation. The scope of this activity is CERN-wide, covering changes developed by all CERN units involved in Controls and encompassing the whole CERN accelerator and facility complex. In 2022, the mandate was further extended with a more formal approach to coordinate changes of the software interfaces of the devices running on front-end computers, which form a critical part of the smooth deployment process. Today, Smooth Upgrades are considered a key contributor to the performance and stability of the CERN Control system. This paper describes the Smooth Upgrades procedure and the underlying processes and tools such as schedule management, change management, and the monitoring of device usage. The paper also includes the major evolutions which allowed the current level of maturity and efficiency to be reached. Ideas for future improvements will also be covered.

Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
At the National Ignition Facility (NIF), achieving fusion ignition for the first time ever in a laboratory required one of the most complex hardware control systems in the world. With approximately 1,200 control racks, 66,000 control points, and 100, 000 cables, maintaining the NIF control system requires an exquisite choreography around experimental operations while adhering to NIF’s safety, security, quality, and efficiency requirements. To ensure systems operate at peak performance and remain available at all times to avoid costly delays, preventative maintenance activities are performed two days per week as the foundation of our effective maintenance strategy. Reactive maintenance addresses critical path issues that impact experimental operations through a rapid response 24x7 on-call support team. Prioritized work requests are reviewed and approved daily by the facility operations scheduling team. NIF is now in the second decade of operations, and the aging of many control systems is threatening to affect performance and availability, potentially impacting planned progress of the fusion ignition program. The team is embarking on a large-scale refurbishment of systems to mitigate this threat. Our robust maintenance program will ensure NIF can capitalize on ignition and push the facility to even greater achievements. This paper will describe the processes, procedures, and metrics used to plan, coordinate, and perform controls hardware maintenance at NIF.

As part of the effort to standardize the control system environment of ITER’s in-kind delivered >170 plant systems, the Controls Division publishes CODAC Core System (CCS), a complete Linux-based control system software distribution. In the past, a large part of the integrated and end-to-end software testing for CCS was executed manually, using many long and complex test plan documents. As the project progress introduces increasing scope and higher quality requirements, that approach was not maintainable in the long term. ITER CODAC and its partners have started a multi-year effort converting manual tests to automated tests, inside the so-called Framework for Integration Testing (FIT), which itself is being developed and gradually extended as part of the effort. This software framework is complemented by a dedicated hardware test stand setup, comprising specimens of the different controllers and I/O hardware supported by CCS. FIT and the test stand will allow to run fully scripted hardware-in-the-loop (HIL) tests and allow functional verification of specific software modules as well as different end-to-end use cases.

The IRFU*/DIS software control team is involved from feasibility studies to the deployment of equipment covering low level (hardware, PLC) to high level (GUI supervision). For our experiments, we are using two mains frameworks: - MUSCADE, a full Java in-house solution embedded SCADA dedicated to small and compact experiments controlled by PLC (Programmable Logic Controller), only compatible with Windows Operating System (OS) for the server side. - EPICS**, a distributed control systems to operate devices such as particle accelerators, large facilities and major telescopes, mostly deployed on Linux OS environments. EPICS frameworks provides several languages for bindings and server interfaces such as C/C++, Python and Java. However, most of the servers also called IOC*** developed in the community are based on C/C++ and Linux OS System. EPICS also provides extensions developed in Java such as the EPICS Archiver Appliance, Phoebus Control-Studio**** (GUI), and Display Web Runtime (Web Client). All these tools depend on CAJ (a pure Java implementation Channel Access Library). Today, MUSCADE users use to work under Windows, and they need intuitive tools that provide the same features than MUSCADE. Thus, research and development activities mainly focus on EPICS solution adaptation. It aims to explore further CAJ library, especially on the server side aspect. In order to achieve this goal, several developments have been carried out since 2018.

ESS, Lund, Sweden

The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Commissioning of the first part of the accelerator has begun and the requirements on the control system interfaces varies greatly as progress is made and new systems are added. In this paper, three such applications are discussed in separate sections. A Navigator interface was developed for the control room interfaces aimed towards giving operators and users a clear and structured way towards quickly finding the needed interface(s) they need. The construction of this interface is made automatically via a Python-based application and is built on applications in any directory structure both with and without developer interference (fully and semi-automatic methods). The second interface discussed in this paper is the Operations Accelerator Synoptic interface, which uses a set of input lattices and system interface templates to construct configurable synoptic view of the systems in various sections and a controller panel for any selected system. Lastly for this paper there is a configurable Radio Frequency Orchestration interface for Operations, which allows in-situ modification of the interface depending on which systems and components are selected.

The Phoebus user interface to EPICS is an integral part of the new control system for the ISIS Neutron and Muon Source accelerators and targets. Phoebus can use the EPICS Archiver Appliance, which has been deployed as part of the transition to EPICS, to display the history of PVs. However, ISIS data has and continues to be stored in the InfluxDB time series database. To enable access to this data, a Python application to interface between Phoebus and other databases has been developed. Our implementation utilises Quart, an asynchronous web framework, to allow multiple simultaneous data requests. Google Protocol Buffer, natively supported by Phoebus, is used for communication between Phoebus and the database. By employing subclassing, our system can in principle adapt to different databases, allowing flexibility and extensibility. Our open-source approach enhances Phoebus’s capabilities, enabling the community to integrate it within a wider range of applications.

A robust monitor and control front-end application is a crucial feature for large and scalable radio telescope infrastructures such LOFAR and SKA, whereas the control system is required to manage numerous attribute values at a high update rate, and thus the operators must rely on an affordable user-interface platform which covers the whole range of operations. In this paper two state-of-the-art web applications such Grafana and Taranta are taken into account, developing a comparative analysis between the two software suites. Such a choice is motivated mostly because of their widespread use together with the TANGO Controls Framework, and the necessity to offer a ground of comparison for large projects dealing with the development of a monitor and control GUI which interfaces to TANGO. We explain at first the general architecture of both systems, and then we create a typical use-case where an interactive dashboard is built to monitor and control a hardware device. Then, we set up some comparable metrics to evaluate the pros and cons of both platforms, regarding the technical and operational requirements, fault tolerances, developers and operators efforts, and so on. In conclusion, the comparative analysis and its results are summarized with the aim to offer the stakeholders a basis for future choices.

For more than a decade, the Eclipse-based Control System Studio has provided FRIB with a rich user interface to its EPICS-based control system. At FRIB, we use the Alarm Handler, BOY Display Manager, Scan Monitor/Editor, Channel Client, Save-and-Restore, and Data Browser to monitor and control various parts of the beamline. Our engineers have developed over 3000 displays using the BOY display manager mapping various segments and areas of the FRIB beamline. CS-Studio Phoebus is the latest next-generation upgrade to the Eclipse-based CS-Studio, which is based on the modern JavaFX-based graphics and aims toward providing existing functionalities and more. FRIB has already transitioned away from the old BEAST alarm servers to the new Kafka-based Phoebus alarm servers which have been monitoring thousands of our EPICS PVs with its robust monitoring and notifying capabilities. We faced certain challenges with conversion of FRIB’s thousands of displays and to address those we deployed scripts to help the bulk conversion of screens with automated mapping between BOY and Display Builder and also continually improved the Phoebus auto-conversion tool. This paper details the ongoing transition of FRIB from Eclipse-based CS-Studio to Phoebus and various adaptations and solutions that we used to ease this transition for our users. Moving to the new Phoebus-based services and client have provided us with an opportunity to rectify and improve on certain issues known to have existed with Eclipse-based CS-Studio and its services.

Multi-Dimensional Spectrogram Application for Live Visualization and Manipulation of Large Waveforms

368

ESS, Lund, Sweden

The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Protons are accelerated via cavity fields through various accelerating structures that are powered by Radio-Frequency (RF) power. As the cavity fields may break down due to various reasons, usually post-mortem data of such events contain the information needed regarding the cause. In other events, the underlying cause may have been visible on previous beam pulses before the interlock triggering event. The Multi-Dimensional Spectrogram Application is designed to be able to collect, manipulate and visualize large waveforms at high repetition rates, with the ESS goal being 14 Hz, for example cavity fields, showing otherwise unnoticed temporary breakdowns that may explain the sometimes-unknown reason for increased power (compensating for those invisible temporary breakdowns). The first physical event that was recorded with the tool was quenching of a superconducting RF cavity in real time in 3D. This paper describes the application developed using Python and the pure-python graphics and GUI library PyQtGraph and PyQt5 with Python-OpenGL bindings.

Ultra-intense laser-plasma interactions can produce TV/m acceleration gradients, making them promising for compact accelerators. Peking University is constructing a proton radiotherapy system prototype based on PW laser accelerators, but transient processes challenge stability control, critical for medical applications. This work demonstrates artificial intelligence’s (AI) application in laser accelerator control systems. To achieve micro-precision alignment between the ultra-intense laser and target, we propose an automated positioning program using the YOLO algorithm. This real-time method employs a convolutional neural network, directly predicting object locations and class probabilities from input images. It enables precise, automatic solid target alignment in about a hundred milliseconds, reducing experimental preparation time. The YOLO algorithm is also integrated into the safety interlocking system for anti-tailing, allowing quick emergency response. The intelligent control system also enables convenient, accurate beam tuning. We developed high-performance virtual accelerator software using "OpenXAL" and GPU-accelerated multi-particle beam transport simulations. The software allows real-time or custom parameter simulations and features control interfaces compatible with optimization algorithms. By designing tailored objective functions, desired beam size and distribution can be achieved in a few iterations.

The electronic logbook (elog) system used at Brookhaven National Laboratory’s Collider-Accelerator Department (C-AD) allows users to customize logbook settings, including specification of favorite logbooks. Using machine learning techniques, customizations can be further personalized to provide users with a view of entries that match their specific interests. We will utilize natural language processing (NLP), optical character recognition (OCR), and topic models to augment the elog system. NLP techniques will be used to process and classify text entries. To analyze entries including images with text, such as screenshots of controls system applications, we will apply OCR. Topic models will generate entry recommendations that will be compared to previously tested language processing models. We will develop a command line interface tool to ease automation of NLP tasks in the controls system and create a web interface to test entry recommendations. This technique will create recommendations for each user, providing custom sets of entries and possibly eliminate the need for manual searching.

The AGOR cyclotron began development in the late 1980s and was commissioned in 1997. In 2020, when the facility was transferred from the University of Groningen to the University Medical Center Groningen, it marked the start of an upgrade process aimed at ensuring reliable operation. Recent, current and upcoming upgrades and additions encompass the following: Firstly, the current OT network uses custom IO modules based on the outdated Bitbus fieldbus. A pilot study was conducted to evaluate the use of NI CompactRIO-based subracks for analog and digital IO. Also, a similar PLC-based solution is currently under investigation. Secondly, the current control system is based on Vsystem/Vista and alternatives are being investigated. Thirdly, PLCs are upgraded to a newer generation. Fourthly, the current harp electronics and beam current readout electronics both use components that are hard to procure and use a Bitbus interface. New, in-house designs constructed as generic I-V converters eliminate this fieldbus dependency. Fifthly, the present RF slow control employs feedback loops to regulate the RF power and phase. Our new design incorporates functional improvements and condenses several discrete modules into a single cassette, resulting in fewer expected issues with faulty cables and connectors, and enabling us to maintain a larger stock of spares. Finally, the UMCG Radiotherapy department is constructing a new beamline with support from the technical staff at UMCG-PARTREC. The control will be based on NI CompactRIO.

With multiple beamlines and experimental stations completed and in steady use, the facility is now approaching the third phase of development, which includes the final two of the 16 planned beamlines in user operation. The focus is on achieving operational excellence by optimizing reliability and performance. Meanwhile, the strategy for the coming years is driven by the need to accommodate a growing user base, exploring the possibility of operating a Soft X-ray Laser (SXL), and achieving the diffraction limit for 10 keV of the 3 GeV. The Technical Division is responsible for the control and computing systems of the entire laboratory. This new organization provides a coherent strategy and a clear vision, with the ultimate goal of enabling science. The increasing demand for more precise and efficient control systems has led to significant developments and maintenance efforts. Pushing the limits in remote access, data generation, time-resolved and fly-scan experiments, and beam stability requires the proper alignment of technology in IT infrastructure, electronics, software, data analysis, and management. This article discusses the motivation behind the updates, emphasizing the expansion of the control system’s capabilities and reliability. Lastly, the technological strategy will be presented to keep pace with the rapidly evolving technology landscape, ensuring that MAX IV is prepared for its next major upgrade.

Fermilab, Batavia, Illinois, USA

Modernizing the Fermilab accelerator control system is essential to future operations of the laboratory’s accelerator complex. The existing control system has evolved over four decades and uses hardware that is no longer available and software that uses obsolete frameworks. The Accelerator Controls Operations Research Network (ACORN) Project will modernize the control system and replace end-of-life power supplies to enable future accelerator complex operations with megawatt particle beams. An overview of the ACORN Project will be presented along with a summary of recent R&D activities.

Operational since 2008, SOLEIL [1] is providing users with access to a wide range of experimental techniques thanks to its 29 beamlines, covering a broad energy range from THz to hard X-ray. In response to new scientific and societal challenges, SOLEIL is undergoing a major transformation with the ongoing SOLEIL II project. This project includes designing an ambitious Diffraction Limited Storage Ring (DLSR) [2] to increase performances in terms of brilliance, coherence, and flux, upgrading the beamlines to provide advanced methods, and driving a digital transformation in data- and user- oriented approaches. This paper presents the project organization and technical details studies for the ongoing upgrades, with a focus on the digital transformation required to address future scientific challenges. It will depict the computing and data management program with the presentation of the targeted IT architecture to improve automated and data-driven processes for optimizing instrumentation. The optimization program covers the facility reconstruction period as well as future operation, including the use of Artificial Intelligence (AI) techniques for data production management, decision-making, complex feedbacks, and data processing. Real-time processes are to be applied in the acquisition scanning design, where detectors and robotic systems will be coupled to optimize beam time.

Future generations of Beam Instrumentation systems will be based on Multiprocessor System on Chip (MPSoC) technology. This new architecture will allow enhanced exploitation of instrumentation signals from CERN’s accelerator complex, and has thus been chosen as the next platform for several emerging systems. One of these systems, for the HL-LHC BPM (High-Luminosity LHC Beam Position Monitors), is currently at a prototyping stage, and it is planned to test this prototype with signals from real monitors in CERN’s accelerators during 2023. In order to facilitate the analysis of the prototype’s performance, a strategy to integrate the setting, control and data acquisition within CERN’s accelerator control system has been developed. This paper describes the exploration of various options and eventual choices to achieve a functional system, covering all aspects from data acquisition from the gateware, through to eventual logging on the accelerator logging database. It also describes how the experiences of integrating this prototype will influence future common strategies within the accelerator sector, highlighting how specific problems were addressed, and quantifying the performance we can eventually expect in the final MPSoC-based systems.

The Laser MegaJoule (LMJ), a 176-beam laser French facility, located at the CEA* CESTA close to Bordeaux is part of the French Simulation Program, for improvement of theoretical models, high performance numerical simulations and experimental validations. It is designed to deliver about 1.4 MJ of energy on targets, for plasma and fusion experiments. With 15 bundles operational at the end of 2023, the operational capabilities are increasing gradually until the full completion of the LMJ facility by 2025. With the increasing of the Power Conditioning Modules (PCM), it has been observed more and more instabilities in the synchronization and the repeatability of the PCM’s triggering. For experiments based on 10 or more bundles, it has resulted in the issue of coupling the LMJ bundles with the PETAL laser and in the safety shutdown of the PCM due to the timeout of capacitors under high voltage. In this paper, a description of the LMJ PCM is first given. Then, the considered problem is presented with a detailed analysis and the software solution is finally presented with experimental results showing the gain in the reliability and effectiveness of the PCM during the LMJ-PETAL shots.

The fourth industrial revolution, the current trend of automation and data interconnection in industrial technologies, is becoming an essential tool to boost maintenance and availability for space applications, warehouse logistics, particle accelerators and for harsh environments in general. The main pillars of Industry 4.0 are Internet of Things (IoT), Wireless Sensors, Cloud Computing, Artificial Intelligence (AI), Machine Learning and Robotics. We are finding more and more way to interconnect existing processes using technology as a connector between machines, operations, equipment and people. Facility maintenance and operation is becoming more streamlined with earlier notifications, simplifying the control and monitor of the operations. Core to success and future growth in this field is the use of robots to perform various tasks, particularly those that are repetitive, unplanned or dangerous, which humans either prefer to avoid or are unable to carry out due to hazards, size constraints, or the extreme environments in which they take place. To be operated in a reliable way within particle accelerator complexes, robot controls and interfaces need to be included in the accelerator control frameworks, which is not obvious when movable systems are operating within a harsh environment. In this paper, the operational controls for robots at CERN is presented. Current robot controls at CERN will be detailed and the use case of the Train Inspection Monorail robot control will be presented.

EPICS IOC Integration with Rexroth Controller for a T-Zero Chopper

429

B.K. Krishna, M. Ruiz Rodriguez
ORNL, Oak Ridge, Tennessee, USA

A neutron chopper is not typically used as a filter, but rather as a way to modulate a beam of neutrons to select a certain energy range or to enable time-of-flight measurements. T-Zero neutron choppers have been incorporated into several beamlines at SNS and are operated via a Rexroth controller. However, the current OPC is only compatible with Windows XP, which has led to the continued use of an XP machine to run both the Indradrive (Rexroth interface) and EPICS IOC. This setup has caused issues with integrating with our Data Acquisition server and requires separate maintenance. As a result, for a new beamline project, we opted to switch to the Rexroth XM22 controller with T-Zero chopper, which allows for the use of drivers provided by Rexroth in various programming languages. This paper will detail the XM22 controller drivers and explain how to utilize them to read PLC parameters from the controller into the EPICS application and its Phoebus/CSS interface.

Interruptions in the functioning of linear superconductive accelerators LLRF (Low-Level Radio Frequency) systems can result in significant downtime. This can lead to lost productivity and revenue. Accelerators are foreseen to operate under various conditions and in different operating modes. As such, it is crucial to have flexibility in their operation to adapt to demands. Automation is a potential solution to address these challenges by reducing the need for human intervention and improving the control’s quality over the accelerator. The paper describes EPICS-based tools for LLRF control system testing, optimization, and operations support. The proposed software implements procedures and applications that are usually extensions to the core LLRF systems functionalities and are performed by operators. This facilitates the maintenance of the accelerator and increases its flexibility in adaptation to various work conditions and can increase its availability level. The paper focuses on the architecture of the solution. It also depicts its components related to superconducting cavities parameters identification and elements responsible for their tuning. Since the proposed solution is destined for the European Spallation Source control system, the application has a form of multiple IOCs (Input/Output Controllers) wrapped into E3 (ESS EPICS Environment) modules. Nevertheless, it can be adjusted to other control systems - its logic is universal and applicable (after adaptations) to other LLRF control systems with superconducting cavities.

For some time now, we* have also been using the EPICS** control system in small laboratories in order to be able to guarantee data recording and processing in accordance with the FAIR*** guidelines and thus to increase the overall quality of the data. It was necessary to overcome many reservations and, above all, to counter the prejudice that such systems are only suitable for large-scale installations. We are now trying to communicate the idea behind this kind of data acquisition (distributed systems, open protocols, open file formats, etc.) also in the studies of physicists, chemists and engineers and are extending our activities to universities. We also hope that in the future, users who use the individual user facilities will be able to make optimal use of the options available there. In our talk we will present the use of EPICS in small laboratories.

In modern 4th generation synchrotron facilities, piezo actuators are widely applied due to their nanometric precision in linear motion and stability. This work shows the implementation of a switching control architecture and a tripod kinematics for a set of 4 piezo actuators, responsible by positioning the short-stroke: the vertical and horizontal focusing mirrors of the Kirkpatrick-Baez mirror system at MOGNO Beamline (X-Ray Microtomography). The switching control architecture was chosen to balance timing to move through the working range (changing the beam incidence on stripes of low/high energy), resolution and infrastructure costs. This paper also shows the implementation and results of the developed kinematics by layers that uncouples short-stroke from long-stroke to fix any parasitic displacements that occur on the granite bench levelers due to slippage during the movement and to match the required beam stability without losing alignment flexibility or adjustment repeatability. The architecture was built between a PIMikroMove set of driver-actuators and an Omron Delta Tau Power Brick controller due to its standardization across the control systems solutions at Sirius, ease of control software scalability and its capability to perform calculations and signal switching for control in C language, with real-time performance to make adjustments to the angles responsible by focusing the beam in a speed that matches the required position stability, guaranteeing the necessary resolution for the experiments.

Accelerators and other big science facilities rely heavily on internally developed technologies, including control system software. Much of it can and is shared between labs, like the Tango Controls and EPICS. Then, some of it finds broad application outside science, like the famous World Wide Web. However, there are still a lot of duplicating efforts in the labs, and a lot of software has the potential to be applied in other areas. Increasing collaboration and involving private companies can help avoid redundant work. It can decrease the overall costs of laboratory development and operation. Having private industry involved in technology development also increases the chances of new applications. This can positively impact society, which means effective spending of public funds. The talk will be based on the results of a survey looking at how much scientific institutes and companies focus on collaboration and dissemination in the field of software technologies. It will also include remarks based on the authors’ experiences in building an innovative ecosystem.

CERN, Meyrin, Switzerland

CERN currently houses 6000 handling equipment units categorized into 40 different families, such as electric overhead travelling cranes (EOT), hoists, trucks, and forklifts. These assets are spread throughout the CERN campus, on the surface (indoor and outdoor), as well as in underground tunnels and experimental caverns. Partial access to some areas, a large area to cover, thousands of units, radiation, and diverse needs among handling equipment makes maintenance a cumbersome task. Without automatic monitoring solutions, the handling engineering team must conduct periodic on-site inspections to identify equipment in need of regulatory maintenance, leading to unnecessary inspections in hard-to-reach environments for underused equipment but also reliability risks for overused equipment between two technical visits. To overcome these challenges, a remote monitoring solution was introduced to extend the equipment lifetime and perform optimal maintenance. This paper describes the implementation of a remote monitoring solution integrating IIoT (Industrial Internet of Things) technologies with the existing CERN control infrastructure and frameworks for control systems (UNICOS and WinCC OA). At the present time, over 600 handling equipment units are being monitored successfully and this number will grow thanks to the scalability this solution offers.

Formal verification techniques are widely used in critical industries to minimize software flaws. However, despite the benefits and recommendations of the functional safety standards, such as IEC 61508 and IEC 61511, formal verification is not yet a common practice in the process industry and large scientific installations. This is mainly due to its complexity and the need for formal methods experts. At CERN, the PLCverif tool was developed to verify PLC programs formally. Although PLCverif hides most of the complexity of using formal methods and removes barriers to formally verifying PLC programs, engineers trying to verify their developments still encounter different obstacles. These challenges include the formalization of program specifications or the creation of formal models. This paper discusses how to overcome these obstacles by proposing a collaboration model that effectively allows the verification of critical PLC programs and promotes knowledge transfer between organizations. By providing a simpler and more accessible way to carry out formal verification, tools like PLCverif can play a crucial role in achieving this goal. The collaboration model splits the specification, development, and verification tasks between organizations. This approach is illustrated through a case study between GSI and CERN.

MedAustron is a synchrotron-based ion therapy and research facility in Austria, that has been successfully treating cancer patients since 2016. MedAustron acts as a manufacturer of its own accelerator with a strong commitment to continuous development and improvement for our customers, our users and our patients. The control system plays an integral role in this endeavour. The presented project focuses on replacing the well-established WinCC OA SCADA system, enforcing separation of concerns mainly using .NET and web technologies, along with many upgrades of features and concepts where stakeholders had identified opportunities for improvement during our years of experience with the former control system setup for commissioning, operation and maintenance, as well as improving the user experience. Leveraging our newly developed control system API, we are currently working on an add-on called "Commissioning Worker". The concept foresees the functionality for users to create Python scripts, upload them to the Commissioning Worker, and execute them on demand or on a scheduled basis, making it easy and highly time-efficient to execute tasks and integrate with already established Python frameworks for analysis and optimization. This contribution outlines the key changes and provides examples of how the user experience has been improved.

System Identification via ARX Model and Control Design for a Granite Bench at Sirius/LNLS

LNLS, Campinas, Brazil

Modern 4th generation synchrotron facilities demand mechanical systems and hardware capable of fine position control, improving the performance of experiments at the beamlines. In this context, granite benches are widely used to position systems such as optical elements and magnetos, due to its capacity of insulating interferences from the ground. This work aims to identify the transfer function that describes the motion of the granite bench at the EMA Beamline (Extreme conditions Methods of Analysis) and then design the control gains to reach an acceptable motion performance in the simulation environment before embedding the configuration into the real system, followed by the validation at the beamline. This improvement avoids undesired behaviour in the hardware or in the mechanism when designing the controller. The bench, weighting 1.2 tons, is responsible by carrying a coil, weighting 1.8 tons, which objective is to apply a 3 T magnetic field to the sample that receives the beam provided by the electrons accelerator. The system identification method applied in this paper is based on the auto-regressive model with exogenous inputs (ARX). The standard servo control loop of the Omron Delta Tau Power Brick controller and the identified plant were simulated in Simulink in order find the control parameters. This paper shows the results and comparison of the simulations and the final validation of the hardware performance over the real system.

Improvements on Kinematics and Control of Granite Benches at LNLS-Sirius

At the Brazilian Synchrotron Light Laboratory, the radiation beam is conditioned by optical elements that must be positioned with high stability and precision. Many of the optical elements are positioned using granite benches that provide high coupling stiffness to the ground and position control in up to six degrees of freedom, using a set of stepper motors. The solution of the inverse kinematics was done numerically by the Newton Raphson method. By employing the property that these systems have small rotation angles, the Jacobian matrix used in this numerical method can be simplified to reduce computational execution time and allow high processing rates. This paper also shows the results of adding a notch filter to the position servo control loop of the granite benches to increase stability due to their mass-spring-damper characteristics. The kinematics and control of the granite benches are implemented in an Omron Power Brick LV controller, with the kinematics developed in MATLAB and the C-code generated by MATLAB C-Coder. Reducing the execution time of the kinematics improves the efficient use of the computational resources and allows the real-time clock rate to be increased.

LNLS, Campinas, Brazil

The development of innovative model-based design high bandwidth mechatronic systems with stringent performance specifications has become ubiquitous at LNLS-Sirius beamlines. To achieve such unprecedent specifications, closed loop control architecture must be implemented in a fast, flexible and reliable platform such as NI CompactRIO (cRIO) controller that combines FPGA and real-time capabilities. The design phase and life-cycle management of such mechatronics systems heavily depends on high quality experimental data either to enable rapid prototyping, or even to implement continuous improvement process during operation. This work aims to present and compare different techniques to stimulus signal generation approaching Schroeder phasing and Tukey windowing for better crest factor, signal-to-noise ratio, minimum mechatronic stress, and plant identification. Also show the LabVIEW implementation to enable embeddeding this framework that requires specific signal synchronization and processing on the main application containing a hardware-based control architecture, increasing system diagnostic and maintenance ability. Finally, experimental results from the High-Dynamic Double-Crystal Monochromator (HD-DCM-Lite) of QUATI (quick absorption spectroscopy) and SAPUCAIA (small-angle scattering) beamlines and from the High-Dynamic Cryogenic Sample Stage from SAPOTI (multi-analytical X-ray technique) of CARNAÚBA beamline are also presented in this paper.

For 10 years our Institute CEA Saclay Irfu has been involved in several in-kind collaboration contracts with ESS at Lund (Sweden) and one of these includes the test of numerous cryomodules in a dedicated test bench designed at Saclay. The cryomodules start to be assembled cavity per cavity in a clean room and must be low pressure pumped, without adding particles and always in a clean room. This is the purpose of the mobile pumping units for particle free beam vacuum. These units are also designed for vacuum automatic procedures, residual gas analysis and can provide conformity reports. Furthermore, a connectable industrial touch panel is added for a mobile operator interface. Only few buttons have to be panel touched by an operator to start automatic procedures in order to get a very high quality vacuum. The embedded control system is PLC based and manages many communications, especially with the spectrometer embedded in the unit. Only one CPU manages all the communications (Profinet, Profibus, TCP-IP ASCII and even Modbus) and sensors or actuators are controlled by four input-output cards. This small-scale control system is innovative because it is versatile, very convenient to use, deploy and maintain. Nine mobile pumping units are operational and continuously used, frequently moved to different locations, controlled locally or remotely and are still reliable. The paper describes the control architecture and functionalities of this small but full of possibilities device.

The Laser MegaJoule, a 176-beam laser facility developed by CEA, is located near Bordeaux. It is part of the French Simulation Program, which combines improvement of theoretical models used in various domains of physics and high performance numerical simulation. It is designed to deliver about 1.4 MJ of energy on targets, for high energy density physics experiments, including fusion experiments. The LMJ technological choices were validated on the LIL, a scale-1 prototype composed of 1 bundle of 4-beams. The first bundle of 8-beams was commissioned in October 2014 with the realisation of the first experiment on the LMJ facility. The operational capabilities are increasing gradually every year until the full completion by 2025. By the end of 2023, 18 bundles of 8-beams will be assembled and 15 bundles are expected to be fully operational. In this paper, a presentation of the LMJ Control System architecture is given. A description of the integration platform and simulation tools, located outside the LMJ facility, is given. Finally, a review of the LMJ status report is detailed with an update on the LMJ and PETAL activities.

The LMJ*, a 176-beam laser facility developed by the French Nuclear Science directorate CEA, is located at the CEA** CESTA site near Bordeaux. The LMJ facility is part of the French Simulation Program. It is designed to deliver about 1.4 MJ of energy on targets, for high energy density physics experiments, including fusion experiments. Since 2022, the LMJ facility aims at carrying out experiments with 12 bundles of 8 laser beams and 12 target diagnostics. In order to achieve daily shots including all the preparatory steps, the LMJ performs night activities from now on and the presence of technical operators is not required. These sequences work on vacuum windows inspection and beam alignment. They take into account all the prerequisites for their good performances and are scheduled automatically one after the other. They deal with material security and unexpected equipment alarms. They endeavour to required tasks success and give a detailed report of the night events to the shot director. This paper gives a presentation of the two sequences with solutions in order to answer the technical specifications and the last enhancements.

Apollon, LULI2000 and HERA are three Research Infrastructures of the Centre national de la recherche scientifique (CNRS), École polytechnique (X), Commissariat à l’Énergie Atomique et aux Energies Alternatives (CEA) and Sorbonne University (SU). Now in past-commissioning phase, Apollon is a four beam laser, multi-petawatt laser facility fitted with instrumentation technologies on the cutting edge with two experimental areas (short–up to 1m–and long focal–up to 20m, 32m in the future). To monitor the laser beam characteristics through the interaction chambers, more than 300 devices are distributed in the facility and controlled through a Tango bus. This poster presents primarily a synthetic view of the Apollon facility, from network to hardware and from virtual machines to software under Tango architecture. We can here have an overview of the different types of devices which are running on the facility and some GUIs developed with the exploitation team to insure the best possible way of running the lasers. While developments are still currently under work for this facility, upgrading the systems of LULI2000 from one side and HERA from the other side are underway by the Control-Command & Supervision team and would follow the same specifications to offer shared protocols and knowledge.

HZB, Berlin, Germany

Continuous energy scanning is an important feature for many beamlines at BESSY II. In 2015 this method was used at 11 Undulator and 6 dipol beamlines.[1] Since then the demand for this feature - especially among new build beamlines - increased, while the availability of the used hardware decreased. In order to tackle this problem, we investigate into alternative solutions for both, hardware and software. By introducing an independent high level controller between the two device controllers, we can compensate for communication incompatibilities and hence increase flexibility. This paper shows the status of our research. The ideas leading to a first prototype, the prototype itself and first results will be presented.

Considering the existing Bluesky control framework at BESSY II, a web client with React based on Bluesky HTTP Server is being developed. We hope to achieve a cross-platform and cross-device system to realize remote control and monitoring of experiments. The current functions of the system are monitoring of the Bluesky Queue Server status, control over a Bluesky Run Engine environment, browsing of Queue Server history and editing and running of Bluesky plans. Challenges around the presentation of live data are explored. This work builds on that of NSLS II who created a React based web interface and implements a tool for BESSY II.

HZB, Berlin, Germany

To maximize beamtime usage motorization of beamline equipment is crucial. Choosing the correct motor is complex, since performance depends largely on the combination of motor and motion controller [1]. This challenge, alongside renewing the twenty years old infrastructure at BESSY II, led to the demand for a motor testbench. The testbench was designed to be modular, so it fits different motors, loads and sensors. It allows independent performance verification and enables us to find a fitting combination of motor and motion controller. The testbench is operated via EPICS and Bluesky, allowing us usage of python for automated data acquisition and testing. An overview of the mechanical and electrical setup, as well as some data from different performance tests will be presented.

HZB, Berlin, Germany

The BESSY II lightsource has been in operation at Helmholtz-Center Berlin (HZB) for 25 years and is expected to be operated for more than the next decade. The EPICS Alarm Handler (alh) has served as the basis for a reliable alarm system for BESSY II as well as other facilities and laboratories operated by HZB. To preempt software obsolescence and enable a centralized architecture for other Alarm Handlers running throughout HZB, the alarm system is being migrated to the alarm-service developed within the Control System Studio/Phoebus ecosystem. To facilitate operation of the Alarm Handler, while evaluating the new system, tools were developed to automate creation of the Phoebus alarm-service configuration files in the control systems’ build process. Additionally, tools and configurations were devised to mirror the old system’s key features in the new one. This contribution presents the tools developed and the infrastructure deployed to use the Phoebus alarm-service at HZB.

About the New Linear Accelerator Control System at GSI

operation, timing, linac, software

529

P. Gerhard
GSI, Darmstadt, Germany

The first accelerator at GSI, UNILAC, went into operation in the early 1970s. Today, UNILAC is a small accelerator complex, consisting of several ion sources, injector and main linacs comprising 23 RF cavities, several strippers and other instrumentation, serving a number of experimental areas and the synchrotron SIS18. Three ion species can be provided at different energies simultaneously in a fast time multiplex scheme, two at a time. The UNILAC is going to be the heavy ion injector linac for FAIR, supported by a dedicated proton linac. The current linac control system dates back to the 1990s. It was initiated for SIS18 and ESR, which enlarged GSI at the time, and was retrofitted to the UNILAC. The linear decelerator HITRAP was added in the last decade, while an sc cw linac is under development. Today, SIS18, ESR and lately CRYRING are already operated by a new system based on the LHC Software Architecture LSA, as FAIR will be. In order to replace the outdated linac control system and simplify and unify future operation, a new control system on the same basis is being developed for all GSI linacs. This contribution reports about this venture from a machine physicist point of view.

Running a CW electron accelerator as a user facility for more than two decades necessitates upgrades or even complete redesign of subsystems at some point. At ELBE, the outdated timing system needed a replacement due to obsolete components and functional limitations. Starting in 2019, with Cosylab as contractor and using hardware by Micro Research Finland, the new timing system has been developed and tested and is about to become operational. Besides the ability to generate a broader variety of beam patterns from single pulse mode to 26 MHz CW beams for the two electron sources, one of the benefits of the new system is improved machine safety. The ELBE control systems is mainly based on PLCs and industrial SCADA tools. This contribution depicts how the timing system implementation to the existing machine entailed extensions and modifications of the ELBE machine protection system, i.e. a new core MPS PLC, and how they are being realized.

The Dresden Advanced Light Infrastructure (DALI) is part of the German national Helmholtz Photon Science Roadmap. It will be a high-field source of intense terahertz radiation based on accelerated electrons and the successor of the Center for High-Power Radiation Sources (ELBE) operated at HZDR since 2002. In the current phase of DALI the conceptional design report is in preparation and there are ongoing considerations which control system to use best. We will present the status of those considerations, that include defining the requirements for the control system and a discussion of control system candidates. In the early conceptional phase we are still open to any control system that can fulfill our requirements. Besides pure technical performance, features and security the requirements encompass modernity, well established support by community and companies, long term availability as well as collaboration potential and benefit. To collect opinions from the community on what is the optimal control system we prepared a survey. Like that we would like to benefit as much as possible from the community experience with different types of control systems.

This presentation will showcase our experience in board bring-up using our FPGA Framework and ChimeraTK, our C++ hardware abstraction library. The challenges involved in working with different FPGA vendors will be discussed, as well as how the framework and library help to abstract vendor-specific details to provide a consistent interface for applications. Our approach to integrating this framework and libraries with Yocto, a popular open-source project for building custom Linux distributions, will be discussed. We will show how we leverage Yocto’s flexibility and extensibility to create a customized Linux image that includes our FPGA drivers and tools, and discuss the benefits of this approach for embedded development. Finally, we will share some of our best practices for board bring-up using our framework and library, including tips for debugging and testing. Our experience with FPGA-based board bring-up using ChimeraTK and Yocto should be valuable to anyone interested in developing embedded systems with FPGA technology

The COSY (COoler SYncchrotron) at the Forschungszentrum Jülich is a hadron accelerator build in the early 90s, with work started in the late 80s. At this time the whole control system was based on a self-developed real-time operating system for Motorola m68k boards, utilizing, unusual for this time, IP-networks as transport layer. The GUI was completely based on Tcl/Tk. After 25 years of operation, in 2016, it was decided to upgrade the control system to EPICS and the GUI to CS-Studio, in order to e.g. allow a better automatization or automatized archiving of operational parameters. This was done together with Cosylab d.d. bit by bit while the synchrotron was in operation, and because of the complexity is still ongoing. The experiences of the stepwise upgrade process will be presented and a lessons learned will be emphasized.

In the Jülich High Brilliance Neutron Source (HBS) project Forschungszentrum Jülich is developing a novel High Current Accelerator-driven Neutron Source (HiCANS) that is competitive to medium-flux fission-based research reactors or spallation neutron sources. The HBS will include a 70 MeV linear accelerator which delivers a pulsed proton beam with an average current of 100 mA to three target stations. At each target station the average power will be 100 kW generating neutrons for at least six neutron instruments. The concept for the control system has been developed and published in the HBS technical design report. Main building blocks of the control system will be Control System Studio, EPICS and Siemens PLC technology (for vacuum, motion, personnel protection…). The timing system will be based on commercially available components from Micro-Research Finland. The accelerator LLRF will rely on MTCA.4 developments of DESY that are commercially available, too. A small fraction of the control system has already been implemented for the new JULIC neutron platform, which is an HBS target station demonstrator that has been developed at the existing JULIC cyclotron at Forschungszentrum Jülich.

Tuning particle accelerators is not straightforward, as they depend on a large number of non-linearly correlated parameters that, for example, drift over time. In recent years advanced numerical optimization tools have been developed to assist human operators in tuning tasks. A proper interface between the optimizers and the control system will encourage their daily use by the accelerator operators. In this contribution, we present our latest progress in integrating an optimizer framework into the control system of the KARA storage ring at KIT, allowing the automatic tuning methods to be applied for routine tasks.

Model Predictive Control (MPC) is an advanced method of process control whereby a model is developed for a real-life system and an optimal control solution is then calculated and applied to control the system. At each time step, the MPC controller uses the system model and system state to minimize a cost function for optimal control. The Karabo SCADA Framework is a distributed control system developed specifically for European XFEL facility, consisting of tens of thousands of hardware and software devices and over two million attributes to track system state. This contribution describes the application of the Python MPC Toolbox within the Karabo SCADA Framework to solve a monochromator temperature control problem. Additionally, the experiences gained in this solution have led to a generic method to apply MPC to any group of Karabo SCADA devices.

The Elettra Synchrotron, located in Italy near Trieste, has been operating for users since 1994 being the first third generation light source for soft X-rays in Europe. To stay competitive for world-class photon science, a massive upgrade of the storage ring has been planned in 2025. The goal is to build an ultra-low emittance light source with ultra-high brilliance in the same building as the present storage ring. The downtime for installation and commissioning of Elettra 2.0 will last 18 months. In this plan, 20 of the present beamlines should be upgraded and 12 new beamlines are scheduled to be built. In this scenario, also the original beamline interlock and personnel safety systems are going to be upgraded using state of the art technologies. Siemens PLCs will be used for low level control, while higher level applications will be developed using the Tango framework. This work presents and describes the architecture of the future Elettra 2.0 beamline control system named GeCo, Gestione e Controllo in italian.

INFN/LNL, Legnaro (PD), Italy

The vacuum system of ALPI (Acceleratore Lineare Per Ioni) accelerator at LNL (Laboratori Nazionali di Legnaro), including around 40 pumping groups, was installed in the 90s. The control and supervision systems, composed by about 14 control racks, were developed in the same period by an external company, which produced custom solutions for the HW and SW parts. Control devices are based on custom PLCs, while the supervision system is developed in C and C#. The communication network is composed of multiple levels from serial standard to Ethernet passing true different devices to collect the data. The obsolescence of the hardware, the rigid system infrastructure, the deficit of spares parts and the lack of external support, impose a complete renovation of the vacuum system and relative controls. In 2022 the legacy high level control system part was substituted with a new one developed in EPICS (Experimental Physics and Industrial Control System) and CSS (Control System Studio)*. After that, we started the renovation of the HW part with the installation and integration of two new flexible and configurable low level control system racks running on a Siemens PLC and exploiting serial server to control the renewed pumping groups and pressure gauges. The plan for the next years is to replace the legacy hardware with new one retrieving spare parts, provide service continuity, improve PLC software and extend the EPICS control system with new features. This paper describes the adopted strategy and the upgrade status.

INFN/LNL, Legnaro (PD), Italy

Preliminary activities were performed to verify the feasibility of Virtual Reality (VR) and Augmented Reality (AR) technologies applied to nuclear physics laboratories, using them for different purposes: scientific dissemination events, data collection, training, and machine maintenance*. In particular, this last field has been fascinating since it lets developers discover the possibility of redesigning the concept of the Human-Machine Interface. Based on the experience, it has been natural to try to provide to the final user (such as system operators and maintainers) with all the set of information describing the machine and control system parameters. For this reason, we tried to integrate the accelerator’s control system environment and VR/AR application. In this contribution, the integration of an EPICS-based control system and VR environment will be described.

RFX-mod2, currently under construction at Consorzio RFX, is an evolution of the former RFX-mod experiment, with an improved shell and a larger set of electromagnetic sensors. This set, including 192 saddle coils, allows exploring a wide range of plasma control schemas, but at the same time poses a challenge for its Control and Data Acquisition System (CODAS). RFX-mod2 CODAS is required to provide the high-speed acquisition of a large set of signals and their inclusion in the Plasma Control System that must provide a sub-millisecond response to plasma instabilities. While brand new solutions are provided for the acquisition of the electromagnetic signals, involving Zynq-based ADC devices, other parts of the CODAS system have been retained from the former RFX-mod CODAS. The paper presents the solutions adopted in the new RFX-mod2 CODAS, belonging to three main categories: 1) Plasma Real-Time control, including both hardware solutions based on Zynq and the integration of data acquisition and real-time frameworks for its software configuration. For this purpose, MDSplus and MARTe2, two frameworks for data acquisition and real-time control, respectively, have been adopted, which are widely used in the fusion community. 2) Data acquisition, including upgrades performed to the former cPCI-based systems and new ad-hoc solutions based on RedPitaya. 3) Plant supervision, carried out in WinCC-OA and integrated with the data acquisition system via a new WinCC-OA database plugin.

Tokamaks use heating neutral beam (HNB) injectors to reach fusion conditions and drive the plasma current. ITER, the large international tokamak, will have three high-energy, high-power (1MeV, 16.5MW) HNBs. MITICA, the ITER HNB prototype, is being built at the ITER Neutral Beam Test Facility, Italy, to develop and test the ITER HNB, whose requirements are far beyond the current HNB technology. MITICA operates in a pulsed way with pulse duration up to 3600s and 25% duty cycle. It requires a complex control and data acquisition system (CODAS) to provide supervisory and plant control, monitoring, fast real-time control, data acquisition and archiving, data access, and operator interface. The control infrastructure consists of two parts: central and plant system CODAS. The former provides high-level resources such as servers and a central archive for experimental data. The latter manages the MITICA plant units, i.e., components that generally execute a specific function, such as power supply, vacuum pumping, or scientific parameter measurements. CODAS integrates various technologies to implement the required functions and meet the associated requirements. Our paper presents the CODAS requirement and architecture based on the experience gained with SPIDER, the ITER full-size beam source in operation since 2018. It focuses on the most challenging topics, such as synchronization, fast real-time control, software development for long-lasting experiments, system commissioning, and integration.

Taranta is a software suite for generating graphical interfaces for Tango Controls software, currently adopted by MaxIV for scientific experiment usage, SKA during the current construction phase for the development of engineering interfaces for device debugging, and other institutions. A key feature of Taranta is the ability to create customizable dashboards without writing code, making it easy to create and share views among users by linking the dashboards to their own tango devices. However, due to the simplicity and capabilities of Taranta’s widgets, more and more users are creating complex dashboards, which can cause client-side resource problems. Through an analysis of dashboards, we have found that excessive memory requests are generated by a large amount of data. In this article, we report on the process we believe will help us solve this performance issue. Starting with an analysis of the existing architecture, the issues encountered, and performance tests, we identify the causes of these problems. We then study a new architecture exploiting all the potential of the Javascript framework React on which Taranta is built, before moving on to implementation of the solution.

KEK, Ibaraki, Japan

The electron and positron accelerator complex at KEK offers unique experimental opportunities in the fields of elementary particle physics with SuperKEKB collider and photon science with two light sources. In order to maximize the experimental performances at those facilities the injector LINAC employs pulse-to-pulse modulation at 50 Hz, injecting beams with diverse properties. The event-based control system effectively manages different beam configurations. This injection scheme was initially designed 15 years ago and has been in full operation since 2019. Over the years, quite a few enhancements have been implemented. As the event-based controls are tightly coupled with microwave systems, machine protection systems and so on, their modifications require meticulous planning. However, the diverse requirements from particle physics and photon science, stemming from the distinct nature of those experiments, often necessitate patient negotiation to meet the demands of both fields. This presentation discusses those operational aspects of the multidisciplinary facility.

The Upgrade of Pulsed Magnet Control System Using PXIe Devices at KEK LINAC

EPICS, linac, real-time, operation

D. Wang, M. Satoh
KEK, Ibaraki, Japan

In the KEK electron-positron injector LINAC, the pulsed magnet control system modulates the magnetic field at intervals of 20 ms, enabling simultaneous injection into four distinct target rings: 2.5 GeV PF, 6.5 GeV PF-AR, 4 GeV SuperKEKB LER, and 7 GeV SuperKEKB HER. This system operates based on a trigger signal delivered from the event timing system. Upon the receiving specified event code, the PXI DAC board outputs a waveform to the pulse driver, which consequently determines the current of the pulsed magnet. The combination of Windows 8.1 and LabVIEW was utilized to implement the control system since 2017. Nonetheless, due to the cessation of support for Windows 8.1, a system upgrade has become imperative. To address this, Linux has been selected as a suitable replacement for Windows and the EPICS driver for PXIe devices is thus required. This manuscript introduces the development of the novel Linux-based pulsed magnet control system.

The accelerator control system of the J-PARC MR started operation in 2008. Most of the components of the control computers, such as servers, disks, operation terminals, front-end computers and software, which were introduced during the construction phase, have gone through one or two generational changes in the last 15 years. Alongside, the policies for the operation of control computers have changed. This paper reviews the renewal of those components and discusses the philosophy behind the configuration and operational policy. It is also discusses the approach to matters that did not exist at the beginning of the project, such as virtualization or cyber security.

We have been operating the beam interlock system (BIS) for machine protection of the RIKEN RI Beam Factory (RIBF) since 2006. It stops beams approximately 15 ms after receiving an alert signal from the accelerator and beam line components. We continue to operate BIS successfully; however, we are currently developing a successor system to stop a beam within 1 ms considering that the beam intensity of RIBF will continue to increase in the future. After comparing multiple systems, CompactRIO, a product by National Instruments, was selected for the successor system. Interlock logic for signal input/output is implemented on the field-programmable gate array (FPGA) because fast processing speed is required. On the other hand, signal condition setting and monitoring do not require the same speed as interlock logic. They are implemented on the RT-OS and controlled by using experimental physics and industrial control system (EPICS) by setting up an EPICS server on the RT-OS. As a first step in development, a prototype consisting of two stations that handle only digital alert signals was developed and installed in part of the RIBF in the summer of 2022 (224 input contacts). The signal response time of the prototype, measured with an oscilloscope, averaged 0.52 ms with both stations (the distance between two stations is approximately 75 m). Furthermore, by additionally installing a pull-up circuit at each signal input contact of the system, the system response time was successfully reduced to approximately 0.13 ms.

PAL, Pohang, Republic of Korea

The PAL-XFEL beamlines are composed of two different types of beamlines: a hard X-ray beamline and a soft X-ray beamline. The hard X-ray beamline generates free electron lasers with pulse energies ranging from 2-15 keV, pulse lengths of 10-35 fs, and arrival time errors of less than 20 fs from 4-11 GeV electron beams for X-ray Scattering & Spectroscopy (XSS) and Nano Crystallography & Coherent Imaging (NCI) experiments. On the other hand, the soft X-ray beamline generates free electron lasers with photon energies ranging from 0.25-1.25 keV, and with more than 10¹² photons, along with 3 GeV electron beams for soft X-ray Scattering & Spectroscopy (SSS) experiments. To conduct experiments using the XFEL, precise beam alignment, diagnostics, and control of experimental devices are necessary. The devices of the three beamlines are composed of control systems based on the Experimental Physics and Industrial Control System (EPICS), which is a widely-used open-source software framework for distributed control systems. The beam diagnostic devices include QBPM (Quad Beam Position Monitor), photodiode, Pop-in monitor, and inline spectrometer, among others. Additionally, there are other systems such as CRL (Compound Refractive Lenses), KB mirror (Kirkpatrick-Baez mirror), attenuator, and vacuum that are used in the PAL-XFEL beamlines. We would like to introduce the control system, event timing, and network configuration for PAL-XFEL experiments.

Implementation of External Delay Calculator to MeerKAT

target, interface, software, ion-effects

658

B. Ngcebetsha
SARAO, Cape Town, South Africa

The MeerKAT is an interferometric array made up of 64 dishes that operate as a unit. The very first corrections that must be made to the incoming signal is that of geometric and cable length delays, collectively called "delays". In summary, this is the adjustment of the time of arrival of the signal at the correlator from all 64 antennas, to operate as one instrument. The signal must be recorded at the same time. The MeerKAT correlator has inbuilt a delay correction mechanism, which records and applies these corrections during observation. In this paper we describe how this solution was evolved when ‘katpoint‘(the underlying library to which the delay corrections dependend) had a change in dependencies itself. There were two major changes to ‘katpoint‘ 1) changing from ‘ephem‘ to ‘astropy‘ for time and location calculations of a telescope and celestial bodies, and 2) the move from python2 to python3. Most of the Control and Monitoring(CAM) codebase was still using python2 at the time. Our team had the mamoth task of porting all the codebase from ‘py2‘ to ‘py3‘. This presented unexpected issues, particularly in our case - as we wanted to retain Python2 - Python3 backward compatibility. In this paper we explore the challenges faced when ‘katpoint‘ started to implement ‘astropy‘ which is implemented in Python3 whist the rest of our code was still in Python2. The technical benefit of this improvement was an improvement in the astrometry for delay calculations which will improve the MeerKAT science images.

L.P. Williams, R.L. Schwartz
SARAO, Cape Town, South Africa

Funding: National Research Foundation (South Africa)
The MeerKAT radio telescope performs a wide variety of scientific observations. Observation durations range from a few minutes, to many hours, and may form part of observing campaigns that span many weeks. Static observation requirements, such as resources or array configuration, may be determined and verified months in advance. Other requirements however, such as atmospheric conditions, can only be verified hours before the planned observation event. This wide variety of configuration, scheduling and control parameters are managed with features provided by the MeerKAT software. The short term scheduling functionality has expanded from simple queues to support for automatic scheduling (queuing). To support long term schedule planning, the MeerKAT telescope includes an Observation Panning Tool which provides configuration checking as well as dry-run environments that can interact with the production system. Observations are atomized to support simpler specification, facilitating machine learning projects and more flexibility in scheduling around engineering and maintenance events. This paper will provide an overview of observation specification, configuration, and scheduling on the MeerKAT telescope. The support for integration with engineering subsystems is also described. Engineering subsystems include User Supplied Equipment which are hardware and computing resources integrated to expand the MeerKAT telescope’s capabilities.

Funding: South African Radio Astronomy Observatory
The original Controller Area Network (CAN) protocol, was developed for control and monitoring within vehicular systems. It has since been expanded and today, the Open CAN bus protocol is a leading protocol used within servo-control systems for telescope positioning systems. Development of a CAN bus monitoring component is currently underway. This component forms part of a greater software package, designed for an Antenna Positioner Emulator (APE), which is under construction. The APE will mimic movement of a MeerKAT antenna, in both the azimuth and elevation axes, as well as the positioning of the receiver indexer. It will be fitted with the same servo-drives and controller hardware as MeerKAT, however there will be no main dish, sub-reflector, or receiver. The APE monitoring software will receive data from a variety of communication protocols used by different devices within the MeerKAT control system, these include: CAN, Profibus, EnDAT, Resolver and Hiperface data. The monitoring software will run on a BeagleBone Black (BBB) fitted with an ARM processor. Local and remote logging capabilities are provided along with a user interface to initiate the reception of data. The CAN component makes use of the standard SocketCAN driver which is shipped as part of the linux kernel. Initial laboratory tests have been conducted using a CAN system bus adapter that transmits previously captured telescope data. The bespoke CAN receiver hardware connects in-line on the CAN bus and produces the data to a BBB, where the monitoring software logs the data.

Robotic and digitization risks refer to the potential negative consequences that can arise from the use of robots and digital technologies in various industries, which include experimental physics control systems. Risks include the compromising or malfunctioning of these systems, resulting in injury, equipment damage, loss of data or disruptions to critical infrastructure and services. Mitigating these risks involves taking proactive steps to reduce the likelihood of negative consequences and minimize their impact if they do occur. A comprehensive risk management approach that incorporates a combination of technical, organizational, and cultural strategies can help mitigate the potential risks through the implementation of the following strategies which will be discussed in this presentation: Regular maintenance and testing of robotic systems; Implementation of strong cyber security measures; Employee training and awareness programs; Adoption of industry standards and best practices; Developing contingency plans and backup systems; Establishing clear ethical and social guidelines.

OPC UA is a service-orientated communication architecture that supports platform-independent, data exchange between embedded micro-controllers, PLCs or PCs and cloudbased infrastructure. This makes OPC UA ideal for developing manufacturer independent communication to vendor specific PLCs, for example. With this in mind, we present an OPC UA to EPICS bridge that has been containerized with Docker to provide a micro-service for communicating between EPICS and OPC UA variables.

One of the main pillars of the ALBA Synchrotron Light Source (Barcelona, Spain) Strategy Plan is the preparation of ALBA to be upgraded to a fourth-generation light source. To accomplish this, a preliminary design of the accelerator has already been initiated in 2021. On the Computing side, the upgrade of the accelerator will require a comprehensive overhaul of most parts of the Control System, DAQ, Timing, and many other systems as well as DevOps strategies. This need for a major redesign will bring new architectural challenges, and opportunities to benefit from new technologies that were not present at the time ALBA was designed and build. This paper presents the preliminary design studies, pilot projects, new approaches to development coordination and management, and the preparation plan to acquire the knowledge and experience needed to excel in the ALBA II Control System Stack design.

The ALBA Synchrotron has started the work for up-grading the accelerator and beamlines towards a 4th gen-eration source, the future ALBA II, in 2030. A complete redesign of the magnets lattice and an upgrade of the beamlines will be required. But in addition, the success of the ALBA II project will depend on multiple factors. First, after thirteen years in operation, all the subsystems of the current accelerator must be revised. To guarantee their lifetime until 2060, all the possible ageing and obsoles-cence factors must be considered. Besides, many tech-nical enhancements have improved performance and reliability in recent years. Using the latest technologies will also avoid obsolescence in the medium term, both in the hardware and the software. Considering this, the pro-ject ALBA II Computing Preliminary Study (ALBA II CPS) was launched in mid-2021, identifying 11 work packages. In each one, a group of experts were selected to analyze the different challenges and needs in the compu-ting and electronics fields for future accelerator design: from power supplies technologies, IOC architectures, or PLC-based automation systems to synchronization needs, controls software stack, IT Systems infrastructure or ma-chine learning opportunities. Now, we have a clearer picture of what is required. Hence, we can build a realistic project plan to ensure the success of the ALBA II. It is time to get ALBA II off the ground.

The European Spallation Source (ESS) in Sweden is one of the largest science and technology infrastructure projects being built today. The facility design and construction include the most powerful linear proton accelerator ever built, a five-tonne, helium-cooled tungsten target wheel and 22 state-of-the-art neutron instruments. The Protection Systems Group (PSG) at ESS are responsible for the delivery and management of all the Personnel Safety Systems (PSS) and Machine Protection Systems (MPS), consisting of up to 30 PSS control systems and 6 machine protection systems. Due to the bespoke and evolving nature of the facility, managing the configuration of all these systems poses a significant challenge for the team. This paper will describe the methodology followed to ensure that the correct configuration is correctly implemented and maintained throughout the full engineering lifecycle for these systems.

Radio frequency (RF) conditioning is an essential stage during the preparation of particle accelerator cavities for operation. During this process the cavity field is gradually increased to the nominal parameters enabling the outgassing of the cavity and the elimination of surface defects through electrical arcing. However, this process can be time-consuming and labor-intensive, requiring skilled operators to carefully adjust the RF parameters. This proceeding presents the software tools for the development of an automatized EPICS control application with the aim to accelerate and introduce flexibility to the conditioning process. The results from the conditioning process of the ESS Radio-Frequency Quadrupole (RFQ) and the parallel conditioning of Drift-Tube Linac (DTL) tanks will be presented demonstrating the potential to save considerable time and resources in future RF conditioning campaigns.

ESS, Lund, Sweden

The European Spallation Source (ESS) is a research facility based in Lund, Sweden. Its linac will have an high peak current of 62.5 mA and long pulse length of 2.86 ms with a repetition rate of 14 Hz. The Fast Beam Interlock System (FBIS), as core system of the Beam Interlock System at ESS, is a critical system for ensuring the safe and reliable operation of the ESS machine. It is a modular and distributed system. FBIS will collect data from all relevant accelerator and target systems through ~300 direct inputs and decides whether beam operation can start or must stop. The FBIS operates at high data speed and requires low-latency decision-making capability to avoid introducing delays and to ensure the protection of the accelerator. This is achieved through two main hardware blocks equipped with FPGA based boards: a mTCA ’Decision Logic Node’ (DLN), executing the protection logic and realizing interfaces to Higher-Level Safety, Timing and EPICS Control Systems. The second block, a cPCI form-factor ’Signal Condition Unit’ (SCU), implements the interface between FBIS inputs/outputs and DLNs. In this paper we present the implementation of the FBIS control system, the integration of different hardware and software components and a summary on its performance during the latest beam commissioning phase to DTL4 Faraday Cup in 2023.

CoSAXS is the Coherent and Small Angle X-ray Scattering (SAXS) beamline placed at the diffraction-limited 3 GeV storage ring at MAX IV Laboratory. The beamline can deliver a very high photon flux ~10¹³ ph/s and it is equipped with state-of-the-art pixel detectors, suitable for experiments with a high time-resolution to be performed. In this work we present the upgraded beamline data acquisition strategy for a millisecond time-resolved SAXS/WAXS experiment, using laser light to induce temperature jumps or UV-excitation with the consequent structural changes on the system. In general terms, the beamline control system is based on TANGO and built on top of it, Sardana provides an advanced scan framework. In order to synchronize the laser light pulse on the sample, the X-ray fast shutter opening time and the X-ray detectors readout, hardware triggers are used. The implementation is done using PandABox, which generates the pulse train for the laser and for all active experimental channels, such as counters and detectors, in synchronization with the fast shutter opening time. PandABox integration is done with a Sardana Trigger Gate Controller, used to configure the pulses parameters as well to orchestrate the hardware triggers during a scan. This paper describes the experiment orchestration, laser light synchronization with multiple X-ray detector.

CERN, Meyrin, Switzerland

The controlled longitudinal emittance blow-up is necessary to ensure the stability of high-intensity LHC-type beams in the CERN SPS. It consists of diffusing the particles in the bunch core by injecting a bandwidth-limited noise into the beam phase loop of the main 200 MHz RF system. Obtaining the correct amplitude and bandwidth of this noise signal is non-trivial, and it may be tedious and time-demanding if done manually. An automatic approach was developed to speed up the determination of optimal settings. The problem complexity is reduced by splitting the blow-up into multiple sub-intervals for which the noise parameters are optimized by observing the longitudinal profiles at the end of each sub-interval. The derived bunch lengths are used to determine the objective function which measures the error with respect to the requirements. The sub-intervals are tackled sequentially. The optimization moves to the next one only when the previous sub-interval is completed. The proposed tool is integrated into the CERN generic optimization framework that features pre-implemented optimization algorithms. Both single- and multi-bunch high-intensity beams are quickly and efficiently stabilized by the optimizer, used so far in high-intensity studies. A possible extension to Bayesian optimization is being investigated.

The HL-LHC magnets play a critical role in the High-Luminosity Large Hadron Collider project, which aims to increase the luminosity of the LHC and enable more precise studies of fundamental physics. Ensuring the performance and reliability of these magnets requires high-precision measurements of their electrical properties during testing. To meet the R&D program needs of the new superconducting magnet technology, an accurate and generic voltage measurement system was developed after the testing and validation campaign of the LHC magnets. The system was based on a set of digital multimeter (DMM) cards installed in a PXI modular chassis and controlled using CERN’s in-house software development. It allowed for the measurement of the electrical properties of the magnet prototypes during their study phase. However, during the renovation of the magnet test benches and in preparation for the HL-LHC magnet series measurement, some limitations and instabilities were discovered during long recording measurements. As a result, it was decided to redesign the measurement system. The emergence and promises of the new PXIe platform, along with the requirement to build eight new systems to be operated similarly to the existing four, led to a complete redesign of the software. This article describes the various software techniques employed to address platform compatibility issues and significantly improve measurement accuracy, thus ensuring the reliability and quality of the data obtained from the HL-LHC magnet tests.

ISOLDE is part of the experimental infrastructure with-in the CERN accelerator complex that provides radioac-tive ion beams for studies of fundamental nuclear phys-ics, astrophysics, condensed matter physics and medical applications. Complementing the available controls in-frastructure, an easy-to-use set of applications was devel-oped to allow operators to record and display signals from multiple sources, as well as to provide drivers for non-standard, custom-made instruments and specialized off-the-shelf components. Aimed not only at software engineers but developers with any background, a generic and modular software template was developed in LabVIEW following a collab-oration between CERN and ANGARA Technology. This unified template can be extended to support interaction with any instrument and any newly developed applica-tion can be easily added to the existing control system and integrated into the CERN control and monitoring infrastructure. New modules and instrument drivers are easy to maintain as the structure and communication layers are all derived from the same template and based on the same components. In this paper, we will explain the implementation, ar-chitecture and structure of the template, as well as a wide variety of use cases - from motor control to image acquisi-tion and laser-specific equipment control. We will also show use cases of applications developed and deployed within a few days in the ISOLDE facility.

The Web-based Rapid Application Platform (WRAP) aims to provide a centralized, zero-code, drag-n-drop means of GUI creation*. It was developed at CERN to address the high maintenance cost of supporting multiple evolving GUI-technologies and minimising duplication of effort by those developing different GUI applications. WRAP leverages web technologies and existing controls infrastructure to provide a drop-in solution for a range of use cases. However, providing a centralized platform to cater for diverse needs and to interact with a multitude of data sources presented performance, design, and deployment challenges. This paper describes how the WRAP architecture has evolved to address these challenges, overcoming technological limitations, increasing usability and the resulting end-user adoption.

Web applications are becoming increasingly performant and are now capable, in many cases, of replacing traditional desktop applications. There is also a user demand for web-based applications, surely linked to their modern look & feel, their ease of access, and the overall familiarity of the users with web applications due to their pervasive nature. However, when it comes to a Controls environment, the limitations caused by the fact that web applications run inside a web browser are often seen as a major disadvantage when compared to native desktop applications. In addition, applications deployed in CERN’s Control Centre are tightly integrated with the control system and use a CERN-specific launcher and manager that does not easily integrate with web browsers. This paper presents an analysis of the approaches that have been considered for deploying web applications and integrating them with CERN’s control system. The implications on the development process, the IT infrastructure, the deployment methods as well as the performance impact on the resources of the target computers are also discussed.

The ATLAS (LHC detector) Liquid Argon Calorimeter is classified as a critical cryogenic system due to its requirement for uninterrupted operation. The system has been in continuous nominal operation since the start-up of the LHC, operating with very high reliability and availability. Over this period, control system maintenance was focused on the most critical hardware and software interventions, without direct impact on the process control system. Consequently, after several years of steady state operation, the process control system became obsolete (reached End of Life), requiring complex support and without the possibility of further improvements. This led to a detailed review towards a complete upgrade of the PLC hardware and process control software. To ensure uninterrupted operation, longer equipment lifecycle, and further system maintainability, the latest technology was chosen. This paper presents the methodology used for the process control system upgrade during development and testing phases, as well as the experience gained during deployment. It details the architecture of the new system based on a redundant (Hot Standby) PLC solution, the quality assurance protocol used during the hardware validation and software testing phases, and the deployment procedure.

CERN, Meyrin, Switzerland

The use of operational data from Enterprise Asset Management(EAM) systems has become an increasingly popular approach for conducting reliability analysis of industrial equipment. This paper presents a case study of how EAM data was used to analyse the reliability of CERN’s standard controls hardware, deployed and maintained by the Controls Electronics and Mechatronics group. The first part of the study involved the extraction, treatment and analysis of state-transition data to detect failures. The analysis was conducted using statistical methods, including failure-rate analysis and time-to-failure analysis to identify trends in equipment performance and plan for future obsolescence, upgrades and replacement strategies. The results of the analysis are available via a dynamic online dashboard. The second part of the study considers Front-End computers as repairable systems, composed of the previously studied non-repairable modules. The faults were recorded and analysed using the Accelerator Fault Tracking system. The study brought to light the need for high quality data, which led to improvements in the data recording process and refinement of the infrastructure team’s workflow. In the future, reliability analysis will become even more critical for ensuring the cost-effective and efficient operation of controls systems for accelerators. This study demonstrates the potential of EAM operational data to provide valuable insights into equipment reliability and inform decision-making for repairable and non-repairable systems.

Since upgrades of the CERN Large Hadron Collider are planned and design studies for a post-LHC particle accelerator are ongoing, it is key to ensure that the detectors and electronic components used in the CERN experiments and accelerators can withstand the high amount of radiation produced during particle collisions. To comply with this requirement, scientists perform radiation testing experiments, which consist in exposing these components to high levels of particle radiation to simulate the real operational conditions. The CERN Proton Irradiation Facility (IRRAD) is a well-established reference facility for conducting such experiments. Over the years, the IRRAD facility has developed a dedicated software infrastructure to support the control and monitoring systems used to manage these experiments, as well as to handle other important aspects such as dosimetry, spectrometry, and material traceability. In this paper, new developments and upgrades to the IRRAD software infrastructure are presented. These advances are crucial to ensure that the facility remains up-to-date and able to cope with the increasing (and always more complex) user needs. These software upgrades (some of them carried out within the EU-funded project AIDAinnova and EURO-LABS) will help to improve the efficiency and accuracy of the experiments performed at IRRAD and enhance the capabilities of this facility.

ESS, Lund, Sweden

The European Spallation Source (ESS), currently under construction and initial commissioning in Lund, Sweden, will be the brightest spallation neutron source in the world, when its driving proton linac achieves the design power of 5 MW at 2 GeV. Such a high power requires production, efficient acceleration, and almost no-loss transport of a high current beam, thus making the design and beam commissioning of this machine challenging. The recent commissioning runs (2021-2023) showed an enhanced need for a consistent and robust way of setting up the machine for beam production. One of the big challenges at ESS beam operations is aligning the machine setup and the timing setup limiting the need for operator actions. In this paper, we show a concept of using EPICS 7 NTTables to enable this machine settings consistency. Along with that, we also highlight a few challenges related to other EPICS tools like Save and Restore and Archiver.

CERN, Meyrin, Switzerland

The RF system of the CERN PS Booster (PSB) has been renovated to allow the extraction energy increase and the higher beam intensities required by the LHC Injectors Upgrade (LIU) project. It relies on accelerating cells installed in three straight sections of each of the four accelerating rings of PSB. Each cell is powered by one solid-state RF amplifier. This modularity is also embedded in its controls architecture, which is based on PLCs, several FESA (Front-End Software Architecture) classes, and specialized graphical user interfaces for both operation and expert use. The control system was commissioned during the Long Shutdown 2 (LS2) and allows for the nominal operation of the machine. This paper describes the design and implementation of the control system, as well as the system performance and achieved results.

Very early fire detection in equipment cabinets containing high power supply sources and power electronic switching devices is needed when building and tunnel fire detection systems may not be well placed to detect a fire until it is well established. Highly sensitive aspirating smoke detection systems which continuously sample the air quality inside equipment racks and give local power interlock in the event of smoke detection, are capable of cutting the source of power to these circuits at a very early stage, thereby preventing fires before they become fully established. Sampling pipework can also be routed to specific locations within the cabinet for more zone focused monitoring, while the electronic part of the detection system is located externally of the cabinet for easy operation and maintenance. Several of these early fire detection systems have recently been installed in LHC and SPS accelerator kicker installations, with many more planned. This paper compares the detection technology from typical manufacturers, presents the approach adopted and its mechanical installation and discusses the integration within different control architecture.

Fast pulsed kicker magnets are used across the various accelerators of CERN complex to inject and extract the beam. These kicker magnets, powered by high voltage pulsed generators and under vacuum, are prone to electrical breakdown during the pulse. To prepare the kicker magnet for reliable operation, or in case an electrical breakdown occurred, a conditioning is necessary: the magnet is pulsed gradually increasing the pulse voltage and length up to a value beyond operational conditions. This is a lengthy process that requires kicker experts on site to manually control the pulse voltage and length, and monitor the vacuum activity. For the start of LHC operation, a first automatic conditioning system was deployed on injection kicker magnet (MKI). Configurable voltage and pulse length ramps are automatically performed by the controller. In case abnormal vacuum activity occurs, the voltage is reduced and then the process continues. Based on this experience, a standardised algorithm has been developed, adding new features such as logarithmic ramp, or simulation of the whole conditioning cycle with test of reaction to vacuum activity. This new automatic conditioning system was deployed on several kicker systems across various CERN accelerators, allowing smoother conditioning, and great reduction on manpower. It also offers the possibility for further automate kicker system operation, starting automatically a magnet conditioning when needed without intervention of kickers experts, similarly as what was deployed for SPS Beam Dump System.

Spark Activity Monitoring for LHC Beam Dump System

CERN, Meyrin, Switzerland

LHC Beam Dump System is composed of 25 fast-pulsed magnets per beam to extract and dilute the beam onto an external absorber block. Each magnet is powered by a high voltage generator to discharge the energy stored in capacitors into the magnet by using high voltage switches. These switches are housed in air in cabinets which are not dust protected. In the past years of LHC operation, we noticed electrical sparks on the high voltage switch due to the release of accumulated charges on the surfaces of the insulators and the switches. These sparks can potentially cause self-trigger of the generators increasing the risk of asynchronous dumps which should be avoided as much as possible. In order to detect dangerous spark activity in the generators before a self-trigger occurs, a Spark Activity Monitoring (SAM) system was developed. SAM consists of 50 detection and acquisition systems deployed at the level of each high voltage generator, and one external global surveillance process. The detection and acquisition systems are based on digitisers to detect and capture spark waveforms coming from current pick-ups placed in various electrical paths inside each generator. The global surveillance process is collecting data from all the acquisition systems in order to assess the risk of self-trigger based on the detected sparks amplitude and rate. This paper describes the architecture, implementation, optimisation, deployment and operational experience of the SAM system.

As part of the LHC Injector Upgrade (LIU) project, the controls of the PSB and PS injection kickers at CERN have been upgraded during Long Shutdown 2 (LS2) from heterogeneous home-made electronic solutions to a modular and open architecture. Despite both kickers have significantly different functionalities, topologies and operational requirements, standardized hardware and software control blocks have been used for both systems. The new control architecture is built around a set of sub-systems, each one with a specific generic function required for the control of fast pulsed systems such as equipment and personnel safety, slow control and protection, high precision fast timing system, fast interlocking and protection, pulsed signal acquisition and analysis. Each sub-system comprises a combined integration of hardware components and associated low level software. This paper presents the functionality of the different sub-systems, illustrates how they have been integrated for the two different use-cases, discusses the lessons learned from these first implementations and identifies possible evolution in view of deployment in other installations during Long Shutdown 3 (LS3).

Industrial processes often use advanced control algorithms such as Model Predictive Control (MPC) and Machine Learning (ML) to improve performance and efficiency. However, deploying these algorithms can be challenging, particularly when they require significant computational resources and involve complex communication protocols between different control system components. To address these challenges, we showcase an approach leveraging industrial edge technologies to deploy such algorithms. An edge device is a compact and powerful computing device placed at the network’s edge, close to the process control. It executes the algorithms without extensive communication with other control system components, thus reducing latency and load on the central control system. We also employ an analytics function platform to manage the life cycle of the algorithms, including modifications and replacements, without disrupting the industrial process. Furthermore, we demonstrate a use case where an MPC algorithm is run on an edge device to control a Heating, Ventilation, and Air Conditioning (HVAC) system. An edge device running the algorithm can analyze data from temperature sensors, perform complex calculations, and adjust the operation of the HVAC system accordingly. In summary, our approach of utilizing edge technologies enables us to overcome the limitations of traditional approaches to deploying advanced control algorithms in industrial settings, providing more intelligent and efficient control of industrial processes.

CERN, Meyrin, Switzerland

In the CERN Super Proton Synchrotron (SPS), finding the source of an interlock signal has become increasingly unmanageable due to the complex interdependencies between the agents in both the beam interlock system (BIS) and the software interlock system (SIS). This often leads to delays, with the inefficiency in diagnosing beam stops impacting the overall performance of the accelerator. The Interlock Super Agent (ISA) was introduced to address this challenge. It traces the interlocks responsible for beam stops, regardless of whether they originated in BIS or SIS. By providing a better understanding of interdependencies, ISA significantly improves machine efficiency by reducing time for diagnosis and by documenting such events through platforms such as the Accelerator Fault Tracking system. The paper will discuss the practical implementation of ISA and its potential application throughout the CERN accelerator complex.

In the scope of the High Luminosity program of the Large Hadron Collider at CERN, the ATLAS and CMS experiments are advancing the preparation for the production, commissioning and installation of their new environment-friendly low-temperature detector cooling systems for their new trackers, calorimeters and timing layers. The selected secondary ¿on-detector¿ CO₂ pumped loop concept is the evolution of the successful 2PACL technique allowing for oil-free, stable, low-temperature control. The new systems are of unprecedented scale and largely more complex for both mechanics and controls than installations of today. This paper will present a general system overview and the technical progress achieved by the EP-DT group at CERN over the last few years in the development and construction of the future CO₂ cooling systems for silicon detectors at AT-LAS and CMS. We will describe in detail a homogenised infrastructure and control system architecture which spreads between surface and underground and has been applied to both experiments. Systems will be equipped with multi-level redundancy (electrical, mechanical and control) described in detail herein. We will discuss numerous controls-related challenges faced during the prototyping program and solutions deployed that spread from electrical design organization to instrumentation selection and PLC programming. We will finally present how we plan to organise commissioning and system performance check out.

PSI, Villigen PSI, Switzerland

After more than 20 years of successful operation the SLS facility will undergo a major upgrade, replacing the entire storage ring, which will result in a significantly improved beam emittance and brightness. In order to make use of improved beam characteristics, beamline upgrades will also play a crucial part in the SLS 2.0 project. However, offering our users an optimal beamtime experience will strongly depend on our ability to leverage the beamline control and data acquisition tools to a new level. Therefore, it is necessary to upgrade and modernize the majority of our current control system stack. This article provides an overview of the planned beamline control system upgrade from the technical as well as project management perspective. A portfolio of selected technical solutions for the main control system building blocks will be discussed. Currently, the controls HW in SLS is based on the VME platform, running the VxWorks operating system. Digital/analog I/O, a variety of motion solutions, scalers, high voltage power supplies, and timing and event system are all provided using this platform. A sensible migration strategy is being developed for each individual system, along with the overall strategy to deliver a modern high-level experiment orchestration environment. The article also focuses on the challenges of the phased upgrade, coupled with the unavoidable coexistence with existing VME-based legacy systems due to time, budget, and resource constraints.

SwissFEL X-ray Free Electron Laser at the Paul Scherrer Institute is a user facility designed to run in two electron bunch mode in order to serve simultaneously two experimental beamline stations. Two closely spaced (28 ns) electron bunches are accelerated in one RF macro pulse up to 3 GeV. A high stability resonant kicker system and a Lambertson septum magnet are used to separate the bunches and to send them to the respective beamlines[1]. The resonant kickers control system consists of various hardware and software components whose tasks are the synchronization of the kickers with the electron beam, pulse-to-pulse amplitude and phase measurement, generating pulsed RF power to excite a resonating deflection current, as well as movement of the mechanical tuning vanes of the resonant kickers. The feedback software monitors and controls all the important parameters. We present the integration solutions of these components into EPICS.

The ISIS Neutron and Muon Source accelerators have been controlled using Vsystem running on OpenVMS / Itaniums, while beamlines and instruments are controlled using EPICS. We outline the work in migrating accelerator controls to EPICS using the PVAccess protocol with a mixture of conventional EPICS IOCs and custom Python-based IOCs primarily deployed in containers on Linux servers. The challenges in maintaining operations with two control systems running in parallel are discussed, including work in migrating data archives and maintaining their continuity. Semi-automated conversion of the existing Vsystem HMIs to EPICS and the creation of new EPICS control screens required by the Target Station 1 upgrade are reported. The existing organisation of our controls network and the constraints this imposes on remote access via EPICS and the solution implemented are described. The successful deployment of an end-to-end EPICS system to control the post-upgrade Target Station 1 PLCs at ISIS is discussed as a highlight of the migration.

Tickit is an event-based multi-device simulation framework providing configuration and orchestration of complex simulations. It was developed at Diamond Light Source in order to overcome limitations presented to us by some of our existing hardware simulations. With the Tickit framework, simulations can be addressed with a compositional approach. It allows devices to be simulated individually while still maintaining the interconnected behaviour exhibited by their hardware counterparts. This is achieved by modelling the interactions between devices, such as electronic signals. Devices can be collated into larger simulated systems providing a layer of simulated hardware against which to test the full stack of Data Acquisition and Controls tools. We aim to use this framework to extend the scope and improve the interoperability of our simulations; enabling us to further improve the testing of current systems and providing a preferential platform to assist in development of the new Acquisition and Controls tools.

CHIMERA is an experimental nuclear fusion test facility which aims to simulate the intense magnetic fields and temperature gradients found within a tokamak fusion reactor. The control system at CHIMERA is based on EPICS and will have approximately 30 input/output controllers (IOCs) when it comes online in 2024. It will make heavy use of CSS Phoebus for its user interface, sequencer and alarm system. CHIMERA will use EPICS Archiver Appliance for data archiving and EPICS areaDetector to acquire high speed data which is stored in the HDF5 format. The control philosophy at CHIMERA emphasises PLC based control logic using mostly Siemens S7-1500 PLCs and using OPCUA to communicate with EPICS. EPICS AUTOSAVE is used both for manually setting lists of process variables (PVs) and for automatic restoration of PVs if an IOC must be restarted.

The PIP-II Machine Protection System (MPS) requires a dedicated set of tools for configuration control and management of the machine modes and beam modes of the accelerator. The protection system reacts to signals from various elements of the machine according to rules established in a setup database filtered by the program Mode Controller. This is achieved in accordance with commands from the operator and governed by the firmware logic of the MPS. This paper describes the firmware logic, architecture, and implementation of the program mode controller in an EPICs based environment.

RadiaSoft has been developing a flexible front-end framework, written in Python, for rapidly developing and testing automated sample alignment IOCs at Oak Ridge National Laboratory. We utilize YAML-formatted configuration files to construct a thin abstraction layer of custom classes which provide an internal representation of the external hardware within a controls system. The abstraction layer takes advantage of the PCASPy and PyEpics libraries in order to serve EPICS process variables & respond to read/write requests. Our framework allows users to build a new IOC that has access to information about the sample environment in addition to user-defined machine learning models. The IOC then monitors for user inputs, performs user-defined operations on the beamline, and reports on its status back to the control system. Our IOCs can be booted from the command line, and we have developed command line tools for rapidly running and testing alignment processes. These tools can also be accessed through an EPICS GUI or in separate Python scripts. This presentation provides an overview of our software structure and showcases its use at two beamlines at ORNL.

The industrial and medical accelerator industry is an ever-growing field with advancements in accelerator technology enabling its adoption for new applications. As the complexity of industrial accelerators grows so does the need for more sophisticated control systems to regulate their operation. Moreover, the environment for industrial and medical accelerators is often harsh and noisy as opposed to the more controlled environment of a laboratory-based machine. This environment makes control more challenging. Additionally, instrumentation for industrial accelerators is limited making it difficult at times to identify and diagnose problems when they occur. RadiaSoft has partnered with SLAC to develop new machine learning methods for control and anomaly detection for industrial accelerators. Our approach is to develop our methods using simulation models followed by testing on experimental systems. Here we present initial results using simulations of a room temperature s-band system.

Neutron scattering experiments are a critical tool for the exploration of molecular structure in compounds. The TOPAZ single crystal diffractometer at the Spallation Neutron Source studies these samples by illuminating samples with different energy neutron beams and recording the scattered neutrons. During the experiments the user will change temperature and sample position in order to illuminate different crystal faces and to study the sample in different environments. Maintaining alignment of the sample during this process is key to ensuring high quality data are collected. At present this process is performed manually by beamline scientists. RadiaSoft in collaboration with the beamline scientists and engineers at ORNL has developed a new machine learning based alignment software automating this process. We utilize a fully-connected convolutional neural network configured in a U-net architecture to identify the sample center of mass. We then move the sample using a custom python-based EPICS IOC interfaced with the motors. In this talk we provide an overview of our machine learning tools and show our initial results aligning samples at ORNL.

The Lawrence Livermore National Laboratory (LLNL) is delivering the Dual-mode Energetic Laser for Plasma and High Intensity Science (DELPHI) system to SLAC as part of the MEC-U project to create an unprecedented platform for high energy density experiments. The DELPHI control system is required to deliver short and/or long pulses at a 10 Hz firing rate with femto/pico-second accuracy sustained over fourteen 12-hour operator shifts to a common shared target chamber. The MEC-U system requires the integration of the control system with SLAC provided controls related to personnel safety, machine safety, precision timing, data analysis and visualization, amongst others. To meet these needs along with the system’s reliability, availability, and maintainability requirements, LLNL is delivering an EPICS based control system leveraging proven SLAC technology. This talk presents the conceptual design of the DELPHI control system and the methods planned to ensure its successful commissioning and delivery to SLAC.

LCLS-II is the first XFEL to be based on continuous-wave superconducting accelerator technology (CW-SCRF), with the X-ray pulses at repetition rates of up to 1 MHz. LCLS-II’s wire scanner motion control is based on Aerotech Ensemble controller. The position feedback and the beam loss monitor readings during a wire scan aim to measure the beam profile. To meet the measurement requirements under both low and high beam repetition rates, we redesign the software program for EPICS IOC, Aerotech controller, and develop a new User Interface (UI) based on PyDM. This paper will describe the software development details and the software commissioning result under LCLS-II’s production environment.

The SLAC ATCA Scope, a 4-channel dual scope, has an EPICS support package that runs on top of SLAC’s Common Platform software and firmware, and communicates with several high-performance systems in LCLS running on the 7-slot Advanced Telecommunications Computing Architecture (ATCA) crate. The software was completely refactored to improve the usability for IOC engineers. Once linked with an EPICS IOC, it initializes the scope hardware and instantiates the upper software stack providing a set of PVs to control the API and hardware, and to operate the oscilloscope. The exported PVs provide seamless means to configure triggers and obtain data acquisitions similar to a real oscilloscope. The ATCA scope probes are configured dynamically by the user to probe up to four inputs of the ATCA ADC daughter cards. The EPICS support package automatically manages available ATCA carrier board DRAM resources based on the number of samples requested by the user, allowing acquisitions of up to 8 GBytes per trigger. The user can also specify a desired sampling rate, and the ATCA Scope will estimate the nearest possible sampling rate using the current sampling frequency, and perform downsampling to try to match that rate. Adding the EPICS module to an IOC is simple and straightforward. The ATCA Scope support package works for all high-performance systems that have the scope common hardware implemented in its FPGAs. Generic interfaces developed in PyDM are also provided to the user to control the oscilloscope and enrich the user’s seamless overall experience.

The linear accelerator complex at the SLAC National Accelerator Laboratory has been upgraded to include LCLS-II, a new linac capable of producing beam power as high as several hundred kW with CW beam rates up to 1 MHz while maintaining existing capabilities from the copper machine. Because of these high-power beams, a new Machine Protection System with a latency of less than 100 us was designed and installed to prevent damage to the machine when a fault or beam loss is detected. The new LCLS-II MPS must work in parallel with the existing MPS from the respective sources all the way through the user hutches to provide a mechanism to reduce the beam rate or shut down operation in a beamline without impacting the neighboring beamline when a fault condition is detected. Because either beamline can use either accelerator as its source and each accelerator has different operating requirements, great care was taken in the overall system design to ensure the necessary operation can be achieved with a seamless experience for the accelerator operators. The overall system design of the LCLS-II MPS software including the ability to interact with the existing systems and the tools developed for the control room to provide the user operation experience will be described.

The LCLS-II Preemptive Machine Protection System (PMPS) safeguards diagnostics, optics, beam-shaping components and experiment apparatus from damage by excess XFEL average power and single-shots. The dynamic nature of these systems requires a somewhat novel approach to a machine protection system design, relying more heavily on preemptive interlocks and automation to avoid mismatches between device states and beam parameters. This is in contrast to reactive machine protection systems. Safe beam parameter sets are determined from the combination of all integrated devices using a hierarchical arrangement and all state changes are held until beam conditions are assured to be safe. This machine protection system design utilizes the Beckhoff industrial controls platform and EtherCAT, and is woven into the LCLS subsystem controllers as a code library and standardized hardware interface.

A new open-source PyQT-based archive viewer application has been developed at SLAC National Accelerator Laboratory. The viewer’s main purpose is to visualize both live values and historical Process Variable (PV) data retrieved from the EPICS Archive Appliances. It is designed as both a stand-alone application and to be easily launched from widgets on PyDM operator interfaces. In addition to providing standard configurability for things like traces, formulas, style and data exporting, it provides post-processing capabilities for filtering and curve fitting. The current release supports standard enumerated and analog data types as well as waveforms. Extension of this to support EPICS7 normative data types such as NTTable and NTNDArray is under development.

SLAC recently commissioned a new continuous-wave, MHz repetition-rate Superconducting (SC) Linear Accelerator (Linac). This accelerator can produce a 4 GeV electron beam that drives two dedicated Hard and Soft X-ray Undulator lines as part of the Linac Coherent Light Source (LCLS) Free Electron Laser. A new Python-based longitudinal feedback is used to control the electron beam energy and bunch length along the accelerator. This feedback was written to be simple, easily maintainable and easily portable for use on other accelerators or systems as a general-purpose feedback with minimal dependencies. Design and operational results of the feedback will be discussed, along with the Graphical User Interfaces built using Python Display Manager (PyDM).

The temperature control of crystal optics is critical for ultrahigh resolution applications such as those used in meV-resolved Inelastic Scattering. Due to the low count rate and long acquisition time of these experiments, for 1-meV energy resolution, the absolute temperature stability of the crystal optics must be maintained below 4 mK to ensure the required stability of lattice constant, thereby ensuring the energy stability of the optics. Furthermore, the temperature control with sub-mK precision enables setting the absolute temperature of individual crystal, making it possible to align the reflection energy of each crystal’s rocking curve in sub-meV resolution thereby maximizing the combined efficiency of the crystal optics. In this contribution, we report the details of an EPICS control system using PT1000 sensors, Keithley 3706A 7.5 digits sensor scanner, and Wiener MPOD LV power supply for the analyzer crystals of the Inelastic X-ray Scattering (IXS) beamline 10-ID at NSLS-II**. We were able to achieve absolute temperature stability below 1 mK and sub-meV energy alignment for several asymmetrically cut analyzer crystals. The EPICS ePID record was used for the control of the power supplies based on the PT1000 sensor input that was read with 7.5 digits accuracy from the Keithley 3706A scanner. The system enhances the performance of the meV-resolved IXS spectrometer with currently a 1.4 meV total energy resolution and unprecedented spectral sharpness for studies of atomic dynamics in a broad range of materials.

The Second Target Station (STS) Project will expand the capabilities of the existing Spallation Neutron Source (SNS), with a suite of neutron instruments optimized for long wavelengths. A new accelerator transport line will be built to deliver one out of four SNS pulses to the new target station. The Integrated Control Systems (ICS) will provide remote control, monitoring, OPI, alarms, and archivers for the accelerator systems, such as magnets power supply, vacuum devices, and beam instrumentation. The ICS will upgrade the existing Linac LLRF controls to allow independent operation of the FTS and STS and support different power levels of the FTS and STS proton beam. The ICS accelerator controls are in the phase of preliminary design for the control systems of magnet power supply, vacuum, LLRF, Timing, Machine protection system (MPS), and computing and machine network. The accelerator control systems build upon the existing SNS Machine Control systems, use the SNS standard hardware and EPICS software, and take full advantage of the performance gains delivered by the PPU Project at SNS.

The Relativistic Heavy Ion Collider (RHIC) Cryogenic Refrigerator System is the cryogenic heart that allows RHIC superconducting magnets to operate. Parts of the refrigerator are two stages of compression composed of ten first and five second-stage compressors. Compressors are critical for operations. When a compressor faults, it can impact RHIC beam operations if a spare compressor is not brought online as soon as possible. The potential of applying machine learning to detect compressor problems before a fault occurs would greatly enhance Cryo operations, allowing an operator to switch to a spare compressor before a running compressor fails, minimizing impacts on RHIC operations. In this work, various data analysis results on historical compressor data are presented. It demonstrates an autoencoder-based method, which can catch early signs of compressor trips so that advance notices can be sent for the operators to take action.

The Pointing Stabilization Algorithm for the Coherent Electron Cooling Laser Transport at RHIC

Coherent electron cooling (CeC) is a novel cooling technique being studied in the Relativistic Heavy Ion Collider (RHIC) as a candidate for strong hadron cooling in the Electron-Ion Collider (EIC). The electron beam used for cooling is generated by laser light illuminating a photocathode after that light has traveled approximately 40 m from the laser output. This propagation is facilitated by three independent optical tables that move relative to one another in response to changes in time of day, weather, and season. The alignment drifts induced by these environmental changes, if left uncorrected, eventually render the electron beam useless for cooling. They are therefore mitigated by an active "slow" pointing stabilization system found along the length of the transport, copied from the system that transversely stabilized the Low Energy RHIC electron Cooling (LEReC) laser beam during the 2020 and 2021 RHIC runs. However, the system-specific optical configuration and laser operating conditions of the CeC experiment required an adapted algorithm to address inadequate beam position data and achieve greater dynamic range. The resulting algorithm was successfully demonstrated during the 2022 run of the CeC experiment and will continue to stabilize the laser transport for the upcoming run. A summary of the algorithm is provided.

The traditional approach of step scanning in X-ray experiments is often inefficient and may increase the risk of sample radiation damage. In order to overcome these challenges, a new position-based continuous energy scanning system has been developed at MAX IV Laboratory. This system enables stable and repeatable measurements by continuously moving the motors during the scan. Triggers are generated in hardware based on the motor encoder positions to ensure precise data acquisition. Prior to the scan, a list of positions is generated, and triggers are produced as each position is reached. The system uses Tango and Sardana for control and a TriggerGate controller to calculate motor positions and configure the PandABox, which generates the triggers. The system is capable of scanning a single motor, such as a sample positioner, or a combined motion like a monochromator and undulator. In addition, the system can use the parametric trajectory mode of IcePAP driver, which enables continuous scans of coupled axes with non-linear paths. This paper presents the current status of the position-based continuous energy scanning system for BioMAX, FlexPES, and FinEst beamlines at MAX IV and discusses its potential to enhance the efficiency and accuracy of data acquisition at beamline endstations.

Within the myriad of day to day activities, a consistent and standardised code base can be hard to achieve, especially when a diverse array of developers across different fields are involved. By creating tools and wizards, it becomes possible to guide the developer and/or user through many of the development and generic tasks associated with a Programmable Logic Controller (PLC). At the European X-Ray Free Electron Laser Facility (EuXFEL), we have striven to achieve structure and consistency within the PLC framework through the use of C# tools which are embedded into the TwinCAT environment (Visual Studio) as extensions. These tools aid PLC development and deployment, and provide a clean and consistent way to develop, configure and integrate code from the hardware level, to the Supervisory Control And Data Acquisition (SCADA) system.

State Machine Operation of Complex Systems

operation, vacuum, linac, cryomodule

929

P.M. Hanlet
Fermilab, Batavia, Illinois, USA

Operation of complex systems which depend on one or more other systems with many process variables often operate in more than one state. For each state there may be a variety of parameters of interest, and for each of these, one may require different alarm limits, different archiving needs, and have different critical parameters. Relying on operators to reliably change 10s-1000s of parameters for each system for each state is unreasonable. Not changing these parameters results in alarms being ignored or disabled, critical changes missed, and/or possible data archiving problems. To reliably manage the operation of complex systems, such as cryomodules (CMs), Fermilab is implementing state machines for each CM and an over-arching state machine for the PIP-II superconducting linac (SCL). The state machine transitions and operating parameters are stored/restored to/from a configuration database. Proper implementation of the state machines will not only ensure safe and reliable operation of the CMs, but will help ensure reliable data quality. A description of PIP-II SCL, details of the state machines, and lessons learned from limited use of the state machines in recent CM testing will be discussed.

To establish the engineering and science background of radio astronomy in SKA African partner countries, a need was identified to develop a training telescope which would serve as a vehicle for demonstrating the principles. The Scale Training Telescope (STT) will be used as an interactive teaching tool for the basics of antenna structure and antenna control, both in the design, assembly and operation of the radio antenna. The antenna aims to work as closely to a real radio telescope antenna as possible. The STT allows students at various academic levels in different educational institutions the ability to access an antenna design that can be assembled and operated by the students. The paper will describe the mechanical, electrical and software elements of the STT. The mechanical elements range from the structural base to the rotating dish of the radio telescope antenna. The electrical elements incorporate the electromechanical components used to move the antenna as well as the wiring and powering of the antenna. The software is used to control the antenna system as well as collect, process and visualise the resulting data. A software-based user interface will allow the students to control and monitor the antenna system. The PLC-based (Programmable Logic Controller) control system facilitates the motion control of the antenna, in both the azimuth and elevation axes.

The Phoebus toolkit consists of a variety of control system applications providing user interfaces to control systems and middle-layer services. Phoebus is the latest incarnation of Control System Studio (CS-Studio), which has been redesigned replacing the underlying Eclipse RCP framework with standard Java alternatives like SPI, preferences, etc. Additionally the GUI toolkit was switched from SWT to JavaFX. This new architecture has not only simplified the development process while preserving the extensible and pluggable aspects of RCP, but also improved the performance and reliability of the entire toolkit. The Phoebus technology stack includes a set of middle-layer services that provide functionality like archiving, creating and restoring system snapshots, consolidating and organizing alarms, user logging, name lookup, etc. Designed around modern and widely used web and storage technologies like Spring Boot, Elastic, MongoDB, Kafka, the Phoebus middle-layer services are thin, scalable, and can be easily incorporated in CI/CD pipelines. The clients in Phoebus leverage the toolkit’s integration features, including common interfaces and utility services like adapter and selection, to provide users with a seamless experience when interacting with multiple services and control systems. This presentation aims to provide an overview of the Phoebus technology stack, highlighting the benefits of integrated tools in Phoebus and the microservices architecture of Phoebus middle-layer services.

VME architecture was developed in late 1970s. It has proved to be a rugged control system hardware platform for the last four decades. Today the VME hardware platform is facing four challenges from 1) backplane communication speed bottleneck; 2) computing power limits from centralized computing infrastructure; 3) obsolescence and cost issues to support a real-time operating system; 4) obsolescence issues of the legacy VME hardware. The next generation hardware platform such as ATCA and microTCA requires fundamental changes in hardware and software. It also needs large investment. For many legacy system upgrades, this approach is not applicable. We will discuss an open-source hardware platform, VME2E (VME to Ethernet), which allows the one-to-one replacement of legacy VME module without disassembling of the existing VME system. The VME2E has the VME form factor. It can be installed the existing VME chassis, but without use the VME backplane to communicate with the front-end computer and therefore solves the first three challenges listed above. The VME2E will only take advantage of two good benefits from a VME system: stable power supply which VME2E module will get from the backplane, and the cooling environment. The VME2E will have the most advanced 14nm Xilinx FPGA SOM with GigE for parallel computing and high speed communication. It has a high pin count (HPC) FPGA mezzanine connector (FMC) to benefit the IO daughter boards supply of the FMC ecosystem. The VME2E is designed as a low cost, open-source common platform for legacy VME upgrade.

The Hefei Advanced Light Facility (HALF) is a 2.2-GeV 4th synchrotron radiation light source, which is scheduled to start construction in Hefei, China in 2023. The HALF contains an injector and a 480-m diffraction limited storage ring, and 10 beamlines for phase one. The HALF control system is EPICS based with integrated application and data platforms for the entire facility including accelerator and beamlines. The unified infrastructure and network architecture are designed to build the control system. The infrastructure provides resources for the EPICS development and operation through virtualization technology, and provides resources for the storage and process of experimental data through distributed storage and computing clusters. The network is divided into the control network and the dedicated high-speed data network by physical separation, the control network is subdivided into multiple subnets by VLAN technology. Through estimating the scale of the control system, the 10Gbps control backbone network and the data network that can be expanded to 100Gbps can fully meet the communication requirements of the control system. This paper reports the control system architecture design and the development work of some key technologies in details.

Funding: This work is supported by Department of Energy contract DE-AC02-76SF00515.
The LCLS-II Experiment System Vacuum Controls Architecture is a collection of vacuum system design templates, interlock logics, supported components (eg. gauges, pumps, valves), interface I/O, and associated software libraries which implement a baseline functionality and simulation. The architecture also includes a complement of engineering and deployment tools including cable test boxes or hardware simulators, as well as some automatic configuration tools. Vacuum controls at LCLS spans from rough vacuum in complex pumping manifolds, protection of highly-sensitive x-ray optics using fast shutters, maintenance of ultra-high vacuum in experimental sample delivery setups, and beyond. Often, the vacuum standards for LCLS systems exceeds what most vendors are experienced with. The system must maintain high-availability, while also remaining flexible and handling ongoing modifications. This paper will review the comprehensive architecture, the requirements of the LCLS systems, and introduce how to use it for new vacuum system designs. The architecture is meant to influence all phases of a vacuum system lifecycle, and ideally could become a shared project for installations beyond LCLS-II.

The LCLS-II Precision Timing Control System

SLAC, Menlo Park, California, USA

The LCLS-II precision timing system is responsible for the synchronization of optical lasers with the LCLS-II XFEL. The system uses both RF and optical references for synchronization. In contrast to previous systems used at LCLS the optical lasers are shared resources, and must be managed during operations. The timing system consists of three primary functionalities: RF reference distribution, optical reference distribution, and a phase-locked loop (PLL). This PLL may use either the RF or the optical reference as a feedback source. The RF allows for phase comparisons over a relatively wide range, albeit with limited resolution, while the optical reference enables very fine phase comparison (down to attoseconds), but with limited operational range. These systems must be managed using high levels of automation. Much of this automation is done via high-level applications developed in EPICS. The beamline users are presented with relatively simple interfaces that streamline operation and abstract much of the system complexity away. The system provides both PyDM GUIs as well as python interfaces to enable time delay scanning in the LCLS-II DAQ.

The National Ignition Facility (NIF) is the world’s largest and most energetic 192-laser-beam system which conducts experiments in High Energy Density (HED) physics and Inertial Confinement Fusion (ICF). In December 2022, the NIF achieved a scientific breakthrough when, for the first time ever, the ICF ignition occurred under laboratory conditions. The key to the NIF’s experimental prowess and versatility is not only its power but also its precise control. The NIF controls and data systems place the experimenter in full command of the laser and target diagnostics capabilities. The recently upgraded Master Oscillator Room (MOR) system precisely shapes NIF laser pulses in the temporal, spatial, and spectral domains. Apart from the primary 10-meter spherical target chamber, the NIF laser beams can now be directed towards two more experimental stations to study laser interactions with optics and large full beam targets. The NIF’s wide range of target diagnostics continues to expand with new tools to probe and capture complex plasma phenomena using x-rays, gamma-rays, neutrons, and accelerated protons. While the increasing neutron yields mark the NIF’s steady progress towards exciting experimental regimes, they also require new mitigations for radiation damage in control and diagnostic electronics. With many NIF components approaching 20 years of age, a Sustainment Plan is now underway to modernize NIF, including controls and information systems, to assure NIF operations through 2040.

Recent upgrades to the Instrumentation and Control System at Los Alamos Neutron Science Center (LANSCE) have significantly improved its maintainability and performance. These changes were the first strategic steps towards a larger vision to standardize the hardware form factors and software methodologies. Upgrade efforts are being prioritized though a risk-based approach and funded at various levels. With a major recapitalization project finished in 2022 and modernization project scheduled to start possibly in 2025, current efforts focus on the continuation of upgrade efforts that started in the former and will be finished in the later time frame. Planning and executing these upgrades are challenging considering that some of the changes are architectural in nature, however, the functionality needs to be preserved while taking advantage of technology progressions. This is compounded by the fact that those upgrades can only be implemented during the annual 4-month outage. This paper will provide an overview of our vision, strategy, challenges, recent accomplishments, as well as future planned activities to transform our 50-year-old control system into a modern state-of-the-art design.

The migration of the controls system for the ISIS accelerator from Vsystem to EPICS presents a significant challenge and risk to day-to-day operations. To minimise this impact throughout the transition, a software bridge between the two control systems has been developed that allows the phased porting of HMIs and hardware. The hybrid Vsystem and EPICS system also allows the continued use of existing feedback control applications that now require interaction between both control systems, for example the halo steering operation in Target Station 1. This work describes the implementation of this bridge, referred to as PVEcho, for the mapping of Vsystem channels to EPICS PVs and vice versa. The position within the wider ISIS controls software stack is outlined as well as how it utilises Python libraries for EPICS. Finally, we will discuss the software development practices applied that have allowed the bridge to run reliably for months at a time.

The Spallation Neutron Source at Oak Ridge National Laboratory has been in operation since 2006. In order to achieve high operating reliability and availability as mandated by the sponsor, all systems participating in the production of neutrons need to be maintained to the highest achievable standard. This includes SNS integrated control system, comprising of specialized hardware and software, as well as computing and networking infrastructure. While machine upgrades are extending the control system with new and modern components, the established part of control system requires continuous modernization efforts due to hardware obsolescence, limited lifetime of electronic components, and software updates that can break backwards compatibility. This article discusses challenges of sustaining control system operations through decades of facility lifecycle, and presents a methodology used at SNS for continuous control system improvements that was developed by analyzing operational data and experience.

Fermilab has traditionally not been an EPICS house, as such expertise in EPICS is limited and scattered. However, PIP-II will be using EPICS for its control system. Furthermore, when PIP-II is operating, it must to interface with the existing, though modernized (see ACORN) legacy control system. We have developed and deployed a software pipeline that addresses these needs and presents to developers a tested and robust software framework, including template IOCs from which new developers can quickly gain experience. In this presentation, we will discuss the motivation for this work, the implementation of a continuous integration/continuous deployment pipeline, testing, template IOCs, and the deployment of user applications. We will also discuss how this is used with the current PIP-II teststand and lessons learned.

The ALICE experiment studies ultra relativistic heavy ion collisions at the Large Hadron Collider at CERN. Its Detector Control System (DCS) has been ensuring the experiment safety and stability of data collection since 2008. A small central team at CERN coordinated the developments with collaborating institutes and defined the operational principles and tools. Although the basic architecture of the system remains valid, it has had to adapt to the changes and evolution of its components. The introduction of new detectors into ALICE has required the redesign of several parts of the system, especially the front-end electronics control, which triggered new developments. Now, the DCS enters the domain of data acquisition, and the controls data is interleaved with the physics data stream, sharing the same optical links. The processing of conditions data has moved from batch collection at the end of data-taking to constant streaming. The growing complexity of the system has led to a big focus on the operator environment, with efforts to minimize the risk of human errors. This presentation describes the evolution of the ALICE control system over the past 15 years and highlights the significant improvements made to its architecture. We discuss how the challenges of integrating components developed in tens of institutes worldwide have been mastered in ALICE.
This proposed contribution is complemented by poster submitted by Ombretta Pinazza who will explain the user interfaces deployed in ALICE.

As modern control systems grow in complexity, ensuring observability and traceability becomes more challenging. To meet this challenge, we present a novel solution that seamlessly integrates with multiple SCADA frameworks to provide end-to-end visibility into complex system interactions. Our solution utilizes Elastic APM to monitor and trace the performance of system components, allowing for real-time analysis and diagnosis of issues. In addition, our solution is built using reactive design principles and asynchronous communication, enabling it to scale to meet the demands of large, distributed systems. This presentation will describe our approach and discuss how it can be applied to various use cases, including particle accelerators and other scientific facilities. We will also discuss the benefits of our solution, such as improved system observability and traceability, reduced downtime, and better resource allocation. We believe that our approach represents a significant step forward in the development of modern control systems, and we look forward to sharing our work with the community at ICALEPCS 2023.

CERN, Meyrin, Switzerland

The CMS experiment relies on its Detector Control System (DCS) to monitor and control over 10 million channels, ensuring a safe and operable detector that is ready to take physics data. The data is archived in the CMS Oracle conditions database, which is accessed by operators, trigger and data acquisition systems. In the upcoming extended year-end technical stop of 2023/2024, the CMS DCS software will be upgraded to the latest WinCC-OA release, which will utilise the SQLite database and the Next Generation Archiver (NGA), replacing the current Raima database and RDB manager. Taking advantage of this opportunity, CMS has developed its own version of the NGA backend to improve its DCS database interface. This paper presents the CMS DCS NGA backend design and mechanism to improve the efficiency of the read-and-write data flow. This is achieved by simplifying the current Oracle conditions schema and introducing a new caching mechanism. The proposed backend will enable faster data access and retrieval, ultimately improving the overall performance of the CMS DCS.

Assonant: A Beamline-Agnostic Event Processing Engine for Data Collection and Standardization

experiment, software, synchrotron, data-management

1025

LNLS, Campinas, Brazil

Synchrotron radiation facilities comprise beamlines designed to perform a wide range of X-ray experimental techniques which require complex instruments to monitor thermodynamic variables, sample-related variables, among others. Thus, synchrotron beamlines can produce heterogeneous sets of data and metadata, hereafter referred to as data, which impose several challenges to standardizing them. For open science and FAIR principles, such standardization is paramount for research reproducibility, besides accelerating the development of scalable and reusable data-driven solutions. To address this issue, the Assonant was devised to collect and standardize the data produced at beamlines of Sirius, the Brazilian fourth-generation synchrotron light source. This solution enables a NeXus-compliant technique-centric data standard at Sirius transparently for beamline teams by removing the burden of standardization tasks from them and providing a unified standardization solution for several techniques at Sirius. The Assonant implements a software interface to abstract data format-related specificities and to send the produced data to an event-driven infrastructure composed of streaming processing and microservices, able to transform the data flow according to NeXus*. This paper presents the development process of Assonant, the strategy adopted to standardize beamlines with different operating stages, and challenges faced during the standardization process for macromolecular crystallography and imaging data at Sirius.

With the advancements in beamline instrumentation, synchrotron research facilities have seen a significant improvement. The detectors used today can generate thousands of frames within seconds. Consequently, an organized and adaptable framework is essential to facilitate the efficient access and assessment of the enormous volumes of data produced. Our communication presents a metadata management solution recently implemented at MAX IV, which automatically retrieves and records metadata from Tango devices relevant to the current experiment. The solution includes user-selected scientific metadata and predefined defaults related to the beamline setup, which are integrated into the Sardana control system and automatically recorded during each scan via the SciFish[1] library. The metadata recorded is stored in the SciCat[2] database, which can be accessed through a web-based interface called Scanlog[3]. The interface, built on ReactJS, allows users to easily sort, filter, and extract important information from the recorded metadata. The tool also provides real-time access to metadata, enabling users to monitor experiments and export data for post-processing. These new software tools ensure that recorded data is findable, accessible, interoperable and reusable (FAIR[4]) for many years to come. Collaborations are on-going to develop these tools at other particle accelerator research facilities.

Awareness of the need for FAIR data management has increased in recent years but examples of how to achieve this are often missing. Focusing on the large-scale instrument A4 at the MAMI accelerator, we transfer findings of the EMIL project at the BESSY synchrotron* to improve raw data, i.e. the primary output stored on long-term basis, according to the FAIR principles. Here, the instrument control software plays a key role as the central authority to start measurements and orchestrate connected (meta)data-taking processes. In regular discussions we incorporate the experiences of a wider community and engage to optimize instrument output through various measures from conversion to machine-readable formats over metadata enrichment to additional files creating scientific context. The improvements were already applied to currently built next generation instruments and could serve as a general guideline for publishing data sets.

We introduce a radiation-tolerant multi-application wireless IoT platform, specifically designed for deployment in harsh environments such as particle accelerators. The platform integrates radiation-tolerant hardware with the possibility of covering different applications and use cases, including temperature and humidity monitoring, as well as simple equipment control functions. The hardware is capable of withstanding high levels of radiation and communicates wirelessly using LoRa technology, which reduces infrastructure costs and enables quick and easy deployment of operational devices. To validate the platform’s suitability for different applications, we have deployed a radiation monitoring version in the CERN particle accelerator complex and begun testing multi-purpose application devices in radiation test facilities. Our radiation-tolerant IoT platform, in conjunction with the entire network and data management system, opens up possibilities for different applications in harsh environments.

The SBIR funded Helium Mass Flow Monitor System, developed by Jefferson Lab and Hyperboloid LLC, is designed to measure the health of cavities in a Cryomodule in real-time. It addresses the problem of cavities with low Q₀, which generate excess heat and evaporation from the 2 K super-fluid helium bath used to cool the cavities. The system utilizes a unique meter that is based on a superconducting component. This device enables high-resolution measurements of the power dissipated in the cryomodule while the accelerator is operating. It can also measure individual Cavity Q₀s when the beam is turned off. The Linux-based control system is an integral part of this device, providing the necessary control and data processing capabilities. The initial implementation of the Helium Mass Flow Monitor System at Jefferson Lab was done using LabView, a couple of current sources & a nano-voltmeter. Once the device was proven to work at 2K the controls transitioned to a hand wired PCB & Raspberry Pi interfaced to the open-source Experimental Physics and Industrial Control System (EPICS) control system. The EE support group preferred to support a LabJack T7 over the rPi. 12 chassis were built and the system is being deployed as the cryogenic U-Tubes become available.

Monitoring the harsh environment within an operating accelerator is a notoriously challenging problem. High radiation, lack of space, poor network connectivity, or extreme temperatures are just some of the challenges that often make ad-hoc, fixed sensor networks the only viable option. In an attempt to increase the flexibility of deploying different types of sensors on an as-needed basis, we have built upon the existing body of work in the field and developed a robotic platform to be used as a mobile sensor platform. The robot is constructed with the objective of minimizing costs and development time, strongly leveraging the use of Commercial-Off-The-Shelf (COTS) hardware and open-source software (ROS). Although designed to be remotely operated by a user, the robot control system incorporates sensors and algorithms for autonomous obstacle detection and avoidance. We have deployed the robot to a number of missions within the SLAC LCLS accelerator complex with the double objective of collecting data to assist accelerator operations and of gaining experience on how to improve the robustness and reliability of the platform. In this work we describe our deployment scenarios, challenges encountered, solutions implemented and future improvement plans.

Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy.
Magnetic sensors have been developed utilizing various physical phenomena such as Electromagnetic Induction, Hall Effect, Tunnel Magnetoresistance(TMR), Giant Magnetoresistance (GMR), Anisotropic Magnetoresistance (AMR) and Giant Magnetoimpedance (GMI). The compatibility of solid-state magnetic sensors with complementary metal-oxide-semiconductor (CMOS) fabrication processes makes it feasible to achieve integration of sensor with sensing and computing circuitry at the same time, resulting in systems on chip. In this paper we describe application of AMR, TMR and Hall effect integrated sensors for precise measurement of 3D static magnetic field in wide range of magnitudes from 10^-6 T to 0.3 T, as well as pulsed magnetic field up to 0.3 T.

China’s Ministry of Science and Technology supports Peking University in constructing a proton radiotherapy device based on a petawatt (PW) laser accelerator. The control system’s functionality and performance are vital for the accelerator’s reliability, stability, and efficiency. The PW laser accelerator control system has a three-layer distributed architecture, including device control, front-end (input/output) control and central control (data management, and human-machine interface) layers. The software platform primarily uses EPICS, supplemented by PLC, Python, and Java, while the hardware platform comprises industrial control computers, servers, and private cloud configurations. The control system incorporates various subsystems that manage the laser, target field, beamline, safety interlocks, conditions, synchronization, and functionalities related to data storage, display, and more. This paper presents a control system implementation suitable for laser accelerators, providing valuable insights for future laser accelerator control system development.

Since 2021 the Tango Controls collaboration has improved and optimised its efforts in many areas. Not only have Special Interest Group meetings (SIGs) been introduced to speed up the adoption of new technologies or improvements, the kernel has switched to a fixed six-month release cycle for quicker adoption of stable kernel versions by the community. CI/CD provides now early feedback on test failures and compatibility issues. Major code refactoring allowed for a much more efficient use of developer resources. Relevant bug fixes, improvements and new features are now adopted at a much higher rate than ever before. The community participation has also noticeably improved. The kernel switched to C++14 and the logging system is undergoing a major refactoring. Among many new features and tools is jupyTango, Jupyter Notebooks on Tango Controls steroids. PyTango is now easy to install via binary wheels, old Python versions are no longer supported, the build-system is switching to CMake, and releases are now made much closer to stable cppTango releases.

Equipment controlled by the Square Kilometre Array (SKA) Control System will have a TANGO interface for control and monitoring. Commands on TANGO device servers have a 3000 milliseconds window to complete their execution and return to the client. This timeout places a limitation on some commands used on SKA TANGO devices which take longer than the 3000 milliseconds window to complete; the threshold is more stricter in the SKA Control System (CS) Guidelines. Such a command, identified as a Long Running Command (LRC), needs to be executed asynchronously to circumvent the timeout. TANGO has support for an asynchronous device which allows commands to be executed slower than 3000 milliseconds by using a coroutine to put the task on an event loop. During the exploration of this, a decision was made to implement a custom approach in our base repository which all devices depend on. In this approach, every command annotated as ¿long running¿ is handed over to a thread to complete the task and its progress is tracked through attributes. These attributes report the queued commands along with their progress, status and results. The client is provided with a unique identifier which can be used to track the execution of the LRC and take further action based on the outcome of that command. LRCs can be aborted safely using a custom TANGO command. We present the reference design and implementation of the Long Running Commands for the SKA Controls System.

The Athena Platform aims to replace, upgrade and modernise the capabilities of Diamond Light Source’s acquisition and controls tools, providing an environment for better integration with information management and analysis functionality. It is a service-based experiment orchestration system built on top of NSLS-II’s Python based Bluesky/Ophyd data collection framework, providing a managed and extensible software deployment local to the beamline. By using industry standard infrastructure provision, security and interface technologies we hope to provide a sufficiently flexible and adaptable platform, to meet the wide spectrum of science use cases and beamline operation models in a reliable and maintainable way. In addition to a system design overview, we describe here some initial test deployments of core capabilities to a number of Diamond beamlines, as well as some of the technologies developed to support the overall delivery of the platform.

The Karabo distributed control system has been developed to address the challenging requirements of the European X-ray Free Electron Laser facility*, which include custom-made hardware, and high data rates and volumes. Karabo implements a broker-based SCADA environment**. Extensions to the core framework, called devices, provide control of hardware, monitoring, data acquisition and online processing on distributed hardware. Services for data logging and for configuration management exist. The framework exposes Python and C++ APIs, which enable developers to quickly respond to requirements within an efficient development environment. An AI driven device code generator facilitates prototyping. Karabo’s GUI features an intuitive, coding-free control panel builder. This allows non-software engineers to create synoptic control views. This contribution introduces the Karabo Control System out of the view of application users and software developers. Emphasis is given to Karabo’s asynchronous Python environment. We share experience of running the European XFEL using a clean-sheet developed control system, and discuss the availability of the system as free and open source software.

At CERN, work has been undertaken since 2019 to transition from running Accelerator controls software on bare metal to running in an orchestrated, containerized environment. This will allow engineers to optimise infrastructure cost, to improve disaster recovery and business continuity, and to streamline DevOps practices along with better security. Container adoption requires developers to apply portable practices including aspects related to persistence integration, network exposure, and secrets management. It also promotes process isolation and supports enhanced observability. Building on containerization, orchestration platforms (such as Kubernetes) can be used to drive the life cycle of independent services into a larger scale infrastructure. This paper describes the strategies employed at CERN to make a smooth transition towards an orchestrated containerised environment and discusses the challenges based on the experience gained during an extended proof-of-concept phase.

B. Urbaniec, L. Burdzanowski, S.G. Gennaro
CERN, Meyrin, Switzerland

The CERN Accelerator Controls are comprised of various high-level services that work together to provide a highly available, robust, and versatile means of controlling the Accelerator Complex. Each service includes an API (Application Programming Interface) which is used both for service-to-service interactions, as well as by end-user applications. These APIs need to support interactions from heterogeneous clients using a variety of programming languages including Java, Python, C++, or direct HTTP/REST calls. This presents several technical challenges, including aspects such as reliability, availability and scalability. API usability is another important factor with accents on ease of access and minimizing the exposure to Controls domain complexity. At the same time, there is the requirement to efficiently and safely cater for the inevitable need to evolve the APIs over time. This paper describes concrete technical and design solutions addressing these challenges, based on experience gathered over numerous years. To further support this, the paper presents examples of real-life telemetry data focused on latency and throughput, along with the corresponding analysis. The paper also describes on-going and future API development.

This paper describes the requirements, design, and implementation of Role-Based Access Control (RBAC) for RHIC Complex. The system is being designed to protect from accidental, unauthorized access to equipment of the RHIC Complex, but it also can provide significant protection against malicious attacks. The role assignment is dynamic. Roles are primarily based on user id but elevated roles may be assigned for limited periods of time. Protection at the device manager level may be provided for an entire server or for individual device parameters. A prototype version of the system has been deployed at RHIC complex since 2022. The authentication is performed on a dedicated device manager, which generates an encrypted token, based on user ID, expiration time, and role level. Device managers are equipped with an authorization mechanism, which supports three methods of authorization: Static, Local and Centralized. Transactions with token manager take place ’atomically’, during secured set() or get() requests. The system has small overhead: ~0.5 ms for token processing and ~1.5 ms for network round trip. Only python based device managers are participating in the prototype system. Testing has begun with C++ device managers, including those that run on VxWorks platforms. For easy transition, dedicated intermediate shield managers can be deployed to protect access to device managers which do not directly support authorization.

The Square Kilometre Array (SKA) is an international effort to build two radio interferometers in South Africa and Australia, forming one Observatory monitored and controlled from global headquarters (GHQ) based in the United Kingdom at Jodrell Bank. The software for the monitoring and control system is developed based on the TANGO-controls framework, which provide a distributed architecture for driving software and hardware using CORBA distributed objects that represent devices that communicate with ZeroMQ events internally. This system runs in a containerised environment managed by Kubernetes (k8s). k8s provides primitive resource types for the abstract management of compute, network and storage, as well as a comprehensive set of APIs for customising all aspects of cluster behaviour. These capabilities are encapsulated in a framework (Operator SDK) which enables the creation of higher order resources types assembled out of the k8s primitives (\verb|Pods|, \verb|Services|, \verb|PersistentVolumes|), so that abstract resources can be managed as first class citizens within k8s. These methods of resource assembly and management have proven useful for reconciling some of the differences between the TANGO world and that of Cloud Native computing, where the use of Custom Resource Definitions (CRD) (i.e., Device Server and DatabaseDS) and a supporting Operator developed in the k8s framework has given rise to better usage of TANGO-controls in k8s.

MAX IV Laboratory, Lund University, Lund, Sweden

The motions at beamlines sometimes require components to move along non-trivial and non-linear paths. This type of motion can be achieved by combining several simple axes, typically linear and rotation actuators, and controlling them to perform synchronized motions along individual non-linear paths. A good example is the 10-meter-long spectrometer at MAX IV Veritas beamline, operating under the Rowland condition. The system consists of 6 linked axes that must maintain the position of detectors while avoiding causing any damage to the mechanical structure. The nonlinear motions are constructed as a trajectory through energy or focus space. The trajectory changes whenever any parameter changes or when moving through focus space at fixed energy instead of through energy space. Such changes result in automated generation and uploading of new trajectories. The motion control is based on parametric trajectory functionality provided by IcePAP. Scanning and data acquisition are orchestrated through Tango and Sardana to ensure full motion synchronization and that triggers are issued correctly.

PSI, Villigen PSI, Switzerland

The SLS-2.0 upgrade project comprises of a new storage ring and magnet lattice and will result in improved emittance and brightness by two orders of magnitude. Paired with these upgrades is a generational upgrade of the motion control system, away from VME based hardware and towards a more modern framework. For SLS-2.0 beamlines, the EtherCAT Motion Control (ECMC) open source framework has been chosen as the de-facto beamline motion control system for simple motion, analog/digital input/output and simple data collection. The ECMC framework comprises of a feature rich implementation of the EtherCAT protocol and supports a broad range of Beckhoff hardware, with the ability to add further EtherCAT devices. ECMC provides soft PLC functionality supported by the C++ Mathematical Expression Toolkit Library (ExprTk), which runs at a fixed frequency on the EtherCAT master at a rate up to the EtherCAT frame rate. This PLC approach allows for implementing complex motion, such as forward and backward kinematics of multi-positioner systems, i.e. roll, yaw, and pitch in a 5-axis mirror system. Additional logic can be loaded in the form of plugins written in C. Further work is ongoing to provide flexible Position Compare functionality at a frequency of 1 kHz coupled with event triggering as a way to provide a basic fly-scan functionality for medium performance applications with the use of standardized SLS-2.0 beamline hardware. We provide an overview of these and related ECMC activities currently ongoing for the SLS-2.0 project.

The Linac Coherent Light Source (LCLS) has been undergoing upgrades for several years now through at least two separate major projects: LCLS-II a DOE 403.13b project responsible for upgrading the accelerator, undulators and some front-end beam delivery systems, and the LCLS-II Strategic Initiative or L2SI project which assumed responsibility for upgrading the experiment endstations to fully utilize the new XFEL machine capabilities to be delivered by LCLS-II. Both projects included scope to design, install and commission a control system prepared to handle the risks associated with the tenfold increase in beam power we will eventually achieve. This paper provides an overview of the new control system architecture from the LCLS-II and L2SI projects and status of its commissioning.

Motion control systems at CERN often have challenging requirements, such as high precision in extremely radioactive environments with millisecond synchronization. These demanding specifications are particularly relevant for Beam Intercepting Devices (BIDs) such as the collimators of the Large Hadron Collider (LHC). Control electronics must be installed in safe areas, hundreds of meters away from the sensors and actuators while conventional industrial systems only work with cable lengths up to a few tens of meters. To address this, several years of R&D have been committed to developing a high precision motion control system. This has resulted in specialized radiation-hard actuators, new sensors, novel algorithms and actuator control solutions capable of operating in this challenging environment. The current LHC Collimator installation is based on off-the-shelf components from National Instruments. During the Long Shutdown 3 (LS3 2026-2028), the existing systems will be replaced by a new high-performance Sensors Acquisition and Motion Control system (SAMbuCa). SAMbuCa represents a complete, in-house developed, flexible and modular solution, able to cope with the demanding requirements of motion control at CERN, and incorporating the R&D achievements and operational experience of the last 15 years controlling more than 1200 axes at CERN. In this paper, the hardware and software architectures, their building blocks and design are described in detail.

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory has been operating for over 15 years and many electronic components are now obsolete and require replacement to assure reliability and sustainability. SNS uses stepper motors to control accelerator components throughout the facility including the cryomodule tuners, beam scrapers, and the primary and secondary stripper foils. The original motor controls were implemented with VME controllers, custom power supplies, and various types of motor drivers. As these components became less reliable and obsolete a new control solution was needed that could be applied to multiple motion control systems. Fast performance requirements are not crucial for these stepper motors, so the PLC technology was selected. The first system replaced was the Ring stripper foil control system and plans are underway to replace the beam scrapers. This paper provides an overview of the commercial off-the-shelf (COTS) hardware used to control stepper motors at SNS. Details of the design and challenges to convert a control system during short maintenance periods without disrupting beam operation will be covered in this paper.

The Tango HDB++ project is a high performance event-driven archiving system which stores data with micro-second resolution timestamps. HDB++ supports many different backends, including MySQL/MariaDB, TimeScaleDB (a time-series PostgreSQL extension), and soon SQLite. Building on its flexible design, latest developments made supporting new backends even easier. HDB++ keeps improving with new features such as batch insertion and by becoming easier to install or setup in a testing environment, using ready to use docker images and striving to simplify all the steps of deployment. The HDB++ project is not only a data storage installation, but a full ecosystem to manage data, query it, and get the information needed. In this effort a lot of tools were developed to put a powerful backend to its proper use and be able to get the best out of the stored data. In this paper we will present as well the latest developments in data extraction, from low level libraries to web viewer integration such as grafana. Pointing out strategies in use in terms of data decimation, compression and others to help deliver data as fast as possible.

As the volume and quantity of data continue to increase, the role of data management becomes even more crucial. It is essential to have tools that facilitate the management of data in order to manage the ever-growing amount of data. SciCat is a metadata catalogue that utilizes a NoSQL database, enabling it to accept heterogeneous data and customize it to meet the unique needs of scientists and facilities. With its API-centric architecture, SciCat simplifies the integration process with existing infrastructures, allowing for easy access to its capabilities and seamless integration into workflows, including cloud-based systems. The session aims to provide a comprehensive introduction of SciCat, a metadata catalogue started as a collaboration between PSI, ESS, and MAXIV, which has been adopted by numerous Research Infrastructures (RIs) worldwide. The presentation will delve into the guiding principles that underpin this project and the challenges that it endeavours to address. Moreover, it will showcase the features that have been implemented, starting from the ingestion of data to its eventual publication. Given the growing importance of the FAIR (Findable, Accessible, Interoperable, and Reusable) principles, the presentation will touch upon how their uptake is facilitated and will also provide an overview of the work carried out under the Horizon 2020 EU grant for FAIR.

Brookhaven National Laboratory’s Collider-Accelerator Department houses over 550 Front-End Computers (FECs) of varying specifications and resource requirements. These FECs provide operations-critical functions to the complex, and uptime is a concern among the most resource constrained units. Asynchronous data delivery is widely used by applications to provide live feedback of current conditions but contributes significantly towards resource exhaustion of FECs. To provide a balance of performance and efficiency, the Reflective system has been developed to support unrestricted use of asynchronous data delivery with even the most resource constrained FECs in the complex. The Reflective system provides components which work in unison to offload responsibilities typically handled by core controls infrastructure to hosts with the resources necessary to handle heavier workloads. The Reflective system aims to be a drop-in component of the controls system, requiring few modifications and remaining completely transparent to users and applications alike.

At the core of the Bluesky experimental control ecosystem the ophyd hardware abstraction, a consistent high-level interface layer, is extremely powerful for complex device integration. It introduces the device data model to EPICS and eases integration of alien control protocols. This paper focuses on the integration of the Sample Environment Communication Protocol (SECoP)* into the ophyd layer, enabling seamless incorporation of sample environment hardware into beamline experiments at photon and neutron sources. The SECoP integration was designed to have a simple interface and provide plug-and-play functionality while preserving all metadata and structural information about the controlled hardware. Leveraging the self-describing characteristics of SECoP, automatic generation and configuration of ophyd devices is facilitated upon connecting to a Sample Environment Control (SEC) node. This work builds upon a modified SECoP-client provided by the Frappy framework**, intended for programming SEC nodes with a SECoP interface. This paper presents an overview of the architecture and implementation of the ophyd-SECoP integration and includes examples for better understanding.

The European Spallation Source is one of the largest science and technology infrastructure projects being built today. The Control System at ESS is then essential for the synchronisation and day-to-day running of all the equipment responsible for the production of neutrons for the experimental programs. The standardised PLC platform for ESS to handle slower signal comes from Siemens*, while for faster data interchange with deterministic timing and higher processing power, from Beckoff/EtherCAT**. All the Control Systems based on the above technologies are integrated using EPICS framework***. We will present how the full stack integration from PLC to EPICS is done at ESS using our standard Configuration Management Ecosystem.

The SKA Project is a science mega-project whose mission is to build an astronomical observatory that comprises two large radio-telescopes: the SKA-Low Telescope, located in the Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory in Western Australia, with the observing range 50 to 350 MHz, and the SKA Mid Telescope, located in the Karoo Region, South Africa, with the observing range 350 MHz to 15 GHz. The SKA Global Headquarters is in the Jodrell Bank Observatory, near Manchester, UK. When completed, the SKA Telescopes will surpass existing radio-astronomical facilities not only in the scientific criteria such as sensitivity, angular resolution, and survey speed, but also in the number of receptors and the range of the observing and processing modes. The Observatory, and each of the Telescopes, will be delivered in stages, thus supporting incremental development of the collecting area, signal and data processing capacity, and the observing and processing modes. Unlike scientific capability, which, in some cases, may be delivered in the late releases, the control system is required from the very beginning to support integration and verification. Development of the control system to support the first delivery of the Telescopes (Array Assembly 0.5) is well under way. This paper describes the SKA approach to the development of the Telescope Control System, and discusses opportunities and challenges resulting from the distributed development and staged approach to the Telescope construction.

FAIR Data of Physical and Digital Beamlines

HZB, Berlin, Germany

Simulations play a crucial role in instrument design, as a digital precursor of a real-world object they contain a comprehensive description of the setup. Unfortunately, this digital representation is often neglected once the real instrument is fully commissioned. To preserve the symbiosis of simulated and real-world instrument beyond commissioning we connect the two worlds through the instrument control software. The instrument control simultaneously starts measurements and simulations, receives feedback from both, and directs (meta)data to a NeXus file - a standard format in photon and neutron science. The instrument section of the produced NeXus file is enriched with detailed simulation parameters where the current state of the instrument is reflected by including real motor positions such as incorporating the actual aperture of a slit system. As a result, the enriched instrument description increases the reusability of experimental data in sense of the FAIR principles. The data is ready to be exploited by machine-learning techniques, such as for predictive maintenance applications as it is possible to perform simulations of a measurement directly from the NeXus file. The realization at the Aquarius beamline * at Bessy II in connection with the Ray-UI simulation software ** and RayPyNG API *** serves as a prototype for a more general application.

At the European Spallation Source, over 300 MicroTCA systems will be deployed over the accelerator, target area and instruments. Covering integrations for RF, Beam Instrumentation, Machine Protection and Timing Distribution systems, ESS has developed a method to standardise the deployment of the basic MicroTCA system configuration using a combination of Python scripts and Ansible playbooks with a view to ensure long-term maintainability of the systems and future upgrades. By using Python scripts to setup, the Micro Carrier Hub (MCH) registering it on the network and update the firmware to our chosen version, and Ansible playbooks to register the Concurrent Technologies CPU on the ESS network and install the chosen Linux OS before a second playbook installs the ESS EPICs Environment (E3) ensures all new systems have identical setup procedures and have all the necessary packages before the on-site integration is started.

The timing system at the ISIS Neutron and Muon source has been operating in its current iteration since 2008. Machine timing is handled by the Central Timing Distributor (CTD) which transmits various timing signals to ISIS accelerator equipment over RS-422 compliant timing buses. The nature of these timing signals has not changed since ISIS first delivered neutrons in 1984, and this paper will look at how an event-based timing system can be employed in the next generation of timing system for ISIS. A new timing system should allow for the distribution of events, triggers and timestamps, provide an increase in timing resolution and be fully backwards compatible with the current timing frame. The new Digitised Waveform System (DWS) at ISIS supports White Rabbit (WR). There is an available WR network which can be used to investigate a new timing system based on WR technology. Conclusions will be drawn from installing this new system in parallel with the current timing system; a comparison between the systems, alternatives, and next steps will be discussed.

The European Spallation Source (ESS) will be a cutting-edge research facility that uses neutrons to study the properties of materials. This paper presents the timestamping strategy employed in the neutron instruments of the ESS, to enable efficient data correlation across subsystems and between different sources of experiment data. ESS uses absolute timestamps for all data and a global source clock to synchronize and timestamp data at the lowest appropriate level from each subsystem. This way we control the impact of jitter, delays and latencies when transferring experiment data to the data storage. ESS utilizes three time synchronisation technologies. The Network Time Protocol (NTP) providing an expected accuracy of approximately 10 milliseconds, the Precision Time Protocol (PTP) delivering roughly 10 microsecond accuracy, and hardware timing using Microreseach Finland (MRF) Event Receivers (EVR) which can reach 10 nanoseconds of accuracy. Both NTP and PTP rely on network communication using common internet protocols, while the EVRs use physical input and output signals combined with timestamp latching in hardware. The selection of the timestamping technology for each device and subsystem is based on their timestamp accuracy requirements, available interfaces, and cost requirements. This paper describes the choice of method used for different device types, like neutron choppers, detectors or sample environment equipment and covers some details of the implementation and characterisation.

FRIB Beam Power Ramp Process Checker at Chopper Monitor

Funding: Work supporting the U.S. Dept. of Energy Office of Science under Cooperative Agreement DE-SC0023633
Chopper in the low energy beam line is a key ele-ment to control beam power in FRIB. As appropriate functioning of chopper is critical for machine protec-tion for FRIB, an FPGA-based chopper monitoring system was developed to monitor the beam gated pulse at logic level, deflection high voltage level, and in-duced charge/discharge current levels, and shut off beam promptly at detection of a deviation outside tolerance. Once FRIB beam power reaches a certain level, a cold start beam ramp mode in which the pulse repetition frequency and pulse width are linearly ramped up becomes required to mitigate heat shock to the target at beam restart. Chopper also needs to gen-erate a notch in every machine cycle of 10 ms that is used for beam diagnostics. To overcome the challeng-es of monitoring such a ramping process and meeting the response time requirement of shutting off beam, two types of process checkers, namely, monitoring at the pulse level and monitoring at the machine cycle level, have been implemented. A pulse look ahead algorithm to calculate the expected range of frequency dips and rises was developed, and a simplified mathe-matical model suitable for multiple ramp stages was built to calculate expected time parameters of accumu-lated pulse on time within a given machine cycle. Both will be discussed in detail in this paper, followed by simulation results with FPGA test bench and actual instrument test results with the beam ramp process.

This paper presents a comprehensive overview of the motion control systems employed within the neutron science user facilities at Oak Ridge National Laboratory (ORNL). The Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR) at ORNL have a total of 35 neutron beam lines with numerous motors for mo-tion control. The motion systems vary in complexity from a linear sample positioning stage to multi-axis end stations. To enhance the capabilities of these motion systems, a concerted effort has been made to establish standardized hardware and flexible software that improve performance, increase reliability and provide the capability for automated experiments. The report discusses the various motion controllers used, the EPICS-based IOCs (Input Output Controllers), high-level motion software, and plans for ongoing upgrades and new projects.

Using ArUco Codes for Beam Spot Analysis with a Camera at an Unknown Position

HZB, Berlin, Germany

Measuring the focus size and position of an X-ray beam at the interaction point in an synchrotron beamline is a critical parameter that is used when planning experiments and when determining if a beamline is achieving it’s design goals. Commonly this is performed using a dedicated UHV "focus chamber" comprising a fluorescent screen at an adjustable calibrated distance from the mounting flange and a camera on the same axis as the beam. Having to install a large piece of hardware makes regular checks prohibitively time consuming. A fluorescent screen can be mounted to a sample holder and moved using a manipulator in the existing end-station and a camera pointed at this to show a warped version of the beam spot at the interaction point. The warping of the image is caused by the relative position of the camera to the screen, which is difficult to determine and can change and come out of camera focus as the manipulator is moved. This paper proposes a solution to this problem using ArUco codes printed onto a fluorescent screen which provide a reference in the image. Reference points from the ArUco codes are recovered from an image and used to correct warping and provide a calibration in real time using an EPICS AreaDetector plugin using OpenCV. This analysis is presently in commissioning and aims to characterise the beam spots at the dual-colour beamline of the EMIL laboratory at BESSY II.

LImA* is a framework born at the ESRF for 2D Data Acquisition (DAQ), basic Online Data Analysis (ODA) and processing with high-throughput detectors. While in production for 15 years in several synchrotron facilities, the ever-increasing detector frame rates make more and more difficult performing DAQ & ODA tasks on a single computer**. LImA2 is designed to scale horizontally, using multiple hosts for DAQ & ODA. This enables more advanced strategies for data feature extraction while keeping a low latency. LImA2 separates three functional blocks: detector control, image acquisition, and data processing. A control process configures the detector, while one or more receiver processes perform the DAQ and ODA, like the generation of fast feedback signals. The detectors currently supported in LImA2 are the PSI/Jungfrau, the ESRF/Smartpix and the Dectris/Eiger2. The former performs pixel assembly and intensity correction in GPU; the second exploits RoCE capabilities; and the latter features dual threshold, multi-band images. Raw data rates up to 8 GByte/s can be handled by a single computer, scalable if necessary. In addition to a classic processing, advanced pipelines are also implemented. A Serial-MX/pyFAI*** pipeline extracts diffraction peaks in GPU in order to filter low quality data. NVIDIA GPUDirect is used by a third pipeline providing 2D processing with remarkable low latency. IBM Power9 optimizations like the NX GZIP compression and the PCI-e multi-host extension are exploited.

DLS, Oxfordshire, United Kingdom

At Diamond Light Source, several Macromolecular Crystallography (MX) beamlines focus on, or include, completely automated data collection. This is used primarily for high throughput collection on samples with known or partially known structures, for example, screening a protein for drug or drug fragment interactions. The automated data collection routines are currently built on legacy experiment orchestration software which includes a lot of redundancy originally implemented for safety when human users are controlling the beamline, but which is inefficient when the beamline hardware occupies a smaller number of known states. Diamond is building its next generation, service-based, Data Acquisition Platform, Athena, using NSLSII’s Bluesky experiment orchestration library. The Bluesky library facilitates optimising the orchestration of experiment control by simplifying the work necessary to parallelise and reorganise the steps of an experimental procedure. The MX data acquisition team at Diamond is using the Athena platform to increase the possible rate of automated MX data collection both for immediate use and in preparation to take advantage of the upgraded Diamond-II synchrotron, due in several years. This project, named Hyperion, will include sample orientation and centring, fluorescence scanning, optical monitoring, collection strategy determination, and rotation data collection at multiple positions on a single sample pin.

The evaluation of the focus produced by a KB (Kirkpatrick-Baez) mirror system is a challenging endeavor. In MOGNO (Micro and nano tomography) beamline’s case at Sirius, the KB was designed to produce a focus of 150x150 nm2, requiring a setup to evaluate the mirrors’ alignment in a timely manner. The developed diagnostic system is comprised of a stack of three linear inertia drive piezo stages and a fluorescence detector, acquiring data via hardware-triggered mesh scans. In the piezo stack, the stages are mounted along the X (horizontal, perpendicular to the beam path), Z (along the beam path) and YZ beamline directions. Moreover, the fact that a stage is placed at an angle requires the use of a kinematic transformation when scaning the focus along the Y axis, while the X axis scan can be done with a pure motion. The mesh scan can be diveded in two parts: hardware triggered line scan acquisition along X or Y and software triggered steps along Z between scans. In this manner, the control is done via a collection of low-level controller macros and Python scripts, such that during the scans, the piezo controllers communicate with each other and the detector via digital pulses, orchestrated by the in-house TATU (Timing and Trigger Unit) software*, reducing dead time between acquisition points. The proposed system proved to be reliable to acquire beam profiles, providing caustics in both horizontal and vertical directions. Currently, the acquired focus caustics indicate that the main source has a size of approximately 480x500 nm2.

Video Compression for areaDetector

detector, neutron, scattering, EPICS

B.A. Sobhani
ORNL, Oak Ridge, Tennessee, USA

At neutron sources such as SNS and HFIR, neutrons collide with neutron detectors at a much lower rate than light would for an optical detector. Additionally, the image typically does not pan or otherwise move. This means that the incremental element-by-element differences between frames will be small. This makes neutron imaging data an ideal candidate for video-level compression where the incremental differences between frames are compressed and sent, as opposed to image-level compression where the entire frame is compressed and sent. This paper describes an EPICS video compression plugin for areaDetector that was developed at SNS.

A new generation of Qt graphical components, namely cumbia-qtcontrols-ng is under development at ELETTRA. A common engine allows each component to be rendered on traditional QWidgets and scalable QGraphicsItems alike. The latter technology makes it possible to integrate live controls with static SVG in order to realize any kind of synoptic with touch and scaling capabilities. A pluggable zoomer can be installed on any widget or graphics item. Apply numeric controls, Cartesian and Circular (Radar) plots are the first components realized.

In order to characterize the critical-current density of low temperature superconductors such as niobium¿titanium (NbTi) and niobium¿tin (Nb₃Sn) or high temperature superconductors such as magnesium-diboride MgB₂ or Rare-earth Barium Copper Oxide REBCO tapes, a wide range of custom instruments and interfaces are used. The critical current of a superconductor depends on temperature, magnetic field, current and strain, requiring high precision measurements in the nano Volt range, well-synchronized instrumentation, and the possibility to quickly adapt and replace instrumentation if needed. The micro-service based application presented in this paper allows operators to measure a variety of analog signals, such as the temperature of the cryostats and sample under test, magnetic field, current passing through the sample, voltage across the sample, pressure, helium level etc. During the run, the software protects the sample from quenching, controlling the current passed through it using high-speed field programmable gate array (FPGA) systems on Linux Real-Time (RT) based PCI eXtensions controllers (PXIe). The application records, analyzes and reports to the external Oracle database all parameters related to the test. In this paper, we describe the development of the micro-service based control system, how the interlocks and protection functionalities work, and how we had to develop a multi-windowed scalable acquisition application that could be adapted to the many changes occurring in the test facility.

The EBS storage ring control system is presently paired with an electron beam dynamics digital twin (the EBS control system simulator, EBSS*). The EBSS reproduces many of the beam dynamics related quantities relevant for machine operation. This digital twin is used for the preparation and debug of software to deploy for operation. The EBSS is presently working only for the main storage ring and it is not directly connected to the machine operation but works in parallel and on demand. We present here the steps taken towards an on-line continuous use of the EBSS to monitor the evolution of not directly observable parameters such as beam optics.

EPICS Integration for Rapid Control Prototyping Hardware from Speedgoat

EPICS, hardware, real-time, interface

1317

L. Rossa, M. Brendike
HZB, Berlin, Germany

To exploit the full potential of fourth generation Synchrotron Sources, new beamline instrumentation is increasingly developed with a mechatronics approach. [*,**,***] Implementing this approach raises the need for Rapid Control Prototyping (RCP) and Hardware-In-the-Loop (HIL) simulations. To integrate such RCP and HIL systems into every-day beamline operation we developed an interface from a Speedgoat real-time performance machine - programmable via MATLAB Simulink - to EPICS. The interface was developed to be simple to use and still flexible. The Simulink software developer uses dedicated Simulink-blocks to export model information and real-time data into structured UDP Ethernet frames. The corresponding EPICS IOC listens to the UDP frames and auto-generates a corresponding database file to fit the data-stream from the Simulink model. The EPICS IOC can run on either a beamline measurement PC or to keep things spatially close on a mini PC (such as a Raspberry Pi) attached to the Speedgoat machine. An overview of the interface idea, architecture and implementation, together with some simple examples will be presented.

Funding: The project SECoP@HMC receives funding by the Helmholtz Association’s Initiative and Networking Fund (IVF).
The integration of sample environment (SE) equipment in x-ray and neutron experiments is a complex challenge both in the physical world and in the digital world. Dif-ferent experiment control software offer different interfac-es for the connection of SE equipment. Therefore, it is time-consuming to integrate new SE or to share SE equipment between facilities. To tackle this problem, the International Society for Sample Environment (ISSE, [1]) developed the Sample Environment Communication Protocol (SECoP) to standardize the communication between instrument control software and SE equipment [2]. SECoP offers, on the one hand, a generalized way to control SE equipment. On the other hand, SECoP holds the possibility to transport SE metadata in a well-defined way. In addition, SECoP provides machine readable self-description of the SE equipment which enables a fully automated integration into the instrument control soft-ware and into the processes for data storage. Using SECoP as a common standard for controlling SE equipment and generating SE metadata will save resources and intrinsi-cally give the opportunity to supply standardized and FAIR data compliant SE metadata. It will also supply a well-defined interface for user-provided SE equipment, for equipment shared by different research facilities and for industry. In this article will show how SECoP can help to provide a meaningful and complete set of metadata for SE equipment and we will present SECoP and the SECoP@HMC project supported by the Helmholtz Metadata Collaboration.

In the last beam times, operations reported a lack of performance and long waiting times when performing simple changes of the machines’ settings. To ensure performant operation of the future Facility for Antiproton and Ion Research (FAIR), the "Task Force Performance" (TFP) was formed in mid-2020, which aimed at optimizing all involved Control System components. Baseline measurements were recorded for different scenarios to compare and evaluate the steps taken by the TFP. These measurements contained data from all underlying systems, from hardware device data supply over network traffic up to user interface applications. Individual groups searched, detected and fixed performance bottlenecks in their components of the Control System stack, and the interfaces between these individual components were inspected as well. The findings are presented here.

This paper presents online anomaly detection on low-level radio frequency (LLRF) cavities running on FLASH/XFEL DAQ system*. The code is run by a DAQ Middle Layer (ML) server, which has on-line access to all collected data. The ML server executes a Python script that runs a pre-trained machine learning model on every shot in the FLASH/XFEL machine. We discuss the challenges associated with real-time anomaly detection due to high data rates generated by RF cavities, and introduce a DAQ system pipeline and algorithms used for online detection on arbitrary channels in our control system. The system’s performance is evaluated using real data from operational RF cavities. We also focus on the DAQ monitor server’s features and its implementation.

At DESY, the PETRA III synchrotron light source upgrade towards a fourth-generation, low-emittance machine PETRA IV is being pursued. The realisation of the new machine requires a complete redesign of the timing system, as the beam quality and beam control requirements will change significantly. The new timing system must generate and distribute facility-wide precise clocks, trigger signals, trigger events and beam-synchronous information. The design of the main hardware components will be based on the MTCA.4 standard, which has become a well-established platform at DESY and successfully been in use with DESY FEL’s MTCA.4-based timing systems for almost a decade now. This paper presents and discusses the PETRA IV timing system overall concept and functionality and its hardware components development status.

An EPICS-based control system typically consists of many individual IOCs, which can be distributed across many computers in a network. Managing hundreds of deployed IOCs, keeping track of where they are running, and providing operators with basic interaction capabilities can easily become a maintenance nightmare. At the Institute for Beam Physics and Technology (IBPT) of the Karlsruhe Institute of Technology (KIT), we operate separate networks for our accelerators KARA and FLUTE and use the Salt Project to manage the IT infrastructure. Custom Salt states take care of deploying our IOCs across multiple servers directly from the code repositories, integrating them into the host operating system and monitoring infrastructure. In addition, this allows the integration into our GUI in order to enable operators to monitor and control the process for each IOC without requiring any specific knowledge of where and how that IOC is deployed. Therefore, we can maintain and scale to any number of IOCs on any numbers of hosts nearly effortless. This paper presents the design of this system, discusses the tools and overall setup required to make it work, and shows off the integration into our GUI and monitoring systems.

Scientific instruments at the European X-Ray Free Electron Laser Facility (EuXFEL) comprises of a large variety of equipment, ranging from controllers, motors and encoders to valves. It is a false assumption that once a specific equipment had been procured and integrated, that no further attention is required. Reality is much more complex and incorporates various stages across the entire equipment life-cycle. This starts from the initial selection, standardization of the equipment, procurement, integration, tracking, spare part management, maintenance, documentation of interventions and repair, replacement and lastly, decommissioning. All aspects of such a life-cycle management are crucial in order to ensure safe and reliable operation across the life time of the equipment, whether it be five years, twenty years, or longer. At EuXFEL, many aspects of the described life-cycle management are already carried out with dedicated tools. However some aspects rely on manual work, which requires significant effort and discipline. This contribution aims to provide an overview of the requirements, and the ongoing efforts to develop and establish a complete life-cycle management at the EuXFEL.

The European XFEL is an X-ray free-electron laser (FEL) facility located in Schenefeld, in the vicinity of Hamburg, Germany. With a total length of 3.4 kilometers, the facility provides seven scientific instruments with extremely intense X-ray flashes ranging from the soft to the hard X-ray regime. The dimension of the beam transport and the technologies used to make this X-ray FEL unique have led to the design and buildup of a challenging and adaptable control system based on a Programmable Logic Controller (PLC). Six successful years of user operation, which started in September 2017, have required constant development of the beam transport in order to provide new features and improvements for the scientific community to perform their research activities. The framework of this contribution is focused on the photon beamline, which starts at the undulator section and guides the X-ray beam to the scientific instruments. In this scope, the control system topology and this adaptability to integrate new devices through the PLC Management System (PLCMS) are described. In 2022, a new distribution mirror was installed in the SASE3 beam transport system to provide photon beams to the seventh and newest scientific instrument, named Soft X-ray Port (SXP). To make the scope of this paper more practical, this new installation is used as an example. The integration in the actual control system of the vacuum devices, optic elements, and interlock definition are described.

The Karabo software framework* is a pluggable, distributed control system that offers rapid control feedback to meet the complex requirements of the European X-ray Free Electron Laser facility. Programmable Logic Controllers (PLC) using Beckhoff technology are the main hardware control interface system within the Karabo Control System. The communication between Karabo and PLC currently uses an in-house developed TCP/IP protocol using the same port for operational-related communications and self-description (the description of all available devices sent by PLC). While this simplifies the interface, it creates a notable load on the client and lacks certain features, such as a textual description of each command, property names coherent with the rest of the control system as well as state-awareness of available commands and properties**. To address these issues and to improve user experience, the new implementation will provide a comprehensive self-description, all delivered via a dedicated TCP port and serialized in a JSON format. A Python Asyncio implementation of the Karabo device responsible for message decoding, dispatching to and from the PLC, and establishing communication with relevant software devices in Karabo incorporates lessons learned from prior design decisions to support new updates and increase developer productivity.

EuXFEL, Schenefeld, Germany

The European XFEL (EuXFEL) scientific facility relies heavily on the SCADA control system Karabo* to configure and control a plethora of hardware devices. In this contribution a software solution for automatic configuration of collections of like Karabo devices is presented. Parameter presets for the automatic configuration are stored in a central database. In particular, the tool is used in the configuration of collections of single-axis motors, which is a recurring task at EuXFEL. To facilitate flexible experimental setup, motors are moved within the EuXFEL and reused at various locations in the operation of scientific instruments. A set of parameters has to be configured for each motor controller, depending on the controller and actuator model attached to a given programmable logic controller terminal, and the location of the motor. Since manual configurations are time-consuming and error-prone for large numbers of devices, a database-driven configuration of motor parameters is desirable. The software tool allows to assign and apply stored preset configurations to individual motors. Differences between the online configurations of the motors and the stored configurations are highlighted. Moreover, the software includes a "locking" feature to prevent motor usage after unintentional reconfigurations, which could lead to hardware damage.

In the last years a thorough approach has been adopted to address the aging and the variability of control system platforms at Elettra Sincrotrone Trieste. The second generation of an in-house built operating system, named Voltumna Linux, which is based on immutable image approach, is now ready for production, supporting a number of commercial-off-the-shelf embedded systems. Moreover, the same approach is perfectly suitable for rack-mount servers, with large memory support, that often require the inclusion of third party or closed source packages. Being entirely based on Git for revision control, Voltumna Linux brings in a number of advantages, such as reproducibility of the product, ease of upgrading or downgrading complete systems, centralized management and deployment of the user software to name a few.

INFN/LNL, Legnaro (PD), Italy

The superconductive quarter wave cavities hadron Lin-ac ALPI is the final acceleration stage at the Legnaro National Laboratories and it is going to be used as re-acceleration line of the radioactive ion beams for the SPES (Selective Production of Exotic Species) project. The Linac was designed in ’90s with the available techniques and it was one of the peak technologies of this kind in Europe at those times, controls included. In the last decade, controls related to all the functional systems composing the accelerator have been ungraded to an EPICS-based solution. This upgrade has given us the opportunity to design and test new possible solutions for automatic beam transport. The work described in this paper is based on the experience and results (in terms of time, costs, and manpower) obtained using Particle Swarm Optimization (PSO) techniques for beam transport optimization applied to the ALPI accelerator. Due to the flexibility and robustness of this method, this tool will be extended to other parts of the facility.

M. Montis, F. Gelain, M.G. Giacchini
INFN/LNL, Legnaro (PD), Italy

During the last decade, the control system employed for ALPI and PIAVE Accelerators was upgraded to the new EPICS-based framework as part of the new standards adopted in the SPES project in construction in Legnaro. The actual control for beam transport was fully completed in 2015 and it has been in production since that year. Due to the power supply upgrade and to optimize costs and maintenance time, the original controllers based on in-dustrial PCs were substituted with dedicated serial-over-ethernet devices and Virtual Machines (VMs). In this work we will describe the solution designed and imple-mented for ALPI-PIAVE accelerators.

European Spallation Source (ESS) will be a neutron source using proton beam Linac of expected 5MW beam power. Designed and implemented by INFN-LNL, the Drift Tube Linac (DTL) control system is based on EPICS framework as indicated by the Project Requirements. This document aims to describe the results of the first part of the control system commissioning stage in 2022, where INFN and ESS teams were involved in the final tests on site. This phase was the first step toward a complete de-ployment of the control system, where the installation was composed by three sequential stages, according to the apparatus commissioning schedule. In this scenario, the firsts Site Acceptance Test (SAT) and Site Integrated Test (SIT) were crucial, and their results were the mile-stones for the other stages: the lessons learned can be important to speed up the future integration, calibration, and tuning of such a complex control system.

Currently, SuperKEK has network-based systems such as trigger delivery, bucket selection, abort system, beam permission, and distributed DAQ, all of which are operated as separate systems. The White Rabbit (WR) has extraordinary multi-functionality when combined with the modules already developed, so it is possible that in the future all systems could be operated in a WR network. This would lead to a reduction in human, time, and financial costs. We constructed a beam gate, which is a part of the beam permission system, on a trial basis using WR. These trigger deliveries need to be interlocked. The trigger delivery to the electron gun has a specification that the next trigger delivery is turned ON/OFF after receiving the ON/OFF signal at any given timing. For the above reasons, the delay time from the receipt of the ON/OFF signal from the electron gun is not a fixed value, making it difficult to interlock with the trigger delivery of other devices. By turning on/off the trigger delivery using a precisely time-synchronized WR, the ON/OFF of the trigger delivery of all devices could be correctly interlocked.

Introduction of the Ethernet-Based Field Networks to Inter-Device Communication for RIBF Control System

EPICS, Ethernet, network, PLC

RIKEN Nishina Center, Wako, Japan

Internet Protocol (IP) networks are widely used to remotely control measurement instruments and controllers. In addition to proprietary protocols, common commands such as the standard commands for programmable instruments (SCPI) are used by manufacturers of measuring instruments. Many IP-network-based devices have been used in RIBF control systems constructed using the experimental physics and industrial control system (EPICS); these are commercial devices designed and developed independently. EPICS input/output controllers (IOCs) usually establish socket communications to send commands to IP-network-based devices. However, in the RIBF control system, reconnection between the EPICS IOC and the device is often not established after the loss of socket communication due to an unexpected power failure of the device or network switch. In this case, it is often difficult to determine whether the socket connection to the EPICS IOC is broken even after checking the communication by pinging. Using Ethernet as the field network in the physical layer between the device and EPICS IOC can solve these problems. Therefore, we are considering the introduction of field networks such as EtherCAT and Ethernet/IP, which use Ethernet in the physical layer. In the implementation of the prototype system, EPICS IOCs and devices are connected via EtherCAT and Soft PLCs are run on the machine running EPICS IOCs for sequence control.

At High Energy Photon Source (HEPS), a multi-user virtual accelerator system has been developed for testing the high-level application (HLA) and simulating the effects of various errors on the results of beam commissioning. The virtual accelerator is based on the Pyapas development framework for HLA and is designed using a client/server (C/S) architecture. It uses Ocelot with custom multipole field models for physical calculations and supports error simulation for various magnet and beam instrumentation and diagnostics devices. Calculation results are sent externally through the EPICS PV channel. The multi-user virtual accelerator system was developed to meet the needs of different users within the same network segment who need to simultaneously call the virtual accelerator for software debugging and simulation research. Each user can open a unique virtual accelerator without affecting others, and can also start different virtual accelerators for different research content. The number of virtual accelerators opened is not limited. The operation of the entire virtual accelerator system can be easily switched on and off like opening an app, greatly facilitating user use. This article provides a detailed description of the design concept and implementation of the multi-user virtual accelerator system.

The beam commissioning of the Linac at High Energy Photon Source (HEPS) started on March 9th this year. High-level applications (HLAs) based on Pyapas were successfully applied to the beam commissioning. To meet the beam commissioning requirements of the Linac, a series of HLAs were developed, including physics-based control application, PR target data analysis application, emittance measurement application, energy and energy spread measurement application, acceleration phase scanning application, BBA and feedback orbit correction application. Before applying these applications to real beam commissioning, they were tested thoroughly on a virtual accelerator to ensure the correctness of the algorithms and the stability of the application operation. Thanks to the repeated testing on the virtual accelerator, the HLAs of the Linac performed well after being put online, helping the beam commissioning operators to quickly achieve the full-line transmission of the beam and optimize the parameters to the expected values in a short time. This paper will provide a detailed introduction to the application of the relevant HLAs in the Linac beam commissioning at HEPS.

This paper describes the design and implementation of the control system for the ForMAX beamline at the MAX IV synchrotron. MAX IV is a Swedish national laboratory that houses one of the brightest synchrotron light sources in the world. ForMAX is one of the beamlines at MAX IV and is funded by the Knut and Alice Wallenberg Foundation and Swedish industry via Treesearch. To meet the specific demands of ForMAX, a new control system was developed using the TANGO Controls and Sardana frameworks. Using these frameworks enables seamless integration of hardware and software, ensuring efficient and reliable beamline operation. The control system was designed to support a variety of experiments, including multiscale structural characterization from nanometer to millimeter length scales by combining full-field tomographic imaging, small- and wide-angle X-ray scattering (SWAXS), and scanning SWAXS imaging in a single instrument. The system allows for precise control of the beam position, energy, intensity, and sample position. Furthermore, the system provides real-time feedback on the status of the experiments, allowing for adjustments to be made quickly and efficiently. In conclusion, the design and implementation of the control system for the ForMAX beamline at the MAX IV synchrotron has resulted in a highly flexible and efficient experimental station. TANGO Controls and Sardana have allowed for seamless integration of hardware and software, enabling precise and reliable control of the beamline for a wide range of experiments.

SARAO, Cape Town, South Africa

The 64-dish MeerKAT radio telescope, constructed in South Africa, became the largest and most sensitive radio telescope in the Southern Hemisphere until integrated with the Square Kilometer Array (SKA). Our Control and Monitoring system for Radio Astronomy Project such as MeerKAT produces a lot of data and logs that require proper handling. Viewing and analysis to trace and track system issues and as well as investigate technical software issues require one to go back in time to look for event occurrence. We therefore deployed an ELK software stack ( Elasticsearch, Kibana, Logstash) using Ansible in order to have the capability to aggregate system process logs. We deploy the stack as a cluster comprising lxc containers running inside a Proxmox Virtual Environment using Ansible as a software deployment tool. Each container in the cluster performs cluster duties such as deciding where to place index shards and when to move them. Each container is a data node that makes up the heart of the cluster. We deploy the stack as a cluster for load balancing purposes. Logstash ingests ,transforms and sends the data to the Kibana Graphical User Interface for visualization. Elasticsearch indexes, analyzes, and searches the ingested data into Kibana and our Operations Team and other system users can visualize and analyze these logs on the Kibana GUI frontend.

Sardana Suite is an open-source scientific SCADA solution used in synchrotron light beamlines at ALBA, DESY, MAXIV and SOLARIS and in laser labs at MBI-Berlin. It is formed by Sardana and Taurus - both mature projects, driven by a community of users and developers for more than 10 years. Sardana provides a low level interface to the hardware, middle level abstractions and a sequence engine. Taurus is a library for developing graphical user interfaces. Sardana Suite uses client - server architecture and is built on top of TANGO. As a community, during the last few years, on one hand we were focusing on improving user experience, especially in terms of reliability and performance and on the other hand renewing the dependency stack. The system is now more stable, easier to debug and recover from a failure. An important effort was put in profiling and improving performance of Taurus applications startup. The codebase has been migrated to Python 3 and the plotting widgets were rewritten with pyqtgraph. This didn’t prevent us from delivering new features, like for example the long-awaited configuration tools and format based on YAML which is easy and intuitive to edit, browse, and track historical changes. Now we conclude this phase in the project’s lifetimes and are preparing for new challenging requirements in the area of continuous scans like higher data throughput and more complex synchronization configurations. Here we present the status report and the future roadmap.

The Low Level Radio Frequency (LLRF) system is an important part of a Spallation Source facility as ESS. LLRF is commonly used with many different setups depending on the aim: preparation, calibration, conditioning, commission and others. These different setups are strongly connected to another important system on accelerators: the Timing System. This proceeding presents how at ESS we implemented the integration between LLRF and Timing systems on the control system scope. The integration of these two systems provides different and important features as: allow different ways to trigger the RF system (synced or not to other systems), define how the RF output will be defined (based on the features of the expected beam), re-configure LLRF depending on the timing setup and more. This integration was developed on both ends, LLRF and timing, and is mostly concentrated on the control system layer based on EPICS. Dealing with the different scenarios, synchronicity and considering all the software, hardware and firmware involved are some of the challenges of this integration. The result of this work was used during the ESS accelerator commissioning in 2022 and will be used on next ESS accelerator commissioning in 2023.

The European Spallation Source (ESS) is adopting innovative data acquisition and analysis methods using global timestamping for neutron scattering research. This study characterises the timing accuracy and reliability of the instrument control system by examining an integrated motion and fast detection system. We designed an experimental apparatus featuring a motion axis controlled by a Beckhoff programmable logic controller (PLC) using TwinCAT 3 software. The encoder readback is timestamped in the PLC, which is time-synchronised with the ESS master clock via a Microresearch Finland event receiver (EVR) using Precision Time Protocol (PTP). We repeatedly scanned the motor between known positions at different speeds. The system was characterised by correlating the position and timestamp recorded by the PLC with independent information using a fast optical position sensor read out directly by the MRF system. The findings of this study provide a good benchmark for the upcoming experiments in neutron scattering research at ESS and should be interesting for those aiming to build similar setups.

This paper describes several control system test auto-mation frameworks for the control systems at the Europe-an Spallation Source (ESS), a cutting-edge research facili-ty that generates neutron beams for scientific experi-ments. The control system is a crucial component of ESS, responsible for regulating and monitoring the facility’s complex machinery, including a proton accelerator, target station, and several neutron instruments. The traditional approach to testing control systems largely relies on manual testing, which is time-consuming and error-prone. To enhance the testing process, several different test automation frameworks have been devel-oped for various types of applications. Some of these frameworks are integrated with the ESS control system, enabling automated testing of new software releases and updates, as well as regression testing of existing func-tionality. The paper provides an overview of the various automa-tion frameworks in use at ESS, including their architec-ture, tools, and development techniques. It discusses the benefits of the different frameworks, such as increased testing efficiency, improved software quality, and reduced testing costs. The paper concludes by outlining future development directions.

European Organization for Nuclear Research (CERN), Geneva, Switzerland

The Power Trigger Controller (PTC) of the LHC Beam Dumping System (LBDS) is in charge of the control and supervision of the Power Trigger Units (PTU), which are used to trigger the conduction of the 50 High-Voltage Pulsed Generators (HVPG) of the LBDS kicker magnets. This card is integrated in an Industrial Control System (ICS) and has the double role of controlling the PTU operating mode and monitoring its status, and of supervising the LBDS triggering and re-triggering systems. As part of the LBDS consolidation during the LHC Long Shutdown 2 (LS2), a new PTC card was designed, based on a System-on-Chip (SoC) implemented in an FPGA. The FPGA contains an ARM Cortex-M3 softcore processor and all the required peripherals to communicate with onboard ADCs and DACs (3rd-party IPs or custom-made ones) as well as with an interchangeable fieldbus communication module, allowing the board to be integrated in various types of industrial control networks in view of future evolution. This new architecture is presented together with the advantages in terms of modularity and reusability for future projects.

European Organization for Nuclear Research (CERN), Geneva, Switzerland

During Long Shutdown 2 (LS2) at CERN, the SPS Beam Dumping System (SBDS) was completely renovated and relocated to SPS Point 5. This allowed to deploy at the SPS the Beam Energy Tracking System (BETS) and the Trigger Synchronization Unit (TSU), initially designed for and operational at the LHC Beam Dumping System (LBDS). The challenge encountered in this migration was the dynamic multi-cycle operation scheme with fast ramping cycles of the SPS in comparison to the long physics periods at stable energy of the LHC. This paper describes the modification of both BETS and TSU systems as well as the automatic arming sequence put in place, including the interactions with the SPS injection, the beam revolution frequency, and the Beam Interlock System (BIS).

In agreement with the IEC 61511 functional safety standard, fail-safe application programs should be written using a Limited Variability Language (LVL), that has a limited number of operations and data types, such as LD (Ladder Diagrams) or FBD (Function Block Diagrams) for safety PLC (Programmable Logic Controller) languages. The specification of safety instrumented systems, as part of the Safety Requirements Specification document, shall unambiguously define the logic of the program, creating a one-to-one relationship between code and specification. Hence, coding becomes a translation from a specification language to PLC code. This process is repetitive and error-prone when performed by a human. In this paper we describe the process of fully generating Siemens TIA portal LD programs for safety applications from a formal specification. The process starts by generating an intermediate model that represents a generic LD program based on a predefined meta-model. This intermediate model is then automatically translated into code. The idea can be expanded to other equivalent LVL languages from other PLC manufacturers. In addition, the intermediate model can be generated from different specification formalisms having the same level of expressiveness as the one presented in this paper: a Cause-Effect Matrix. Our medium-term vision is to automatically generate fail-safe programs from diverse formal specification methods and using different LVLs.

In recent years, beam diagnostics systems with increasingly large numbers of monitors, and systems handling vast amounts of data have been deployed at CERN. Their regular operation and maintenance poses a significant challenge. These systems have to run 24/7 when the accelerators are operating and the quality of the data they produce has to be guaranteed. This paper presents our experience developing applications in Python which are used to assure the readiness and availability of these large systems. The paper will first give a brief introduction to the different functionalities required, before presenting the chosen architectural design. Although the applications work mostly with online data, logged data is also used in some cases. For the implementation, standard Python libraries (e.g. PyQt, pandas, NumPy) have been used, and given the demanding performance requirements of these applications, several optimisations have had to be introduced. Feedback from users, collected during the first year’s run after CERN’s Long Shutdown period and the 2023 LHC commissioning, will also be presented. Finally, several ideas for future work will be described.

Cooling and air conditioning systems play a vital role for the operation of the accelerators and experimental complex of the European Organization for Nuclear Research (CERN). Without them, critical accelerator machinery would not operate reliably as many machines require a fine controlled thermodynamic environment. These operation conditions come with a significant energy consumption: about 12% (75 GWh) of electricity consumed by the Large Hadron Collider (LHC) during a regular run period is devoted to cooling and air conditioning. To align with global CERN objectives of minimizing its impact on the environment, the Cooling and Ventilation (CV) group, within the Engineering Department (EN), has been developing several initiatives focused on energy savings. A particular effort is led by the automation and controls section which has been looking at how controls and automation strategies can be optimized without requiring costly hardware changes. This paper addresses several projects of this nature, by presenting their methodology and results achieved to date. Some of them are particularly promising as real measurements revealed that electricity consumption was more than halved after implementation. Due to the pertinence of this effort in the current context of energy crisis, the paper also draws a careful reflection on how it is planned to be further pursued to provide more energy-efficient cooling and ventilation services at CERN.

Changing the operating system (OS) for large heterogeneous infrastructures in the research domain is complex. It requires great effort to prepare, migrate and validate the common generic components, followed by the specific corner cases. The trigger to change OS mainly comes from Industry and is based on multiple factors, such as OS end-of-life and the associated lack of security updates, as well as hardware end-of-life and incompatibilities between new hardware and old OS. At the time of writing, the CERN Accelerator Controls computing infrastructure consists of ~4000 heterogeneous systems (servers, consoles and front-ends) running CentOS 7. The effort to move to CentOS 7 was launched in 2014 and deployed operationally 2 years later. In 2022, a project was launched to select and prepare the next Linux OS for Controls servers and consoles. This paper describes the strategy behind the OS choice, and the challenges to be overcome in order to switch to it within the next 2 years, whilst respecting the operational accelerator schedule and factoring in the global hardware procurement delays. Details will be provided on the technical solutions implemented by the System Administration team to facilitate this process. In parallel, whilst embarking on moving away from running Controls services on dedicated bare metal platforms towards containerization and orchestration, an open question is whether the OS of choice, RHEL9, is the most suitable for the near future and if not what are the alternatives?

The software engineering of process control system for CERN cryogenic installations is based on an automatic code production methodology and continuous integration practice. This solution was initially developed for the LHC Accelerator applications, then adapted to LHC Detectors, test facilities and non-LHC cryogenic facilities. Over the years, this approach allowed the successful implementation of many control system upgrades, as well as the development of new applications while improving quality assurance and minimizing manpower resources. The overall complexity of automatic software production chains, their challenging maintenance, deviation between software production methods for different cryogenic domains and frequent evolution of CERN frameworks led to the system’s complete review. A new unified software production system was designed for all cryogenic domains and industrial technologies used. All previously employed frameworks, tools, libraries, code templates were classified, homogenized and implemented as common submodules, while projects specific configuration were grouped in custom application files. This publication presents the new unified software production solution, benefits from shared methodology between different cryogenics domains, as well as a summary of two years of experience with several cryogenic applications from different PLCs technologies.

The ALICE experiment at the LHC has already been in operation for 15 years, and during its life several detectors have been replaced, new instruments installed, and some technologies changed. The control system has therefore also had to adapt, evolve and expand, sometimes departing from the symmetry and compactness of the original design. In a large collaboration, different groups contribute to the development of the control system of their detector. For the central coordination it is important to maintain the overview of the integrated control system to assure its coherence. Tools to visualize the structure and other critical aspects of the system can be of great help and can highlight problems or features of the control system such as deviations from the agreed architecture. This paper will present that existing tools, such as graphical widgets available in the public domain, or techniques typical of scientific analysis, can be adapted and help assess the coherence of the development, revealing any weaknesses and highlighting the interdependence of parts of the system. We show how we have used some of these techniques to analyse the coherence of the ALICE control system, and how this contributed to pointing out criticalities and key points.

Towards a Flexible and Secure Python Package Repository Service

CERN, Meyrin, Switzerland

The use of 3rd-party and internal software packages has become a crucial part of modern software development. Not only does it enable faster development, but it also facilitates sharing of common components, which is often necessary for ensuring correctness and robustness of developed software. To enable this workflow, a package repository is needed to store internal packages and provide a proxy to 3rd-party repository services. This is particularly important for systems that operate in constrained networks, as is common for accelerator control systems. Despite its benefits, installing arbitrary software from a 3rd-party package repository can pose security and operational risks. Therefore, it is crucial to implement effective security measures, such as usage logging, package moderation and security scanning. However, experience at CERN has shown off-the-shelf tools for running a flexible repository service for Python packages not to be satisfactory. For instance, the dependency confusion attack first published in 2021 has still not been fully addressed by the main open-source repository services. An in-house development was conducted to address this, using a modular approach to building a Python package repository that enables the creation of a powerful and security-friendly repository service using small components. This paper describes the components that exist, demonstrates their capabilities within CERN and discusses future plans. The solution is not CERN-specific and is likely to be relevant to other institutes facing comparable challenges.

The CERN Accelerator Data Logging Service (NXCALS) stores data generated by the accelerator infrastructure and beam related devices. This amounts to 3.5TB of data per day, coming from more than 2.5 million signals from heterogeneous systems at various frequencies. Around 85% of this data is transmitted through the Controls Middleware (CMW) infrastructure. To reliably gather such volumes of data, the acquisition system must be highly available, resilient and robust. It also has to be highly efficient and easily scalable, given the regularly growing data rates and volumes, particularly for the increases expected to be produced by the future High Luminosity LHC. This paper describes the NXCALS time series acquisition software, known as Data Sources. System architecture, design choices, and recovery solutions for various failure scenarios (e.g. network disruptions or cluster split-brain problems) will be covered. Technical implementation details will be discussed, covering the clustering of Akka Actors collecting data from tens of thousands of CMW devices and sharing the lessons learned. The NXCALS system has been operational since 2018 and has demonstrated the capability to fulfil all aforementioned characteristics, while also ensuring self-healing capabilities and no data losses during redeployments. The engineering challenge, architecture, lessons learned, and the implementation of this acquisition system are not CERN-specific and are therefore relevant to other institutes facing comparable challenges.

Until recently, most of CERN’s beam visualisation systems have been based on increasingly obsolescent analogue cameras. Hence, there is an on-going campaign to replace old or install new digital equivalents. There are many challenges associated with providing a homogenised solution for the data acquisition of the various visualization systems in an accelerator complex as diverse as CERN’s. However, a generic real-time software in C++ has been developed and already installed in several locations to control such systems. This paper describes the software and the additional tools that have also been developed to exploit the acquisition systems, including a Graphical User Interface (GUI) in Java/Swing and web fixed displays. Furthermore, it analyses the specific challenges of each use-case and the chosen solutions that resolve issues including any subsequent performance limitations.

In the scope of the Swiss Light Source (SLS) upgrade project, SLS 2.0, at Paul Scherrer Institute (PSI) two New Processing Platforms (NPP), both running RT Linux, have been added to the portfolio of existing VxWorks and Linux VME systems. At the lower end we have picked a variety of boards, all based on the Xilinx Zynq UltraScale⁺ MPSoC. Even though these devices have less processing power, due to the built-in FPGA and Real-time CPU (RPU) they can deliver strict, hard RT performance. For high-throughput, soft-RT applications we went for Intel Xeon based single-board PCs in the CPCI-S form factor. All platforms are operated as diskless systems. For the Zynq systems we have decided on building in-house a Yocto Kirkstone Linux distribution, whereas for the Xeon PCs we employ off-the-shelf Debian 10 Buster. In addition to these new NPP systems, in the scope of our new EtherCAT-based Motion project, we have decided to use small x86₆4 servers, which will run the same Debian distribution as NPP. In this contribution we present the selected Operating Systems (OS) and discuss how we build, deploy and provision them to the diskless clients.

A Hardware and Software Toolbox is being created to accelerate the engineering of electronic components for large facility upgrades at the Paul Scherrer Institut. This Toolbox consists of modular hardware and Base Designs that follow the CPCI-S.0 concept. Our goal is to provide a starting foundation, tools, modules and libraries to simplify and accelerate developments. This contribution will focus on the Base Designs that provide advanced starting points for applications on MPSoC devices, AMD Zynq Ultrascale+. It is an environment containing both a ready-to-use system and functional building blocks. It features two main layers: one for the Processing System (PS) and one for the Programmable Logic (PL). The former is a collection of the software packages that run within an Operating System. The latter, lower layer consists of a seed Vivado project and an array of ready-to-use firmware modules. A set of device-tree-overlay scripts is also available to create high-level connections between PS and PL components.

PSI, Villigen PSI, Switzerland

Capturing both raw and metadata during an experiment is of the utmost importance, as it provides valuable context for the decisions made during the experiment and the acquisition strategy. However, logbooks often lack seamless integration with facility-specific services such as authentication and data acquisition systems and can prove to be a burden, particularly in high-pressure situations during experiments. To address these challenges, SciLog has been developed as a logbook system utilizing MongoDB, Loopback, and Angular. Its primary objective is to provide a flexible and extensible environment, as well as a user-friendly interface. SciLog relies on atomic entries in a NoSQL database that can be easily queried, sorted, and displayed according to the user’s requirements. The integration with facility-specific authorization systems and the automatic import of new experiment proposals enable a user experience that is specifically tailored for the challenging environment of experiments conducted at large research facilities. The system is currently in use during beam time at the Paul Scherrer Institut, where it is collecting valuable feedback from scientists to enhance its capabilities.

The Electromagnetic Calorimeter (ECAL) is a subdetector of the CMS experiment. Composed of a barrel and two endcaps, ECAL uses lead tungstate scintillating crystals to measure the energy of electrons and photons produced in high-energy collisions at the Large Hadron Collider (LHC). The LHC will undergo a major upgrade during the 2026-2029 period to build the High-Luminosity LHC (HL-LHC). The HL-LHC will allow for physics measurements with one order of magnitude larger luminosity during its Phase-2 operation. The higher luminosity implies a dramatic change of the environmental conditions for the detectors, which will also undergo a significant upgrade. The endcaps will be decommissioned and replaced with a new detector. The barrel will be upgraded with new front-end electronics. A Sniffer system will be installed to analyse the airflow from within the detector. New high voltage and water-cooled, radiation tolerant low voltage power supplies are under development. The ECAL barrel safety system will replace the existing one and the precision temperature monitoring system will be redesigned. From the controls point of view, the final barrel calorimeter will practically be a new detector. The large modification of the underlying hardware and software components will have a considerable impact in the architecture of the detector control system (DCS). In this document the upgrade plans and the preliminary design of the ECAL DCS to ensure reliable and efficient operation during the Phase-2 period are summarized.

Stream-based Virtual Device Simulation for Enhanced EPICS Integration and Automated Testing

1522

E9, London, United Kingdom

Integrating devices into the Experimental Physics and Industrial Control System (EPICS) can often take a suboptimal path due to discrepancies between available documentation and real device behaviour. To address this issue, we introduce "vd" (virtual device), a software for simulating stream-based virtual devices that enables testing communication without connecting to the real device. It is focused on the communication layer rather than the device’s underlying physics. The vd listens to a TCP port for client commands and employs ASCII-based byte stream communication. It offers easy configuration through a user-friendly config file containing all necessary information to simulate a device, including parameters for the simulated device and information exchanged via TCP, such as commands and queries related to each parameter. Defining the protocol for data exchange through a configuration file allows users to simulate various devices without modifying the simulator’s code. The vd’s architecture enables its use as a library for creating advanced simulations, making it a tool for testing and validating device communication and integration into EPICS. Furthermore, the vd can be integrated into CI pipelines, facilitating automated testing and validation of device communication, ultimately improving the quality of the produced control system.

The Power and Signal Distribution System (PaSD) is a key component of the SKA-Low telescope, responsible for control and monitoring of local power to the electronic components of the RF signal chain for the antennas, and collecting the RF signals for transmission to the Central Processing Facility. The system comprises "SMART boxes" (SMART: Small Modular Aggregation and RFoF Trunk) which each connect directly to around 10 antennas to provide local monitoring and control, and one Field Node Distribution Hub (FNDH) per station which distributes power to all the SMART boxes and provides a communications gateway as well as additional local monitoring. All communication to the SMART boxes is funnelled through the FNDH on a multi-drop serial bus using the Modbus ASCII protocol. This paper will describe how the PaSD will be integrated into the Tango-based SKA-Low Monitoring Control and Calibration Subsystem (MCCS) software, including the facility for a drop-in Python simulator which can be used to test the software.

Diamond Light Source has chosen the MicroTCA platform for high performance data acquisition and controls as part of the Diamond-II 4th generation light source upgrade. One requirement is the ability to create custom advanced mezzanine cards (AMCs) for signal conditioning and interlock support. To facilitate this, a module management controller (MMC) is required to negotiate payload power and communications between the AMC and MicroTCA shelf. A popular open-source firmware for controlling such a device is OpenMMC, a project from the Brazillian Light Source (LNLS), which employs a modular approach using FreeRTOS on ARM microcontrollers. Initially, OpenMMC supported the NXP LPC series of devices. However, to make use of Diamond’s existing ST Microelectronics (STM32) infrastructure, we have integrated a CERN fork of the project supporting STM32 microcontrollers into OpenMMC. In this paper, we outline our workflow and experiences introducing a new ARM device into the project.

The Square Kilometre Array Observatory (SKAO) project is an international effort to build two radio interferometers in South Africa and Australia to form one Observatory monitored and controlled from the global headquarters in the United Kingdom at Jodrell Bank. The Monitoring, Control and Calibration System (MCCS) is the "front-end" management software for the Low telescope which provides monitoring and control capabilities as well as implementing calibration processes and providing complex diagnostics support. Once completed the Low telescope will boast over 130, 000 individual log-periodic antennas and so the scale of the data generated will be huge. It is estimated that an average of 8 terabits per second of data will be transferred from the SKAO telescopes in both countries to Central Processing Facilities (CPFs) located at the telescope sites. In order to keep pace with this magnitude of data production an equally impressive data acquisition (DAQ) system is required. This paper outlines the challenges encountered and solutions adopted whilst incorporating a bespoke DAQ library within the SKAO’s Kubernetes-Tango ecosystem in the MCCS subsystem in order to allow high speed data capture whilst maintaining a consistent deployment experience.

The Argonne Tandem Linear Accelerating System (ATLAS) facility at Argonne National Laboratory is researching ways at avoiding a crisis caused by the end-of-life issues with its 30 year-old CAMAC system. Replacement parts for CAMAC have long since been unavailable causing the potential for long periods of accelerator down times once the limited CAMAC spares are exhausted. ATLAS has recently upgraded the Ethernet in the facility from a 100-Mbps (max) to a 1-Gbps network. Therefore, an Ethernet-based data acquisition system is desirable. The data acquisition replacement requires reliability, speed, and longevity to be a viable upgrade to the facility. In addition, the transition from CAMAC to a modern data acquisition system will be done with minimal interruption of operations.

Funding: This work was supported by the U.S. Department of Energy, under Contract No. DE-AC02-06CH11357. This research used resources of ANLs ATLAS facility, which is a DOE Office of Science User Facility.
The Argonne Tandem Linac Accelerator System (ATLAS) has been a National User Facility since 1985. In that time, many of the systems that help operators retrieve, modify, and store beamline parameters have not kept pace with the advancement of technology. Development of a new method of storing and retrieving beamline parameters resulted in the testing and installation of a time-series database as a potential replacement for the traditional relational database. InfluxDB was selected due to its self-hosted Open-Source version availability as well as the simplicity of installation and setup. A program was written to periodically gather all accelerator parameters in the control system and store them in the time-series database. This resulted in over 13,000 distinct data points, captured at 5-minute intervals. A second test captured 35 channels on a 1-minute cadence. Graphing of the captured data is being done on Grafana, an Open-Source version is available that co-exists well with InfluxDB as the back-end. Grafana made visualizing the data simple and flexible. The testing has allowed for the use of modern graphing tools to generate new insights into operating the accelerator, as well as opened the door to building large data sets suitable for Artificial Intelligence and Machine Learning applications.

The Los Alamos Neutron Science Center (LANSCE) operates at a maximum repetition rate of 120 Hz. Timing gates are required for synchronization of the accelerator to provide beam acceleration along the LINAC and beam distribution to the five experimental areas. They are also provided to other devices with sensitive operating points relative to the machine cycle. Over the last 50 years of operations many new time sensitive pieces of equipment have been added. This has changed the demand on, and complexity of, the timing system. Further driven by equipment obsolescence issues, the timing system un-derwent many upgrades and revitalization efforts, with the most significant deployment starting in 2016. Due to these upgrade efforts, the timing system architecture design changed from a purely centralized system, to a distributed event-based one. The purpose of this paper is to detail the current state of the timing system, as a hy-brid system with the gate events being generated from a new timing master system, while still utilizing legacy distribution and fanout systems. Upgrades to the distribu-tion system are planned, but due to the required beam delivery schedule, they can only be deployed in sections during four-month annual maintenance cycles. The paper will also cover the off-the-shelf solutions that have been found for standardization, and the efforts towards a life cycle management process.

The LCLS-II Project at SLAC National Accelerator is a major upgrade to the lab’s Free Electron Laser (FEL) facility adding a new injector and superconducting linac. In order to support this new linac, a vacuum pumping scheme was needed to isolate the liquid helium lines cooling the RF cavities inside the cryomodules from outside ambient heat as well as to exhaust any leaking helium gas. Carts were built with support for both roughing and high vacuum pumps and read back diagnostics. Additionally, a Programmable Logic Controller (PLC) was then configured to automate the pump down sequence and provide interlocks in the case of a vacuum burst. The design was made modular such that it can be manually relocated easily to other sections of the linac if needed depending on vacuum conditions.

The Super Conducting (SC) Linac Coherent Light Source II (LCLS-II) facility at SLAC is capable of delivering an electron beam at a fast rate of up to 1MHz. The high-rate necessitates the processing algorithms and data exchanges with other high-rate systems to be implemented with FPGA technology. For LCLS-II, SLAC has deployed a common platform solution (hardware, firmware, software) which is used by timing, machine protection and diagnostics systems. The wire scanner diagnostic system uses this solution to acquire beam synchronous time-stamped readings, of wire scanner position and beam loss during the scan, for each individual bunch. This paper explores the software architecture and control system integration for LCLS-II wire scanners using the common platform solution.

The LCLS-II Project at SLAC National Accelerator Laboratory has constructed a new superconducting accelerator which occupies the first kilometer of SLAC’s original 2-mile-long linear accelerator tunnel. The LCLS-II Vacuum System consists of a combination of particle free(PF) and non-particle free vacuum(non-PF) areas and multiple independent and interdependent systems, including the beamline vacuum, RF system vacuum, cryogenic system vacuum and support systems vacuum. The Vacuum Control System incorporates controls and monitoring of a variety of gauges, pumps, valves and Hiden RGAs. The design uses a Programmable Logic Controller (PLC) to perform valve interlocking functions to isolate bad vacuum areas. In PF areas, a voting scheme has been implemented for slow and fast shutter interlock logic to prevent spurious trips. Additional auxiliary control functions and high-level monitoring of vacuum components is reported to global control system via an Experimental Physics and Industrial Control System (EPICS) input output controller (IOC). This paper will discuss the design as well as the phased approach to installation and successful checkout of LCLS-II Vacuum Control System.

ALPS II is a light-shining through a wall (LSW) experiment to search for WISPs (very Weakly Interacting Slim Particles). Potential WISP candidates are axion-like particles or hidden sector photons. Axion-like particles may convert to light (and vice versa) in presence of a magnetic field. Similarly, hidden sector photons "mix" with light independent of any magnetic fields. This is exploited by ALPS II- Light from strong laser is shone into a magnetic field. Laser photons can be converted into a WISPs in front of a light-blocking barrier and reconverted into photons behind that barrier. The experiment exploits optical resonators for laser power build-up in a large-scale optical cavity to boost the available power for the WISP production as well as their reconversion probability to light. The Distributed Object-Oriented Control System - DOOCS - provides a versatile software framework for creating accelerator-based control system applications. These can range from monitoring simple temperature sensors up to high-level controls and feedbacks of beam parameters as required for complex accelerator operations. In order to enable data analysis by researchers who do not have access to the DOOCS internal control system to read measured values, the measurement and control data are extracted from the control system and saved in HDF5 file format. Through this process, the data is decoupled from the control system and can be analysed on the NAF computer system, among other things. NodeRed acts here as a graphical tool for creating HDF5 files.

CEA Saclay Irfu is in charge of the major part of the control system of the SARAF-LINAC accelerator based at Soreq in Israel. This scope also includes the Machine Protection System. This system prevents any damage in the accelerator by shutting down the beam in case of detection of risky incidents like interceptive diagnostics in the beam or vacuum or cooling defects. So far, the system has been used successfully up to the MEBT. It will be tested soon for the super conducting Linac consisting of 4 cryomodules and 27 cavities. This Machine Protection System relies on three sets: the MRF timing system that is the messenger of the "shut beam" messages coming from any devices, IOxOS MTCA boards with custom FPGA developments that monitor the Section Beam Current Transmission along the accelerator and a Beam Destination Master that manages the beam destination required. This Destination Master is based on a master PLC. It permanently monitors Siemens PLCs that are in charge of the "slow" detection for fields such as vacuum, cryogenic and cooling system. The paper describes the architecture of this protection system and the exchanges between these three main parts.

The old power supply control system of SFC (Sector Focused Cyclotron) has been in operation for more than a decade. Control system architecture is centralized, and equipment failure rate is getting higher and higher. The new control system uses the EPICS architecture, and the hardware uses Advantech’s APAX modules. The IOC runs on the APAX host and interacts with the module through API functions. The system has been running very stable for several months without failure.

MATLAB is essential for accelerator scientists engaged in data analysis and processing across diverse fields, including particle physics experiments, synchrotron light sources, XFELs, and telescopes, due to its extensive range of built-in functions and tools. Scientists also depend on EPICS 7* to control and monitor complex systems. Since Python has gained popularity in the scientific community and many facilities have been migrating towards it, SLAC has developed matpva, a Python interface to integrate EPICS 7 with MATLAB. Matpva utilizes the Python P4P module** and EPICS 7 to offer a robust and reliable interface for MATLAB users that employ EPICS 7. The EPICS 7 PVAccess API allows higher-level scientific applications to get/set/monitor simple and complex structures from an EPICS 7-based control system. Moreover, matpva simplifies the process by handling the data type conversion from Python to MATLAB, making it easier for researchers to focus on their analyses and innovative ideas instead of technical data conversion. By leveraging matpva, researchers can work more efficiently and make discoveries in diverse fields, including particle physics and astronomy.

PSI, Villigen PSI, Switzerland

CamServer is a Python package for data stream processing developed at Paul Scherrer Institute (PSI). It is a key component of SwissFEL’s data acquisition, where it is deployed on a cluster of servers and used for displaying and processing images from all cameras. It scales linearly with the number of servers and is capable of handling multiple high-resolution cameras at 100Hz, as well as a variety of data types and sources. The processing unit, called a pipeline, runs in a private process that can be either permanent or spawned on demand. Pipelines consume and produce ZMQ streams, but input data can be arbitrary using an adapter layer (e.g. EPICS). A proxy server handles requests and creates pipelines on the cluster’s worker nodes according to rules. Some processing scripts are available out of the box (e.g. calculation of standard beam metrics) but users can upload custom ones. The system is managed via its REST API, using a client library or a GUI application. CamServer’s output data streams are consumed by a variety of client types such as data storage, image visualization, monitoring and DAQ applications. This work describes the use of CamServer, the status of the SwissFEL’s cluster and the development roadmap with plans for SLS 2.0.

During its construction and production life cycles, the Square Kilometre Array Observatory (SKAO) will generate non-scientific, i.e. engineering, data. The sources of the engineering data are either hardware devices or software programs that generate this data. Thanks to the Tango Controls software framework, the engineering data can be automatically stored in a relational database, which SKAP refers to as the Engineering Data Archive (EDA). Making the data in the EDA accessible and available to engineers and users in the observatory is as important as storing the data itself. Possible use cases for the data are verification of systems under test, performance evaluation of systems under test, predictive maintenance and general performance monitoring over time. Therefore we tried to build on the knowledge that other research facilities in the Tango Controls collaboration already gained, when they designed, implemented, deployed and ran their engineering data archives. SKAO implemented a prototype for its EDA, that leverages several open-source software packages, with Tango Controls’ HDB++, the Timescaledb time series database and Kubernetes at its core. In this overview we will answer the immediate question "But why do we not just do, what others are doing?" and explain the reasoning behind our choices in the design and in the implementation.

HZB, Berlin, Germany

Digital twins, i.e. theory and design tools connected to the real devices and machine by mapping of physics components to the technical correspondents, are powerful tools providing accelerators with commissioning predictions and feedback capabilities. This paper describes a new tool allowing for greater flexibility in configuring the modelling part combined with ease of adding new features. To enable the various components developed in EPICS, Python, C, and C++ to work together seamlessly, we adopt a microservice architecture, with REST API services providing the interfaces between the components. End user scripts are implemented as REST API services, allowing for better data analysis and visualization. Finally, the paper describes the integration of dash and ploty for enhanced data comparison and visualization. Overall, this workflow provides a powerful and flexible solution for managing and optimizing BESSY II digital twins, with the potential for further customization and extension to upcoming machines.

Fermilab, Batavia, Illinois, USA

PIP-II is an 800 MeV superconducting RF linac under development at Fermilab. As the new first stage in our accelerator chain, it will deliver high-power beam to multiple experiments simultaneously and thus drive Fermilab’s particle physics program for years to come. In a pivot for Fermilab, controls for PIP-II are based on EPICS instead of ACNET, the legacy control system for accelerators at the lab. This paper discusses the status of the EPICS controls work for PIP-II. We describe the EPICS tools selected for our system and the experience of operators new to EPICS. We introduce our continuous integration / continuous development environment. We also describe some efforts at cooperation between EPICS and ACNET, or efforts to move towards a unified interface that can apply to both control systems.

The SKA Project is a science mega-project whose mission is to build the world’s two largest radio telescopes with sensitivity, angular resolution, and survey speed far surpassing current state-of-the-art instruments at relevant radio frequencies. The Low Frequency telescope, SKA-Low, is designed to observe between 50 and 350 MHz and will be built at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory in Western Australia. The Mid Frequency telescope, SKA-Mid, is designed to observe between 350 MHz and 15 GHz and will be built in the Meerkat National Park, in the Northern Cape of South Africa. Each telescope will be delivered in a number of stages, called Array Assemblies. Each Array Assembly will be a fully working telescope which will allow us to understand the design and potentially improve the system to deliver a better scientific instrument for the users. The final control system will consist of around 2 million control points per telescope, and the first Array Assembly, known as AA0.5, is being delivered at the time of ICALEPCS 2023.

Operation of the Swiss Light Source (SLS) at the Paul Scherrer Institue (PSI) in Switzerland began in 2000 and it quickly became one of the most successful synchrotron radiation facilities worldwide, providing academic and industry users with a suite of excellent beamlines covering a wide range of methods and applications. To maintain the SLS at the forefront of synchrotron user facilities and to exploit all of the improvement opportunities, PSI prepared a major upgrade project for SLS, named SLS 2.0. The Controls and Science IT (CaSIT) subproject was established to help instigate a project management structure to facilitate new concepts, increased communication, and clarify budgetary responsibility. This article focusses on the progress being made to exploit the current technological opportunities offered by a break in operations whilst taking into consideration future growth opportunities and realistic operational support within an academic research facility.

The successful use of machine learning (ML) in particle accelerators has greatly expanded in recent years; however, the realities of operations often mean very limited machine availability for ML development, impeding its progress in many cases. This paper presents a framework for exploiting physics-based simulations, coupled with real machine data structure, to facilitate the investigation and implementation of reinforcement learning (RL) algorithms, using the longitudinal bunch-merge process in the Booster and Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory (BNL) as examples. Here, an initial fake wall current monitor (WCM) signal is fed through a noisy physics-based model simulating the behavior of bunches in the accelerator under given RF parameters and external perturbations between WCM samples; the resulting output becomes the input for the RL algorithm and subsequent pass through the simulated ring, whose RF parameters have been modified by the RL algorithm. This process continues until an optimal policy for the RF bunch merge gymnastics has been learned for injecting bunches with the required intensity and emittance into the Relativistic Heavy Ion Collider (RHIC), according to the physics model. Robustness of the RL algorithm can be evaluated by introducing other drifts and noisy scenarios before the algorithm is deployed and final optimization occurs in the field.

The Central Signal Processor Local Monitor and Control (CSP. LMC) is a software component that allows the flow of information and commands between the Telescope Manager (TM) and the subsystems dedicated to signal processing, namely the correlator and beamformer, the pulsar search and the pulsar timing engines. It acts as an adapter by specialising the commands and associated data from the TM to the subsystems and by exposing the subsystems as a unified entity while monitoring their status. In this paper, we approach the problem of creating a User Interface (UI) for such a component. Through a series of short learning cycles, we want to explore different ways of looking at the system and build an initial set of UIs that can be refined to be used as engineering UIs in the first Array Assembly of the Square Kilometre Array. The process heavily involves some of the developers of the CSP. LMC in creating the dashboards, and other ones as participants in informal evaluations. In fact, the opportunities offered by Taranta, a tool to develop web UIs without needing web-development skills, make it possible to quickly realise a working dashboard that can be promptly tested. This also supports the short feedback cycle advocated by a Lean UX approach and maps well in a bi-weekly sprint cadence. In this paper, we will describe the method and present the results highlighting strengths and pain points where faced.

Taranta, developed jointly by MAX IV Laboratory and SKA Observatory, is a web based no-code interface for remote control of instruments at accelerators and other scientific facilities. It has seen a great success in system development and scientific experiment usage. In the past two years, the panel of users has greatly expanded. The first generation of Taranta was not able to handle the challenges introduced by the user cases, notably the decreased performance when a high number of data points are requested, as well as new functionality requests. Therefore, a series of refactoring and performance improvements of Taranta are ongoing, to prepare it for handling large data transmission between Taranta and multiple sources of information, and to provide more possibilities for users to develop their own dashboards. This article presents the status of the Taranta project from the aspects of widgets updates, packages management, optimization of the communication with the backend TangoGQL, as well as the investigation on a new python library compatible with the newest python version for TangoGQL. In addition to the technical improvements, more facilities other than MAX IV and SKAO are considering to join Taranta project. One workshop has been successfully held and there will be more in the future. This article also presents the lesson learned from this project, the road map, and the GUI strategy for the near future.

Numerous standalone web applications have been developed over the last 10 years to support the configuration and operation of the CERN accelerator complex. These applications have different levels of complexity, but they all support hundreds of users for essential activities. A monolithic architecture has been utilised so far, tailoring the standalone applications to specific accelerator needs. The global GUI technology landscape continues to evolve quickly, with most GUI technologies typically reaching end-of-life within 1-to-5 years. Keeping up-to-date with technologies presents a major challenge for the GUI application maintainers, with larger monolithic applications requiring long migration cycles which impede the introduction of new functionalities during the migration phase. To tackle the above issues within the CERN Controls domain, a new Micro Frontend architecture has been introduced and is being used to gradually migrate a large and complex AngularJS-based web application to Angular. This paper introduces the new generic architecture, which is not tied to any specific web framework. The development workflow, challenges, and lessons learned so far will be covered. The differences of this approach, particularly when compared to monolithic application technology migrations, will also be discussed.

The KEK injector linac provides e⁻/e⁺ beam to four independent storage rings and a positron damping ring. An accurate information management system of the accelerator components is very important since it is utilized for the beam tuning model. Especially, the incorrect magnet database may cause large deterioration in the quality of beam emittance. In KEK linac, a text-based database system has been used for the information management of magnet system in the long time. It comprises several independent text files which are master information to generate the EPICS database files and the other configuration files required for many linac control software. In this management scheme, it is not easy to access and update any information for the common user except control software expert. For this reason, a new web application-based magnet information management system was developed with the Angular and PHP framework. In the new system, the magnet information can be easily extracted and modified through any web browser for any user. In this paper, we report the new magnet information management system in detail.
