	D. Lacoste, R. Bourtembourg ESRF, Grenoble, France J. Forsberg MAX IV Laboratory, Lund University, Lund, Sweden T. Juerges SKAO, Macclesfield, United Kingdom J.J.D. Mol ASTRON, Dwingeloo, The Netherlands L. Pivetta, G. Scalamera Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy S. Rubio-Manrique ALBA-CELLS, Cerdanyola del Vallès, Spain
	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.

THMBCMO02	Enhancing Data Management with SciCat: A Comprehensive Overview of a Metadata Catalogue for Research Infrastructures	1195
	C. Minotti, A. Ashton, S.E. Bliven, S. Egli PSI, Villigen PSI, Switzerland F.B. Bolmsten, M. Novelli, T.S. Richter ESS, Copenhagen, Denmark M. Leorato MAX IV Laboratory, Lund University, Lund, Sweden D. McReynolds LBNL, Berkeley, California, USA L.A. Shemilt RFI, Didcot, United Kingdom
	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.

THMBCMO07	Reflective Servers: Seamless Offloading of Resource Intensive Data Delivery	1201
	S.L. Clark, T. D’Ottavio, M. Harvey, J.P. Jamilkowski, J. Morris, S. Nemesure BNL, Upton, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. 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.

THMBCMO09	DAQ System Based on Sardana and PandABox for Combined SAXS, Fluorescence and UV-Vis Spectroscopy Techniques at MAX IV CoSAXS Beamline
	V. Da Silva, R. Appio, M. Eguiraun, F. Herranz-Trillo, A.F. Joubert, M. Leorato, Y.L. Li, M. Lindberg, C. Takahashi, A.E. Terry MAX IV Laboratory, Lund University, Lund, Sweden C. Dicko Lund Institute of Technology (LTH), Lund University, Lund, Sweden W.T. Kitka S2Innovation, Kraków, Poland
	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. This paper presents the data acquisition (DAQ) strategy for combined SAXS, Ultraviolet-visible (UV-Vis) and Fluorescence Spectroscopy techniques. In general terms, the beamline control system is based on TANGO and on top of it, Sardana provides an advanced scan framework. Sardana performs the experiment orchestration, configuring and preparing the X-ray detector and the Spectrometers for UV-Vis and Fluorescence. Hardware triggers are used to synchronize the DAQ for the different techniques running simultaneously. The implementation is done using PandABox, which generates pulse trains for the X-ray detector and spectrometers. PandABox integration into the system is done with a Sardana Trigger Gate Controller, used to configure the pulse trains parameters as well to orchestrate the hardware triggers during a scan. This paper describes the individual techniques’ integration into the control system, the experiment orchestration and synchronization and the new experiment possibilities this multi-technique DAQ system brings to MAX IV beamlines.

THMBCMO10	SECoP Integration for the Ophyd Hardware Abstraction Layer	1212
	P. Wegmann, K. Kiefer, O. Mannix, L. Rossa, W. Smith HZB, Berlin, Germany E. Faulhaber MLZ, Garching, Germany M. Zolliker PSI, Villigen PSI, Switzerland
	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. Klaus Kiefer et al.

THMBCMO11	Full Stack PLC to EPICS Integration at ESS	1216
	A. Rizzo, E.E. Foy, D. Hasselgren, A.Z. Horváth, A. Petrushenko, J.A. Quintanilla, S.C.F. Rose, A. Simelio ESS, Lund, Sweden
	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. https://www.siemens.com/global/en/products/automation/systems/industrial/plc.html https://www.beckhoff.com/en-en/products/i-o/ethercat/ * https://epics-controls.org/

THMBCMO13	TwinCAT BSD Virtual Machines and Ansible Provisioning
	K.R. Lauer SLAC, Menlo Park, California, USA
	Funding: This work is supported by Department of Energy contract DE-AC02-76SF00515. TwinCAT/BSD is a lightweight FreeBSD-based operating system for TwinCAT PLCs that Beckhoff has offered since 2021 as an alternative to Microsoft Windows. These BSD-based PLCs offer the same runtime capabilities as their Windows-based counterparts and also bring the benefits of a Unix-like operating system. With TwinCAT/BSD images provided by Beckhoff, virtual machines are now easy to spin up for prototyping, development, and unit testing without direct access to PLC hardware. Ansible playbooks with some custom additions make provisioning these VMs and real PLCs simple. Automated installation of TwinCAT tools and packages, upgrades of runtime versions, route management, AMS Net ID settings, firewall configuration, and more are now handled with ease when using TwinCAT/BSD with Ansible.

THMBCMO14	Development of the SKA Control System, Progress, and Challenges	1221
	S. Vrcic, T. Juerges SKAO, Macclesfield, United Kingdom
	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.

THMBCMO15	Conan for Building C++ Tango Devices at SOLEIL	1227
	P. Madela, G. Abeillé, Y.-M. Abiven, X. Elattaoui, J. Pham, F. Potier SOLEIL, Gif-sur-Yvette, France
	At SOLEIL, our Tango devices are mainly developed in C++, with around 450 projects for building libraries and device servers for our accelerators and beamlines. We have a software factory that has enabled us to achieve continuous integration of our developments using Maven, which manages project dependencies. However, Maven is uncommon for C++. In addition, it has limitations that hinder us from supporting future platforms and new programming standards, leading us to replace it with Conan. Conan is a dependency and package manager for C and C++ that works on all platforms and integrates with various build systems. Its features are designed to enable modern continuous integration workflows with C++ and are an ideal alternative to Maven for our C++ build system. This transition is essential for the upgrade of SOLEIL (SOLEIL II), as we continue to develop new devices and update existing systems. We are confident that Conan will improve our development process and benefit our users. This paper will provide an overview of the integration process and describe the progress of deploying the new build system. We will share our insights and lessons learned throughout the transition process. SOLEIL II: Towards A Major Transformation of the Facility. Conan - C and C++ Open-Source Package Manager

THMBCMO17	FAIR Data of Physical and Digital Beamlines	1231
	G. Günther, O. Mannix, O. Ruslan, S. Vadilonga 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. * https://www.helmholtz-berlin.de/forschung/oe/wi/optik-strahlrohre/projekte/aquarius_en.html https://doi.org/10.1063/1.5084665 * https://pypi.org/project/raypyng

THMBCMO18	Advancements in Beamline Digital Twin at BESSYII	1236
	S. Vadilonga, G. Günther, S. Kazarski, R. Ovsyannikov, S.S. Sachse, W. Smith HZB, Berlin, Germany
	This presentation reports on the status of beamline digital twins at BESSY II. To provide a comprehensive beamline simulation experience we have leveraged BESSY II’s x-ray tracing program, RAY-UI[], widely used for beamline design and commissioning and best adapted to the requirements of our soft X-ray source BESSY II. We created a Python API, RayPyNG, capable to convert our library of beamline configuration files produced by RAY-UI into Python objects[]. This allows to embed beamline simulation into Bluesky[], our experimental controls software ecosystem. All optical elements are mapped directly into the Bluesky device abstraction (Ophyd). Thus beamline operators can run simulations and operate real systems by a common interface, allowing to directly compare theory predictions with real-time results[*]. We will discuss the relevance of this digital twin for process tuning in terms of enhanced beamline performance and streamlined operations. We will shortly discuss alternatives to RAY-UI like other software packages and ML/AI surrogate models.

THMBCMO21	Development of Standard MicroTCA Deployment at ESS	1238
	F. Chicken, J.J. Jamróz, J.P.S. Martins ESS, Lund, Sweden
	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.

THMBCMO22	Towards Defining a Synchronization Standard Between Beamline Components and Synchrotron Accelerators	1242
	J.A. Avila-Abellan, X. Serra-Gallifapresenter ALBA-CELLS, Cerdanyola del Vallès, Spain T.M. Cobb DLS, Oxfordshire, United Kingdom R. Hino ESRF, Grenoble, France O.H. Seeck DESY, Hamburg, Germany S. Zhang SOLEIL, Gif-sur-Yvette, France
	Funding: LEAPS-INNOV project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 101004728 Standardization is a magic word in the electronics engineering jargon. Under its umbrella, it is generated the utopia of transparent integration with the rest of the parts with minimal extra effort for the software integration. But the experimental setup in a synchrotron beamline presents multiple challenges: it is highly dynamic and diverse. In the frame of LEAPS-INNOV project (*), the Task 3 of Work Package 5 aims to define a standard for synchronization in the beamline sample environment. Their partners (ALBA, DESY, DLS, ESRF and SOLEIL) have already reached a common vision of synchronization requirements. This paper first details the participants’ actual synchronization needs on their facilities. Next, the requirements foreseen for the future are outlined in terms of interfaces, time constraints and compatibility with timing systems. To conclude, we summarize the current state of the project: the hardware interfaces and the hardware platform definition. They both have been decided considering long-term availability, use of standard sub-components, and keeping the compromise between cost, development time, maintenance, reliability, flexibility and performance. This hardware architecture proposal meets the identified requirements. In the future, under the scope of LEAPS-INNOV, a demonstrator will be built, and we will work with the industry for its future commercialization.

THMBCMO23	Development of a New Timing System for ISIS	1247
	R.A. Washington STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom
	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.

THMBCMO24	Time Synchronization and Timestamping for the ESS Neutron Instruments	1250
	N. Holmberg, T. Brys, T. Bögershausen, M. Olsson, J.E. Petersson, A. Pettersson, T.S. Richter, F. Rojas ESS, Lund, Sweden
	Funding: Tillväxtverket (Sweden) & European Union 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.

THMBCMO26	FRIB Beam Power Ramp Process Checker at Chopper Monitor	1256
	Z. Li, E. Bernal, J. Hartford, M. Ikegami FRIB, East Lansing, Michigan, USA
	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.

Department of Energy 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.

THMBCMO30	Using ArUco Codes for Beam Spot Analysis with a Camera at an Unknown Position	1264
	W. Smith, M. Arce, M. Bär, M. Gorgoi, C.E. Jimenez, I. Rudolph 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.

THMBCMO31	LImA2: Edge Distributed Acquisition and Processing Framework for High Performance 2D Detectors	1269
	S. Debionne, L. Claustre, P. Fajardo, A. Götz, A. Homs Puronpresenter, J. Kieffer, R. Ponsard ESRF, Grenoble, France
	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. * LIMA - https://accelconf.web.cern.ch/ICALEPCS2013/papers/frcoaab08.pdf Jungfraujoch - https://doi.org/10.1107/S1600577522010268 * pyFAI - https://doi.org/10.1107/S1600576715004306

THMBCMO32	Robotic Process Automation: on the Continuity of Applications Development at SOLEIL	1275
	L.E. Munoz, Y.-M. Abiven, M.-E. Couprie, A. Noureddine, J. Perez, A. Thureau, M. Valléau SOLEIL, Gif-sur-Yvette, France
	SOLEIL is currently in the Technical Design Report (TDR) phase of a major upgrade of the facility. In its digital transformation, the development of processes and systems with a high degree of autonomy is at the center of the SOLEIL II project. One of the important components used to achieve a high degree of autonomy is the use of 6-axis robotic arms. Thus, in recent years, SOLEIL has developed and put into operation robotic applications to automate some processes of its beamlines and some processes of magnetic measurements of the insertion devices. The last year SOLEIL has been developing two new robotic applications, having thus continuity in the development of applications using its robotic standard. This paper describes these two new applications that being developed to automate the injection of liquid samples for BioSAXS experiments at the SWING beamline and to automate the mechanical and magnetic adjustment of the modules that compose an insertion device.

THMBCMO34	Ultra-High Throughput Automated Macromolecular Crystallography Data Collection Using the Bluesky Framework	1280
	D.P. Perl, N. Frisina, D.E. Oram, N.P. Paterson 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.

THMBCMO35	Piezo Motor Based Hardware Triggered Nano Focus Caustic Acquisition	1285
	L.B.C. Campoi, G.S.R. Costa, N. Lopes Archilha, G.B.Z.L. Moreno, L.E.P. Vecina LNLS, Campinas, Brazil
	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.

THMBCMO36	Video Compression for areaDetector	1290
	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.

THMBCMO38	Jungfraujoch: Data Acquisition and Real-Time Image Analysis System for Kilohertz X-Ray Pixel Array Detector
	F. Leonarski, M. Brückner, C. Lopez-Cuenca, A. Mozzanica, H.C. Stadler Kleeb, M. Wang PSI, Villigen PSI, Switzerland
	Funding: F.L. acknowledges funding from the Open Research Data Program of the ETH Board and an innovation project supported by Innosuisse. The Swiss Light Source (SLS) will shortly start an upgrade to become a 4th generation light source. The higher brilliance of the new source brings new science opportunities - one of them is improving time resolution for X-ray crystallography to a microsecond regime. However, fully utilizing the new machine will require increasing the frame rate of pixel array detectors and, thus, data volume. Nine-megapixel JUNGFRAU detector* planned for SLS 2.0 beamlines will generate up to 36 GB/s raw data when operated at 2 kHz, which is very challenging for computing infrastructure. To operate this JUNGFRAU detector, PSI has developed a ’Jungfraujoch’ read-out system. The system can handle the complete data rate within a single server box for fast deployment at various beamlines. The system uses FPGA smart network interface cards for data acquisition, GPUs for on-the-fly image analysis (e.g., spot finding, radial integration), and high-end CPUs for image compression. In the presentation, I will show Jungfraujoch’s capabilities, experience from time-resolved macromolecular crystallography beamtimes, and technical details. I will highlight how FPGA design with high-level languages (C/C++) can help software developers design programmable logic quickly and how it can help in rapid verification. I will also present experiences working with a memory-coherent interconnect (OpenCAPI) to integrate FPGA boards into the server system and how it compares with a mainstream peripheral bus (PCI Express).

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.

Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy.
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.

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. This paper presents the data acquisition (DAQ) strategy for combined SAXS, Ultraviolet-visible (UV-Vis) and Fluorescence Spectroscopy techniques. In general terms, the beamline control system is based on TANGO and on top of it, Sardana provides an advanced scan framework. Sardana performs the experiment orchestration, configuring and preparing the X-ray detector and the Spectrometers for UV-Vis and Fluorescence. Hardware triggers are used to synchronize the DAQ for the different techniques running simultaneously. The implementation is done using PandABox, which generates pulse trains for the X-ray detector and spectrometers. PandABox integration into the system is done with a Sardana Trigger Gate Controller, used to configure the pulse trains parameters as well to orchestrate the hardware triggers during a scan. This paper describes the individual techniques’ integration into the control system, the experiment orchestration and synchronization and the new experiment possibilities this multi-technique DAQ system brings to MAX IV beamlines.

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.

Development of the SKA Control System, Progress, and Challenges

1221

S. Vrcic, T. Juerges
SKAO, Macclesfield, United Kingdom

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.

Conan for Building C++ Tango Devices at SOLEIL

1227

SOLEIL, Gif-sur-Yvette, France

At SOLEIL, our Tango devices are mainly developed in C++, with around 450 projects for building libraries and device servers for our accelerators and beamlines. We have a software factory that has enabled us to achieve continuous integration of our developments using Maven, which manages project dependencies. However, Maven is uncommon for C++. In addition, it has limitations that hinder us from supporting future platforms and new programming standards, leading us to replace it with Conan. Conan is a dependency and package manager for C and C++ that works on all platforms and integrates with various build systems. Its features are designed to enable modern continuous integration workflows with C++ and are an ideal alternative to Maven for our C++ build system. This transition is essential for the upgrade of SOLEIL (SOLEIL II*), as we continue to develop new devices and update existing systems. We are confident that Conan will improve our development process and benefit our users. This paper will provide an overview of the integration process and describe the progress of deploying the new build system. We will share our insights and lessons learned throughout the transition process.

FAIR Data of Physical and Digital Beamlines

1231

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.

Advancements in Beamline Digital Twin at BESSYII

1236

HZB, Berlin, Germany

This presentation reports on the status of beamline digital twins at BESSY II. To provide a comprehensive beamline simulation experience we have leveraged BESSY II’s x-ray tracing program, RAY-UI[*], widely used for beamline design and commissioning and best adapted to the requirements of our soft X-ray source BESSY II. We created a Python API, RayPyNG, capable to convert our library of beamline configuration files produced by RAY-UI into Python objects[**]. This allows to embed beamline simulation into Bluesky[***], our experimental controls software ecosystem. All optical elements are mapped directly into the Bluesky device abstraction (Ophyd). Thus beamline operators can run simulations and operate real systems by a common interface, allowing to directly compare theory predictions with real-time results[****]. We will discuss the relevance of this digital twin for process tuning in terms of enhanced beamline performance and streamlined operations. We will shortly discuss alternatives to RAY-UI like other software packages and ML/AI surrogate models.

ESS, Lund, Sweden

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.

Standardization is a magic word in the electronics engineering jargon. Under its umbrella, it is generated the utopia of transparent integration with the rest of the parts with minimal extra effort for the software integration. But the experimental setup in a synchrotron beamline presents multiple challenges: it is highly dynamic and diverse. In the frame of LEAPS-INNOV project (*), the Task 3 of Work Package 5 aims to define a standard for synchronization in the beamline sample environment. Their partners (ALBA, DESY, DLS, ESRF and SOLEIL) have already reached a common vision of synchronization requirements. This paper first details the participants’ actual synchronization needs on their facilities. Next, the requirements foreseen for the future are outlined in terms of interfaces, time constraints and compatibility with timing systems. To conclude, we summarize the current state of the project: the hardware interfaces and the hardware platform definition. They both have been decided considering long-term availability, use of standard sub-components, and keeping the compromise between cost, development time, maintenance, reliability, flexibility and performance. This hardware architecture proposal meets the identified requirements. In the future, under the scope of LEAPS-INNOV, a demonstrator will be built, and we will work with the industry for its future commercialization.

Development of a New Timing System for ISIS

1247

R.A. Washington
STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom

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

1256

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

1264

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.

LImA2: Edge Distributed Acquisition and Processing Framework for High Performance 2D Detectors

1269

ESRF, Grenoble, France

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.

SOLEIL, Gif-sur-Yvette, France

SOLEIL is currently in the Technical Design Report (TDR) phase of a major upgrade of the facility. In its digital transformation, the development of processes and systems with a high degree of autonomy is at the center of the SOLEIL II project. One of the important components used to achieve a high degree of autonomy is the use of 6-axis robotic arms. Thus, in recent years, SOLEIL has developed and put into operation robotic applications to automate some processes of its beamlines and some processes of magnetic measurements of the insertion devices. The last year SOLEIL has been developing two new robotic applications, having thus continuity in the development of applications using its robotic standard. This paper describes these two new applications that being developed to automate the injection of liquid samples for BioSAXS experiments at the SWING beamline and to automate the mechanical and magnetic adjustment of the modules that compose an insertion device.

Ultra-High Throughput Automated Macromolecular Crystallography Data Collection Using the Bluesky Framework

1280

D.P. Perl, N. Frisina, D.E. Oram, N.P. Paterson
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.

Piezo Motor Based Hardware Triggered Nano Focus Caustic Acquisition

1285

LNLS, Campinas, Brazil

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

1290

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.

Jungfraujoch: Data Acquisition and Real-Time Image Analysis System for Kilohertz X-Ray Pixel Array Detector

Funding: F.L. acknowledges funding from the Open Research Data Program of the ETH Board and an innovation project supported by Innosuisse.
The Swiss Light Source (SLS) will shortly start an upgrade to become a 4th generation light source. The higher brilliance of the new source brings new science opportunities - one of them is improving time resolution for X-ray crystallography to a microsecond regime. However, fully utilizing the new machine will require increasing the frame rate of pixel array detectors and, thus, data volume. Nine-megapixel JUNGFRAU detector* planned for SLS 2.0 beamlines will generate up to 36 GB/s raw data when operated at 2 kHz**, which is very challenging for computing infrastructure. To operate this JUNGFRAU detector, PSI has developed a ’Jungfraujoch’ read-out system***. The system can handle the complete data rate within a single server box for fast deployment at various beamlines. The system uses FPGA smart network interface cards for data acquisition, GPUs for on-the-fly image analysis (e.g., spot finding, radial integration), and high-end CPUs for image compression. In the presentation, I will show Jungfraujoch’s capabilities, experience from time-resolved macromolecular crystallography beamtimes, and technical details. I will highlight how FPGA design with high-level languages (C/C++) can help software developers design programmable logic quickly and how it can help in rapid verification. I will also present experiences working with a memory-coherent interconnect (OpenCAPI) to integrate FPGA boards into the server system and how it compares with a mainstream peripheral bus (PCI Express).
