MO3BCO05	Online Models for X-ray Beamlines Using Sirepo-Bluesky	optics, radiation, electron, controls	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

TU2AO03	A Successful Emergency Response Plan: Lessons in the Controls Section of the ALBA Synchrotron	controls, operation, software, MMI	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.

TUMBCMO21	SOLEIL II: Towards A Major Transformation of the Facility	controls, experiment, operation, MMI	404
	Y.-M. Abiven, S.-E. Berrier, A. Buteau, I. Chado, E. Fonda, E. Frahi, B. Gagey, L.S. Nadolski, P. Pierrot SOLEIL, Gif-sur-Yvette, France
	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.

TUMBCMO34	Motion Control Architecture and Kinematics for Multi-DoF Kirkpatrick-Baez Focusing Mirrors System at LNLS-Sirius	controls, focusing, feedback, real-time	443
	J.P.S. Furtado, C.S.N.C. Bueno, J.V.E. Matoso, M.A. Montevechi Filho, G.B.Z.L. Moreno, T.R. Silva Soares LNLS, Campinas, Brazil
	Funding: Ministry of Science, Technology and Innovation (MCTI) 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.

TUPDP028	Challenges of the COSY Synchrotron Control System Upgrade to EPICS	controls, EPICS, power-supply, timing	561
	C. Böhme, C. Deliege, M. Simon, M. Thelen FZJ, Jülich, Germany V. Kamerdzhiev GSI, Darmstadt, Germany R. Modic, Z. Oven Cosylab, Ljubljana, Slovenia
	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.

Villanueva ALBA-CELLS, Cerdanyola del Vallès, Spain
	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.

TUPDP145	Position-Based Continuous Energy Scan Status at MAX IV	controls, experiment, undulator, detector	917
	Á. Freitas, N.S. Al-Habib, B. Bertrand, M. Eguiraun, I. Gorgisyan, A.F. Joubert, J. Lidón-Simon, M. Lindberg, C. Takahashi MAX IV Laboratory, Lund University, Lund, Sweden
	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.

WE3BCO06	Assonant: A Beamline-Agnostic Event Processing Engine for Data Collection and Standardization	experiment, controls, software, data-management	1025
	P.B. Mausbach, E.X. Miqueles, A. Pinto 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.

Syder DLS, Oxfordshire, United Kingdom
	The ICAT metadata catalogue is a flexible solution for managing scientific metadata and data from a wide variety of domains following the FAIR data principles. This paper will present an update of recent developments of the ICAT metadata catalogue and the latest status of the ICAT collaboration. ICAT was originally developed by UK Science and Technology Facilities Council (STFC) to manage the scientific data of ISIS Neutron and Muon Source and Diamond Light Source. They have since been joined by a number of other institutes including ESRF, HZB, SESAME, and ALBA who together now form the ICAT Collaboration [1]. ICAT has been used to manage petabytes of scientific data for ISIS, DLS, ESRF, HZB, and in the future SESAME and ALBA and make these data FAIR. The latest version of the ICAT core as well as the new user interfaces, DataGateway and DataHub, and extensions to ICAT for implementing free text searching, a common search interface across Photon and Neutron catalogues, a protocol-based interface that allows making the metadata available for findability, electronic logbooks, sample tracking, and web-based data and domain specific viewers developed by the community will be presented. Finally recent developments to use ICAT to develop applications for processed data with rich metadata in the fields of small angle scattering, macromolecular crystallography and cryo-electron microscopy will be described.

TH2BCO01	Synchronized Nonlinear Motion Trajectories at MAX IV Beamlines	detector, controls, vacuum, target	1160
	P. Sjöblom, H. Enquist, A. Freitas, J. Lidón-Simon, M. Lindberg, S. Malki 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.

THMBCMO22	Towards Defining a Synchronization Standard Between Beamline Components and Synchrotron Accelerators	experiment, interface, hardware, FPGA	1242

	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.

THMBCMO32	Robotic Process Automation: on the Continuity of Applications Development at SOLEIL	PLC, laser, injection, electron	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.

THPDP040	Control System of the ForMAX Beamline at the MAX IV Synchrotron	controls, detector, experiment, TANGO	1402
	W.T. Kitka S2Innovation, Kraków, Poland V. Da Silva, V.H. Haghighat, Y.L. Li, J. Lidón-Simon, M. Lindberg, S. Malki, K. Nygård, E. Rosendahl MAX IV Laboratory, Lund University, Lund, Sweden
	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.

THSDSC06	Developing a Digital Twin for BESSY II Synchrotron Light Source Based on EPICS and Microservice Design	EPICS, controls, lattice, monitoring	1594
	W. Sulaiman Khail, M. Ries, P. Schnitzer 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.

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.

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.

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.

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.

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.

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 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.

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

experiment, controls, software, 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.

The ICAT metadata catalogue is a flexible solution for managing scientific metadata and data from a wide variety of domains following the FAIR data principles. This paper will present an update of recent developments of the ICAT metadata catalogue and the latest status of the ICAT collaboration. ICAT was originally developed by UK Science and Technology Facilities Council (STFC) to manage the scientific data of ISIS Neutron and Muon Source and Diamond Light Source. They have since been joined by a number of other institutes including ESRF, HZB, SESAME, and ALBA who together now form the ICAT Collaboration [1]. ICAT has been used to manage petabytes of scientific data for ISIS, DLS, ESRF, HZB, and in the future SESAME and ALBA and make these data FAIR. The latest version of the ICAT core as well as the new user interfaces, DataGateway and DataHub, and extensions to ICAT for implementing free text searching, a common search interface across Photon and Neutron catalogues, a protocol-based interface that allows making the metadata available for findability, electronic logbooks, sample tracking, and web-based data and domain specific viewers developed by the community will be presented. Finally recent developments to use ICAT to develop applications for processed data with rich metadata in the fields of small angle scattering, macromolecular crystallography and cryo-electron microscopy will be described.

Synchronized Nonlinear Motion Trajectories at MAX IV Beamlines

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.

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.

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.

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.

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.
