	MAX~IV Laboratory, the first 4th generation synchrotron located in the south of Sweden, entered operation in 2017 with the first three experimental stations. In the past two years the project organisation has been focused on phase II of the MAX IV Laboratory development, aiming to raise the number of beamlines in operation to 16. The KITS group, responsible for the control and computing systems of the entire laboratory, was a major actor in the realisation of this phase as well as in the continuous up-keep of the user operation. The challenge consisted principally of establishing a clear project management plan for the support groups, including KITS, to handle this high load in an efficient and focused way, meanwhile gaining the experience of operating a 4th generation light source. The momentum gained was impacted by the last extensive shutdown due to the pandemic and shifted toward the remote user experiment, taking advantage of web technologies. This article focuses on how KITS has handled this growing phase in term of technology and organisation, to finally describe the new perspective for the MAX IV Laboratory, which will face a bright future.

MOPV006	The New Small Wheel Low Voltage Power Supply DCS for the ATLAS Experiment	controls, operation, experiment, radiation	111
	C. Paraskevopoulos NTUA, Athens, Greece
	The present ATLAS Small Wheel detector will be replaced with the New Small Wheel(NSW) which is expected to be installed in the ATLAS underground cavern by the end of the LS2. Due to its complexity and long-term operation, NSW requires the development of a sophisticated Detector Control System. The use of such a system is necessary to allow the detector to function consistently as a seamless interface to all sub-detectors and the technical infrastructure of the experiment. The central system handles the transition between the possible operating states while ensuring monitoring and archiving of the system’s parameters. The part that will be described is the modular system of Low Voltage. The new LV Intermediate Control Station will be used to power all the boards of the NSW and through them providing readout and trigger data while functioning safely. Among its core features are remote control, split of radiation sensitive parts from parts that can be housed in a hostile area and compatibility with operation under radiation and magnetic field as in the ATLAS cavern.

MOPV009	The HV DCS System for the New Small Wheel Upgrade of the ATLAS Experiment	controls, operation, hardware, status	115
	E. Karentzos CERN, Geneva, Switzerland
	The ATLAS muon spectrometer will exceed its design capabilities in the high background radiation as expected during the upcoming runs and at HL-LHC. In order to cope with the foreseen limitations, it was decided to replace the SW with a New SW (NSW) system, by combining two prototype detectors, the sTGC & and resistive Micromegas. Both technologies are ’aligned’ to the ATLAS general baselines for the NSW upgrade project, maintaining in such way the excellent performance of the muon system beyond Run-3. Complementary to the R&D of these detectors, an intuitive control system was of vital importance. The Micromegas DCS (MMG HV) and the sTGC DCS (STG HV) for the NSW have been developed, following closely the existing look, feel and command architecture of the other Muon sub-systems. The principal task of the DCS is to enable the coherent and safe operation of the detector by continuously monitoring its operational parameters and its overall state. Both technologies will be installed in ATLAS and will be readout and monitored through the common infrastructure. Aim of this work is the description of the development and implementation of a DCS for the HV system of both technologies. This paper has been submitted on behalf of the ATLAS Muon Collaboration

TUAL03	R&D Studies for the Atlas Tile Calorimeter Daughterboard	FPGA, radiation, electron, electronics	290
	E. Valdes Santurio, K.E. Dunne, S. Lee FYSIKUM, AlbaNova, Stockholm University, Stockholm, Sweden C. Bohm, H. Motzkau, S.B. Silverstein Stockholm University, Stockholm, Sweden
	The ATLAS Hadronic Calorimeter DaughterBoard (DB) interfaces the on-detector with the off-detector electronics. The DB features two 4.6 Gbps downlinks and two pairs of 9.6 Gbps uplinks powered by four SFP+ Optical transceivers. The downlinks receive configuration commands and LHC timing to be propagated to the front-end, and the uplinks transmit continuous high-speed readout of digitized PMT samples, detector control system and monitoring data. The design minimizes single points of failure and mitigates radiation damage by means of a double-redundant scheme. To mitigate Single Event Upset rates, Xilinx Soft Error Mitigation and Triple Mode Redundancy are used. Reliability in the high speed links is achieve by adopting Cyclic Redundancy Check in the uplinks and Forward Error Correction in the downlinks. The DB features a dedicated Single Event Latch-up protection circuitry that power-cycles the board in the case of any over-current event avoiding any possible hardware damages. We present a summary of the studies performed to verify the reliability if the performance of the DB revision 6, and the radiation qualification tests of the components used for the design.

TUAR01	Upgrade of the CMS ECAL Detector Control System During the CERN Large Hadron Collider Long Shutdown II	controls, software, framework, operation	297
	L. Marchese, D.R.S. Di Calafiori, G. Dissertori, L. Djambazov, R. Jiménez Estupiñán, W. Lustermann ETH, Zurich, Switzerland
	As part of the Compact Muon Solenoid (CMS) experiment, the Electromagnetic Calorimeter (ECAL) Detector Control System (DCS) is undergoing a large software and hardware upgrade during the second long shutdown (LS2) of the CERN Large Hadron Collider (LHC). The DCS software running under the WinCC Open Architecture (OA) platform, required fundamental changes in the architecture as well as several other upgrades on the hardware side. The extension of the current long shutdown (2019-2021) is offering a unique opportunity to perform more updates, improve the detector safety and robustness during operations and achieve new control features with an increased modularity of the software architecture. Starting from the main activities of the ECAL DCS upgrade plan, we present the updated agenda for the LS2. This covers several aspects such as the different software migrations of the DCS, the consolidation of toolkits as well as some other improvements preceding the major ECAL upgrade foreseen for the next long shutdown (2025-2026).

	The Indian-based Neutrino Observatory collaboration has proposed to build a 50 KT magnetized Iron Calorimeter (ICAL) detector to study atmospheric neutrinos. The paper describes the design of back-end event builder for Mini-ICAL, which is a first prototype version of ICAL and consists of 20 Resistive Plate Chamber (RPC) detectors. The RPCs push the event and monitoring data using a multi-tier network technology to the event builder which carries out event building, event track display, data quality monitoring and data archival functions. The software has been designed for high performance and scalability using asynchronous data acquisition and lockless concurrent data structures. Data storage mechanisms like ROOT, Berkeley DB, Binary and Protocol Buffers were studied for performance and suitability. Server data push module designed using publish-subscribe pattern allowed transport & remote client implementation technology agnostic. Event Builder has been deployed at mini-ICAL with a throughput of 3MBps. Since the software modules have been designed for scalability, they can be easily adapted for the next prototype E-ICAL with 320 RPCs to have sustained data rate of 200MBps

TUPV025	Control System of Upgraded High Voltage for Atlas Tile Calorimeter	controls, software, interface, electron	443
	F. Martins, F.M.O. Cuim, G.G. Evans, R.P. Fernandez, A. Gomes, L. Gurriana LIP, Lisboa, Portugal J.A. Soares Augusto FCUL, Lisboa, Portugal
	The preparation of the upgrade of the ATLAS electronics for the High Luminosity LHC is in full swing. The Tile Calorimeter is preparing the upgrade of its readout electronics and power distribution systems. One of such systems is the High Voltage (HV) regulation and distribution system. The new system is based on HVRemote boards mounted in crates located at the counting room. The HV will be delivered to the on-detector electronics using 100 m long cables. The crates will be equipped with a system-on-chip that will be responsible for the control and monitoring of the HV boards. The control of the HVRemote and its dedicated HVSupply boards is done by means of a serial peripheral interface bus. A SCADA component is under development to communicate with and supervise the crates and boards, and to integrate the HV system in the control system of the detector. The control system will be able to send notifications to the operators when the monitored values are out of range, archive the monitored data and if required, perform automated actions.

TUPV030	Redesign of the VELO Thermal Control System Forfuture Detector Development	controls, experiment, framework, PLC	454
	S.A. Lunt UCT Physics, Cape Town, South Africa B. Verlaat, L. Zwalinski CERN, Geneva, Switzerland
	The Detector Technologies group at CERN has developed a Two-Phase Accumulator Controlled Loop (2PACL) test system for future detector development, using reused hardware from the LHCb Vertex Locator (VELO) Thermal Control System. The fluid, electrical and control systems have been redesigned and simplified by removing redundant components because it is no longer a critical system. The fluid cycle was updated to allow both 2PACL and integrated 2PACL cycles to be run and the chiller was replaced with an air-cooled unit using hot gas bypass to achieve a high turndown ratio. The electrical systems were upgraded with new hardware to improve usability and practicality. The control system logic is being developed with the CERN’s Unified Industrial Control System (UNICOS) framework. This paper presents thedetails of the design and implementation.

TUPV042	Collision Avoidance Systems in Synchrotron SOLEIL	controls, PLC, experiment, synchrotron	501

	Beamlines at Synchrotron SOLEIL are finding that their experimental setups (in respect to their respective sample environments, mechanical systems, and detectors) are getting more constrained when it comes to motorized manoeuvrability - an increasing number of mechanical instruments are being actuated within the same workspace hence increasing the risk of collision. We will in this paper outline setups with two types of Collision Avoidance Systems (CAS): (1) Static-CAS applications, currently being employed at the PUMA and NANOSCOPIUM beamlines, that use physical or contactless sensors coupled with PLC- and motion control- systems; (2) Dynamic-CAS applications, that use dynamic anti-collision algorithms combining encoder feedback and 3D-models of the system environment, implemented at the ANTARES and MARS beamlines but applied using two different strategies.

TUPV050	Control System Upgrade of the High-Pressure Cell for Pressure-Jump X-Ray Diffraction	controls, EPICS, operation, network	524
	R. Mercado, N.L. Griffin, P. Holloway, S.C. Lay, P.J. Roberts DLS, Oxfordshire, United Kingdom
	This paper reports on the upgrade of the control system of a sample environment used to pressurise samples to 500 MPa at temperatures between -20 °C and 120 °C. The equipment can achieve millisecond pressure jumps for use in X-ray scattering experiments. It has been routinely available in beamline I22 at Diamond. The millisecond pressure-jump capability is unique. Example applications were the demonstration of pressure-induced formation of super crystals from PEGylated gold nanoparticles and the study of controlled assembly and disassembly of nanoscale protein cages. The project goal was to migrate the control system for the improved integration to EPICS and the GDA data acquisition software. The original control system uses National Instruments hardware controlled from LabView. The project looked at mapping the old control system hardware to alternatives in use at Diamond and migrating the control software. The paper discusses the choice of equipment used for ADC acquisition and equipment protection, using Omron PLCs and Beckhoff EtherCAT modules, a custom jump-trigger circuit, the calibration of the system and the next steps for testing the system.

WEPV002	Position Scanning Solutions at the TARUMÃ Station at the CARNAÚBA Beamline at Sirius/LNLS	controls, experiment, MMI, operation	613
	C.S.N.C. Bueno, L.G. Capovilla, R.R. Geraldes, L.C. Guedes, G.N. Kontogiorgos, L. Martins dos Santos, M.A.L. Moraes, G.B.Z.L. Moreno, A.C. Piccino Neto, J.R. Piton, H.C.N. Tolentino LNLS, Campinas, Brazil
	Funding: Ministry of Science, Technology and Innovation (MCTI) TARUMÃ is the sub-microprobe station of the CARNAÚBA beamline at Sirius/LNLS. Covering the range from 2.05 to 15keV, the probe consists of a fully-coherent monochromatic beam varying from 550 to 120nm with flux of up to 1e11ph/s/100mA after the achromatic focusing optics. Hence, positioning requirements span from nanometer-level errors for high-resolution experiments to fast continuous trajectories for high throughput, whereas a large flexibility is required for different sample setups and simultaneous multi-technique X-ray analyses, including tomography. To achieve this, the overall architecture of the station relies on a pragmatic sample positioning solution, with a rotation stage with a range of 220°, coarse stages for sub-micrometer resolution in a range of 20mm in XYZ and a fine piezo stage for nanometer resolution in a range of 0.3mm in XYZ. Typical scans consist of continuous raster 2D trajectories perpendicularly to the beam, over ranges that vary from tens to hundreds of micrometers, with acquisition times in range of milliseconds. Positioning is based on 4th order trajectories and feedforward, triggering includes the multiple detectors and data storage is addressed Geraldes, R.R., et al. ’Design and Commissioning of the TARUMÃ Station at the CARNAÚBA Beamline at Sirius/LNLS’ Proc. MEDSI20 (2020).

WEPV005	Experiment Automation Using EPICS	EPICS, controls, experiment, network	625
	D.D. Cosic, M. Vićentijević RBI, Zagreb, Croatia
	Beam time at accelerator facilities around the world is very expensive and scarce, prompting the need for experiments to be performed as efficiently as possible. Efficiency of an accelerator facility is measured as a ratio of experiment time to beam optimization time. At RBI we have four ion sources, two accelerators, ten experimental end stations. We can obtain around 50 different ion species, each requiring a different set of parameters for optimal operation. Automating repetitive procedures can increase efficiency of an experiment and beam setup time. Currently, operators manually fine tunes the parameters to optimize the beam current. This process can be very long and requires many iterations. Automatic optimization of parameters can save valuable accelerator time. Based on a successful implementation of EPICS, the system was expanded to automate reoccurring procedures. To achieve this, a PLC was integrated into EPICS and our acquisition system was modified to communicate with devices through EPICS. This allowed us to use tools available in EPICS to do beam optimization much faster than a human operator can, and therefore significantly increased the efficiency of our facility.

WEPV021	Machine Learning for RF Breakdown Detection at CLARA	cavity, network, gun, operation	681
	A.E. Pollard, D.J. Dunning, A.J. Gilfellon STFC/DL/ASTeC, Daresbury, Warrington, Cheshire, United Kingdom
	Maximising the accelerating gradient of RF structures is fundamental to improving accelerator facility performance and cost-effectiveness. Structures must be subjected to a conditioning process before operational use, in which the gradient is gradually increased up to the operating value. A limiting effect during this process is breakdown or vacuum arcing, which can cause damage that limits the ultimate operating gradient. Techniques to efficiently condition the cavities while minimising the number of breakdowns are therefore important. In this paper, machine learning techniques are applied to detect breakdown events in RF pulse traces by approaching the problem as anomaly detection, using a variational autoencoder. This process detects deviations from normal operation and classifies them with near perfect accuracy. Offline data from various sources has been used to develop the techniques, which we aim to test at the CLARA facility at Daresbury Laboratory. These techniques could then be applied generally.

THBL04	Kubernetes for EPICS IOCs	EPICS, network, controls, target	835
	G. Knap, T.M. Cobb, Y. Moazzam, U.K. Pedersen, C.J. Reynolds DLS, Oxfordshire, United Kingdom
	EPICS IOCs at Diamond Light Source are built, deployed, and managed by a set of in-house tools that were implemented 15 years ago. This paper will detail a proof of concept to demonstrate replacing these tools and processes with modern industry standards. IOCs are packaged in containers with their unique dependencies included. IOC images are generic, and a single image is required for all containers that control a given class of device. Configuration is provided to the container in the form of a start-up script only. The configuration allows the generic IOC image to bootstrap a container for a unique IOC instance. This approach keeps the number of images required to a minimum. Container orchestration for all beamlines in the facility is provided through a central Kubernetes cluster. The cluster has remote nodes that reside within each beamline network to host the IOCs for the local beamline. All source, images and individual IOC configurations are held in repositories. Build and deployment to the production registries is handled by continuous integration. Finally, a development container provides a portable development environment for maintaining and testing IOC code.

THPV032	The Demonstrator of the HL-LHC ATLAS Tile Calorimeter	electron, electronics, high-voltage, hadron	935
	P. Tsotskolauri Tbilisi State University, T’bilisi, Georgia
	The High Luminosity Large Hadron Collider (HL-LHC) has motivated R&D to upgrade the ATLAS Tile Calorimeter. The new system consists on an optimized analogue design engineered with selected radiation-tolerant COTS and redundancy layers to avoid single points of failure. The design will provide better timing, improved energy resolution, lower noise and less sensitivity to out-of-time pileup. Multiple types of FPGAs, CERN custom rad-hard ASICs (GBTx), and multi-Gbps optical links are used to distribute LHC timing, read out fully digital data of the whole TileCal, transmit timing and calibrated energy per cell to the Trigger system at 40 MHz, and provide triggered data at 1 MHz. To test the upgraded electronics in real ATLAS conditions, a hybrid demonstrator prototype module containing the new calorimeter module electronics, but still compatible with TileCal’s legacy system was tested in ATLAS during 2019-2021. An upgraded version of the demonstrator with finalized HL-LHC electronics is being assembled to be tested in testbeam campaigns at the Super Proton Syncrotron (SPS) at CERN. We present current status and results for the different tests done with the upgraded demonstrator system. Presented on behalf of the ATLAS Tile Calorimeter System

THPV038	Plug-in-Based Ptychography & CDI Reconstruction User Interface Development	interface, operation, framework, synchrotron	950
	S.W. Kim, K.H. Ku, W.W. Lee PAL, Pohang, Republic of Korea
	Synchrotron beamlines have a wide range of fields, and accordingly, various open source and commercial softwares are being used for data analysis. Inevitable, the user interface differs between programs and there is little shared part, so the user had to spend a lot of effort to perform a new experimental analysis and learn how to use the program newly. In order to overcome these shortcomings, the same user interface was maintained using the Xi-cam framework, and different analysis algorithms for each field were introduced in a plugin method. In this presentation, user interfaces designed for ptychography and cdi reconstruction will be introduced.

THPV043	Using AI for Management of Field Emission in SRF Linacs	radiation, cavity, operation, linac	970
	A. Carpenter, P. Degtiarenko, R. Suleiman, C. Tennant, D.L. Turner, L.S. Vidyaratne JLab, Newport News, Virginia, USA K.M. Iftekharuddin, M. Rahman ODU, Norfolk, Virginia, USA
	Funding: This work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics under Contract No. DE-AC05-06OR23177. Field emission control, mitigation, and reduction is critical for reliable operation of high gradient superconducting radio-frequency (SRF) accelerators. With the SRF cavities at high gradients, the field emission of electrons from cavity walls can occur and will impact the operational gradient, radiological environment via activated components, and reliability of CEBAF’s two linacs. A new effort has started to minimize field emission in the CEBAF linacs by re-distributing cavity gradients. To measure radiation levels, newly designed neutron and gamma radiation dose rate monitors have been installed in both linacs. Artificial intelligence (AI) techniques will be used to identify cavities with high levels of field emission based on control system data such as radiation levels, cryogenic readbacks, and vacuum loads. The gradients on the most offending cavities will be reduced and compensated for by increasing the gradients on least offensive cavities. Training data will be collected during this year’s operational program and initial implementation of AI models will be deployed. Preliminary results and future plans are presented.

THPV048	Novel Control System for the LHCb Scintillating Fibre Tracker Detector Infrastructure	controls, PLC, vacuum, electron	981
	M. Ostrega, M.A. Ciupinski, S. Jakobsen, X. Pons CERN, Geneva, Switzerland
	During the Long Shutdown 2 of the LHC at CERN, the LHCb detector is upgraded to cope with higher instantaneous luminosities. The largest of the new trackers is based on the scintillating fibres (SciFi) read out by SIlicon PhotoMultipliers (SiPMs). The SiPMs will be cooled down to -40°C to minimize noise. For performance and space reasons, the cooling lines are vacuum insulated. Ionizing radiation requires detaching and displace the readout electronics from Pirani gauges to a lower radiation area. To avoid condensation inside the SiPM boxes, the atmosphere inside must have a dew point of at most -45°C. The low dew point will be achieved by flushing a dry gas through the box. 576 flowmeters devices will be installed to monitor the gas flow continuously. A Condensation Prevention System (CPS) has been introduced as condensation was observed. The CPS powers heating wires installed around the SiPM boxes and the vacuum bellows isolating the cooling lines. The CPS also includes 672 temperature sensors to monitor that all parts are warmer than the cavern dew point. The temperature readout systems are based on multiplexing technology at the in the front-end and a PLC in the back-end.

	The present ATLAS Small Wheel Muon detector will be replaced with a New Small Wheel(NSW) detector in order to cope up with the future LHC runs of high luminosity. One crucial part of the integration procedure concerns the validation of the electronics for a system with more than 2.1 M electronic channels. The readout chain is based on optical link technology connecting the backend to the front-end electronics via the FELIX, which is a newly developed system that will serve as the next generation readout driver for ATLAS. For the configuration, calibration and monitoring path the various electronics boards are supplied with the GBT-SCA ASIC and its purpose is to distribute control and monitoring signals to the electronics. Due to its complexity, NSW electronics requires the development of a sophisticated Control System. The use of such a system is necessary to allow the electronics to function consistently, safely and as a seamless interface to all sub-detectors and the technical infrastructure of the experiment. The central system handles the transition between the probe’s possible operating states while ensuring continuous monitoring and archiving of the system’s operating parameters.

FRBL05	RemoteVis: An Efficient Library for Remote Visualization of Large Volumes Using NVIDIA Index	software, synchrotron, GPU, network	1047

	Funding: We would like to thank the Brazilian Ministry of Science, Technology, and Innovation for the financial support. Advancements in X-ray detector technology are increasing the amount of volumetric data available for material analysis in synchrotron light sources. Such developments are driving the creation of novel solutions to visualize large datasets both during and after image acquisition. Towards this end, we have devised a library called RemoteVis to visualize large volumes remotely in HPC nodes, using NVIDIA IndeX as the rendering backend. RemoteVis relies on RDMA-based data transfer to move large volumes from local HPC servers, possibly connected to X-ray detectors, to remote dedicated nodes containing multiple GPUs for distributed volume rendering. RemoteVis then injects the transferred data into IndeX for rendering. IndeX is a scalable software capable of using multiple nodes and GPUs to render large volumes in full resolution. As such, we have coupled RemoteVis with slurm to dynamically schedule one or multiple HPC nodes to render any given dataset. RemoteVis was written in C/C++ and Python, providing an efficient API that requires only two functions to 1) start remote IndeX instances and 2) render regular volumes and point-cloud (diffraction) data on the web browser/Jupyter client. *NVIDIA IndeX, https://developer.nvidia.com/nvidia-index

FRBR01	Process Automation at SOLEIL: Two Applications Using Robot Manipulators	synchrotron, controls, experiment, undulator	1054

	Robot manipulators are an important component in most autonomous systems in the industry. Arc welding, machine tending, painting, picking, are only some examples where the robot manipulators are widely employed. In Synchrotrons some process can benefit from robotic approaches in order to improve automation. Automatic Sample Changer on beamlines is the most common example of automation. This paper describes two robotic applications developed at Synchrotron SOLEIL. Both applications use the SOLEIL robotic standard introduced some years ago [1]. The first application aims to automate the exchange of samples for powder diffraction experiment on the CRISTAL beamline. Hence, a pick-and-place robot is used to automate the process of picking up the sample holders and placing them on the goniometer. The second application, also of the pick-and-place type, is dedicated to the automation of the magnetic characterization of magnet modules of an U15 undulator. These modules, built with a permanent magnet and two poles, are measured using a pulsed wire method [2]. In this case, the robot picks the modules stored in boxes to then place them on the test bench of the U15 undulator. Y.-M.

FRBR03	Status of Bluesky Deployment at BESSY II	controls, EPICS, interface, experiment	1064
	W. Smith, S. Kazarski, R. Müller, P. Schnizer, S. Vadilonga, L. Vera Ramiréz HZB, Berlin, Germany
	The modernization plan for the experimental DAQ at the BESSY II is underpinned by the capabilities provided by the Bluesky software ecosystem. To interface with the hardware Bluesky relies on the Ophyd library, that provides a consistent high-level interface across a wide-range of devices. Many elements of the accelerator, some beamlines and endstations are adopting the Bluesky software. To meet FAIR data obligations, the capture of metadata with Bluesky and the export into a permanent and easily accessible storage called ICAT are investigated. Finally, initial studies to investigate the integration of ML methods, like reinforcement learning were performed. This paper reports on the work that has been done so far at BESSY II to adopt Bluesky, problems that have been overcome and lessons learned.

FRBR04	Continuous Scans with Position Based Hardware Triggers	controls, undulator, hardware, synchrotron	1069
	H. Enquist, A. Bartalesi, B. Bertrand, J. Forsberg, A. Freitas, V. Hardion, M. Lindberg, C. Takahashi MAX IV Laboratory, Lund University, Lund, Sweden
	At beamline end-stations, data taking that relies on traditional step scanning, in which motors are repeatedly started and stopped, leads to inefficient usage of the x-ray source. This also increases the risk of sample radiation damage. We have developed a system where scans are performed while continuously moving the motors. To ensure stable repeatable measurements, the detector triggers are generated, in hardware, from the motor encoder positions. Before the scan starts, a list of positions is generated and as the scan progresses a trigger is produced as each successive position in the list is reached. The encoder signals from the motors are connected both to the IcePAP motion controller for closed loop operation, and a PandABox which is used as the trigger source. Control is from Tango and Sardana with a TriggerGate controller that calculates the motor positions and configures the PandABox. The scanned motor can be either a single motor, for example a sample positioner, or a combined motion like a monochromator. When combined motions are required, these make use of the parametric trajectory mode of the IcePAP. This enables continuous scans of coupled axes with non-linear paths.

MAX~IV Laboratory, the first 4th generation synchrotron located in the south of Sweden, entered operation in 2017 with the first three experimental stations. In the past two years the project organisation has been focused on phase II of the MAX IV Laboratory development, aiming to raise the number of beamlines in operation to 16. The KITS group, responsible for the control and computing systems of the entire laboratory, was a major actor in the realisation of this phase as well as in the continuous up-keep of the user operation. The challenge consisted principally of establishing a clear project management plan for the support groups, including KITS, to handle this high load in an efficient and focused way, meanwhile gaining the experience of operating a 4th generation light source. The momentum gained was impacted by the last extensive shutdown due to the pandemic and shifted toward the remote user experiment, taking advantage of web technologies. This article focuses on how KITS has handled this growing phase in term of technology and organisation, to finally describe the new perspective for the MAX IV Laboratory, which will face a bright future.

C. Paraskevopoulos
NTUA, Athens, Greece

The present ATLAS Small Wheel detector will be replaced with the New Small Wheel(NSW) which is expected to be installed in the ATLAS underground cavern by the end of the LS2. Due to its complexity and long-term operation, NSW requires the development of a sophisticated Detector Control System. The use of such a system is necessary to allow the detector to function consistently as a seamless interface to all sub-detectors and the technical infrastructure of the experiment. The central system handles the transition between the possible operating states while ensuring monitoring and archiving of the system’s parameters. The part that will be described is the modular system of Low Voltage. The new LV Intermediate Control Station will be used to power all the boards of the NSW and through them providing readout and trigger data while functioning safely. Among its core features are remote control, split of radiation sensitive parts from parts that can be housed in a hostile area and compatibility with operation under radiation and magnetic field as in the ATLAS cavern.

E. Karentzos
CERN, Geneva, Switzerland

The ATLAS muon spectrometer will exceed its design capabilities in the high background radiation as expected during the upcoming runs and at HL-LHC. In order to cope with the foreseen limitations, it was decided to replace the SW with a New SW (NSW) system, by combining two prototype detectors, the sTGC & and resistive Micromegas. Both technologies are ’aligned’ to the ATLAS general baselines for the NSW upgrade project, maintaining in such way the excellent performance of the muon system beyond Run-3. Complementary to the R&D of these detectors, an intuitive control system was of vital importance. The Micromegas DCS (MMG HV) and the sTGC DCS (STG HV) for the NSW have been developed, following closely the existing look, feel and command architecture of the other Muon sub-systems. The principal task of the DCS is to enable the coherent and safe operation of the detector by continuously monitoring its operational parameters and its overall state. Both technologies will be installed in ATLAS and will be readout and monitored through the common infrastructure. Aim of this work is the description of the development and implementation of a DCS for the HV system of both technologies.
This paper has been submitted on behalf of the ATLAS Muon Collaboration

The ATLAS Hadronic Calorimeter DaughterBoard (DB) interfaces the on-detector with the off-detector electronics. The DB features two 4.6 Gbps downlinks and two pairs of 9.6 Gbps uplinks powered by four SFP+ Optical transceivers. The downlinks receive configuration commands and LHC timing to be propagated to the front-end, and the uplinks transmit continuous high-speed readout of digitized PMT samples, detector control system and monitoring data. The design minimizes single points of failure and mitigates radiation damage by means of a double-redundant scheme. To mitigate Single Event Upset rates, Xilinx Soft Error Mitigation and Triple Mode Redundancy are used. Reliability in the high speed links is achieve by adopting Cyclic Redundancy Check in the uplinks and Forward Error Correction in the downlinks. The DB features a dedicated Single Event Latch-up protection circuitry that power-cycles the board in the case of any over-current event avoiding any possible hardware damages. We present a summary of the studies performed to verify the reliability if the performance of the DB revision 6, and the radiation qualification tests of the components used for the design.

As part of the Compact Muon Solenoid (CMS) experiment, the Electromagnetic Calorimeter (ECAL) Detector Control System (DCS) is undergoing a large software and hardware upgrade during the second long shutdown (LS2) of the CERN Large Hadron Collider (LHC). The DCS software running under the WinCC Open Architecture (OA) platform, required fundamental changes in the architecture as well as several other upgrades on the hardware side. The extension of the current long shutdown (2019-2021) is offering a unique opportunity to perform more updates, improve the detector safety and robustness during operations and achieve new control features with an increased modularity of the software architecture. Starting from the main activities of the ECAL DCS upgrade plan, we present the updated agenda for the LS2. This covers several aspects such as the different software migrations of the DCS, the consolidation of toolkits as well as some other improvements preceding the major ECAL upgrade foreseen for the next long shutdown (2025-2026).

The Indian-based Neutrino Observatory collaboration has proposed to build a 50 KT magnetized Iron Calorimeter (ICAL) detector to study atmospheric neutrinos. The paper describes the design of back-end event builder for Mini-ICAL, which is a first prototype version of ICAL and consists of 20 Resistive Plate Chamber (RPC) detectors. The RPCs push the event and monitoring data using a multi-tier network technology to the event builder which carries out event building, event track display, data quality monitoring and data archival functions. The software has been designed for high performance and scalability using asynchronous data acquisition and lockless concurrent data structures. Data storage mechanisms like ROOT, Berkeley DB, Binary and Protocol Buffers were studied for performance and suitability. Server data push module designed using publish-subscribe pattern allowed transport & remote client implementation technology agnostic. Event Builder has been deployed at mini-ICAL with a throughput of 3MBps. Since the software modules have been designed for scalability, they can be easily adapted for the next prototype E-ICAL with 320 RPCs to have sustained data rate of 200MBps

The preparation of the upgrade of the ATLAS electronics for the High Luminosity LHC is in full swing. The Tile Calorimeter is preparing the upgrade of its readout electronics and power distribution systems. One of such systems is the High Voltage (HV) regulation and distribution system. The new system is based on HVRemote boards mounted in crates located at the counting room. The HV will be delivered to the on-detector electronics using 100 m long cables. The crates will be equipped with a system-on-chip that will be responsible for the control and monitoring of the HV boards. The control of the HVRemote and its dedicated HVSupply boards is done by means of a serial peripheral interface bus. A SCADA component is under development to communicate with and supervise the crates and boards, and to integrate the HV system in the control system of the detector. The control system will be able to send notifications to the operators when the monitored values are out of range, archive the monitored data and if required, perform automated actions.

The Detector Technologies group at CERN has developed a Two-Phase Accumulator Controlled Loop (2PACL) test system for future detector development, using reused hardware from the LHCb Vertex Locator (VELO) Thermal Control System. The fluid, electrical and control systems have been redesigned and simplified by removing redundant components because it is no longer a critical system. The fluid cycle was updated to allow both 2PACL and integrated 2PACL cycles to be run and the chiller was replaced with an air-cooled unit using hot gas bypass to achieve a high turndown ratio. The electrical systems were upgraded with new hardware to improve usability and practicality. The control system logic is being developed with the CERN’s Unified Industrial Control System (UNICOS) framework. This paper presents thedetails of the design and implementation.

Beamlines at Synchrotron SOLEIL are finding that their experimental setups (in respect to their respective sample environments, mechanical systems, and detectors) are getting more constrained when it comes to motorized manoeuvrability - an increasing number of mechanical instruments are being actuated within the same workspace hence increasing the risk of collision. We will in this paper outline setups with two types of Collision Avoidance Systems (CAS): (1) Static-CAS applications, currently being employed at the PUMA and NANOSCOPIUM beamlines, that use physical or contactless sensors coupled with PLC- and motion control- systems; (2) Dynamic-CAS applications, that use dynamic anti-collision algorithms combining encoder feedback and 3D-models of the system environment, implemented at the ANTARES and MARS beamlines but applied using two different strategies.

DLS, Oxfordshire, United Kingdom

This paper reports on the upgrade of the control system of a sample environment used to pressurise samples to 500 MPa at temperatures between -20 °C and 120 °C. The equipment can achieve millisecond pressure jumps for use in X-ray scattering experiments. It has been routinely available in beamline I22 at Diamond. The millisecond pressure-jump capability is unique. Example applications were the demonstration of pressure-induced formation of super crystals from PEGylated gold nanoparticles and the study of controlled assembly and disassembly of nanoscale protein cages. The project goal was to migrate the control system for the improved integration to EPICS and the GDA data acquisition software. The original control system uses National Instruments hardware controlled from LabView. The project looked at mapping the old control system hardware to alternatives in use at Diamond and migrating the control software. The paper discusses the choice of equipment used for ADC acquisition and equipment protection, using Omron PLCs and Beckhoff EtherCAT modules, a custom jump-trigger circuit, the calibration of the system and the next steps for testing the system.

Funding: Ministry of Science, Technology and Innovation (MCTI)
TARUMÃ is the sub-microprobe station of the CARNAÚBA beamline at Sirius/LNLS*. Covering the range from 2.05 to 15keV, the probe consists of a fully-coherent monochromatic beam varying from 550 to 120nm with flux of up to 1e11ph/s/100mA after the achromatic focusing optics. Hence, positioning requirements span from nanometer-level errors for high-resolution experiments to fast continuous trajectories for high throughput, whereas a large flexibility is required for different sample setups and simultaneous multi-technique X-ray analyses, including tomography. To achieve this, the overall architecture of the station relies on a pragmatic sample positioning solution, with a rotation stage with a range of 220°, coarse stages for sub-micrometer resolution in a range of 20mm in XYZ and a fine piezo stage for nanometer resolution in a range of 0.3mm in XYZ. Typical scans consist of continuous raster 2D trajectories perpendicularly to the beam, over ranges that vary from tens to hundreds of micrometers, with acquisition times in range of milliseconds. Positioning is based on 4th order trajectories and feedforward, triggering includes the multiple detectors and data storage is addressed

Experiment Automation Using EPICS

RBI, Zagreb, Croatia

Beam time at accelerator facilities around the world is very expensive and scarce, prompting the need for experiments to be performed as efficiently as possible. Efficiency of an accelerator facility is measured as a ratio of experiment time to beam optimization time. At RBI we have four ion sources, two accelerators, ten experimental end stations. We can obtain around 50 different ion species, each requiring a different set of parameters for optimal operation. Automating repetitive procedures can increase efficiency of an experiment and beam setup time. Currently, operators manually fine tunes the parameters to optimize the beam current. This process can be very long and requires many iterations. Automatic optimization of parameters can save valuable accelerator time. Based on a successful implementation of EPICS, the system was expanded to automate reoccurring procedures. To achieve this, a PLC was integrated into EPICS and our acquisition system was modified to communicate with devices through EPICS. This allowed us to use tools available in EPICS to do beam optimization much faster than a human operator can, and therefore significantly increased the efficiency of our facility.

Machine Learning for RF Breakdown Detection at CLARA

Maximising the accelerating gradient of RF structures is fundamental to improving accelerator facility performance and cost-effectiveness. Structures must be subjected to a conditioning process before operational use, in which the gradient is gradually increased up to the operating value. A limiting effect during this process is breakdown or vacuum arcing, which can cause damage that limits the ultimate operating gradient. Techniques to efficiently condition the cavities while minimising the number of breakdowns are therefore important. In this paper, machine learning techniques are applied to detect breakdown events in RF pulse traces by approaching the problem as anomaly detection, using a variational autoencoder. This process detects deviations from normal operation and classifies them with near perfect accuracy. Offline data from various sources has been used to develop the techniques, which we aim to test at the CLARA facility at Daresbury Laboratory. These techniques could then be applied generally.

EPICS IOCs at Diamond Light Source are built, deployed, and managed by a set of in-house tools that were implemented 15 years ago. This paper will detail a proof of concept to demonstrate replacing these tools and processes with modern industry standards. IOCs are packaged in containers with their unique dependencies included. IOC images are generic, and a single image is required for all containers that control a given class of device. Configuration is provided to the container in the form of a start-up script only. The configuration allows the generic IOC image to bootstrap a container for a unique IOC instance. This approach keeps the number of images required to a minimum. Container orchestration for all beamlines in the facility is provided through a central Kubernetes cluster. The cluster has remote nodes that reside within each beamline network to host the IOCs for the local beamline. All source, images and individual IOC configurations are held in repositories. Build and deployment to the production registries is handled by continuous integration. Finally, a development container provides a portable development environment for maintaining and testing IOC code.

The High Luminosity Large Hadron Collider (HL-LHC) has motivated R&D to upgrade the ATLAS Tile Calorimeter. The new system consists on an optimized analogue design engineered with selected radiation-tolerant COTS and redundancy layers to avoid single points of failure. The design will provide better timing, improved energy resolution, lower noise and less sensitivity to out-of-time pileup. Multiple types of FPGAs, CERN custom rad-hard ASICs (GBTx), and multi-Gbps optical links are used to distribute LHC timing, read out fully digital data of the whole TileCal, transmit timing and calibrated energy per cell to the Trigger system at 40 MHz, and provide triggered data at 1 MHz. To test the upgraded electronics in real ATLAS conditions, a hybrid demonstrator prototype module containing the new calorimeter module electronics, but still compatible with TileCal’s legacy system was tested in ATLAS during 2019-2021. An upgraded version of the demonstrator with finalized HL-LHC electronics is being assembled to be tested in testbeam campaigns at the Super Proton Syncrotron (SPS) at CERN. We present current status and results for the different tests done with the upgraded demonstrator system.

Synchrotron beamlines have a wide range of fields, and accordingly, various open source and commercial softwares are being used for data analysis. Inevitable, the user interface differs between programs and there is little shared part, so the user had to spend a lot of effort to perform a new experimental analysis and learn how to use the program newly. In order to overcome these shortcomings, the same user interface was maintained using the Xi-cam framework, and different analysis algorithms for each field were introduced in a plugin method. In this presentation, user interfaces designed for ptychography and cdi reconstruction will be introduced.

Field emission control, mitigation, and reduction is critical for reliable operation of high gradient superconducting radio-frequency (SRF) accelerators. With the SRF cavities at high gradients, the field emission of electrons from cavity walls can occur and will impact the operational gradient, radiological environment via activated components, and reliability of CEBAF’s two linacs. A new effort has started to minimize field emission in the CEBAF linacs by re-distributing cavity gradients. To measure radiation levels, newly designed neutron and gamma radiation dose rate monitors have been installed in both linacs. Artificial intelligence (AI) techniques will be used to identify cavities with high levels of field emission based on control system data such as radiation levels, cryogenic readbacks, and vacuum loads. The gradients on the most offending cavities will be reduced and compensated for by increasing the gradients on least offensive cavities. Training data will be collected during this year’s operational program and initial implementation of AI models will be deployed. Preliminary results and future plans are presented.

981

CERN, Geneva, Switzerland

During the Long Shutdown 2 of the LHC at CERN, the LHCb detector is upgraded to cope with higher instantaneous luminosities. The largest of the new trackers is based on the scintillating fibres (SciFi) read out by SIlicon PhotoMultipliers (SiPMs). The SiPMs will be cooled down to -40°C to minimize noise. For performance and space reasons, the cooling lines are vacuum insulated. Ionizing radiation requires detaching and displace the readout electronics from Pirani gauges to a lower radiation area. To avoid condensation inside the SiPM boxes, the atmosphere inside must have a dew point of at most -45°C. The low dew point will be achieved by flushing a dry gas through the box. 576 flowmeters devices will be installed to monitor the gas flow continuously. A Condensation Prevention System (CPS) has been introduced as condensation was observed. The CPS powers heating wires installed around the SiPM boxes and the vacuum bellows isolating the cooling lines. The CPS also includes 672 temperature sensors to monitor that all parts are warmer than the cavern dew point. The temperature readout systems are based on multiplexing technology at the in the front-end and a PLC in the back-end.

NTUA, Athens, Greece

The present ATLAS Small Wheel Muon detector will be replaced with a New Small Wheel(NSW) detector in order to cope up with the future LHC runs of high luminosity. One crucial part of the integration procedure concerns the validation of the electronics for a system with more than 2.1 M electronic channels. The readout chain is based on optical link technology connecting the backend to the front-end electronics via the FELIX, which is a newly developed system that will serve as the next generation readout driver for ATLAS. For the configuration, calibration and monitoring path the various electronics boards are supplied with the GBT-SCA ASIC and its purpose is to distribute control and monitoring signals to the electronics. Due to its complexity, NSW electronics requires the development of a sophisticated Control System. The use of such a system is necessary to allow the electronics to function consistently, safely and as a seamless interface to all sub-detectors and the technical infrastructure of the experiment. The central system handles the transition between the probe’s possible operating states while ensuring continuous monitoring and archiving of the system’s operating parameters.

Advancements in X-ray detector technology are increasing the amount of volumetric data available for material analysis in synchrotron light sources. Such developments are driving the creation of novel solutions to visualize large datasets both during and after image acquisition. Towards this end, we have devised a library called RemoteVis to visualize large volumes remotely in HPC nodes, using NVIDIA IndeX as the rendering backend. RemoteVis relies on RDMA-based data transfer to move large volumes from local HPC servers, possibly connected to X-ray detectors, to remote dedicated nodes containing multiple GPUs for distributed volume rendering. RemoteVis then injects the transferred data into IndeX for rendering. IndeX is a scalable software capable of using multiple nodes and GPUs to render large volumes in full resolution. As such, we have coupled RemoteVis with slurm to dynamically schedule one or multiple HPC nodes to render any given dataset. RemoteVis was written in C/C++ and Python, providing an efficient API that requires only two functions to 1) start remote IndeX instances and 2) render regular volumes and point-cloud (diffraction) data on the web browser/Jupyter client.

Robot manipulators are an important component in most autonomous systems in the industry. Arc welding, machine tending, painting, picking, are only some examples where the robot manipulators are widely employed. In Synchrotrons some process can benefit from robotic approaches in order to improve automation. Automatic Sample Changer on beamlines is the most common example of automation. This paper describes two robotic applications developed at Synchrotron SOLEIL. Both applications use the SOLEIL robotic standard introduced some years ago [1]. The first application aims to automate the exchange of samples for powder diffraction experiment on the CRISTAL beamline. Hence, a pick-and-place robot is used to automate the process of picking up the sample holders and placing them on the goniometer. The second application, also of the pick-and-place type, is dedicated to the automation of the magnetic characterization of magnet modules of an U15 undulator. These modules, built with a permanent magnet and two poles, are measured using a pulsed wire method [2]. In this case, the robot picks the modules stored in boxes to then place them on the test bench of the U15 undulator.

The modernization plan for the experimental DAQ at the BESSY II is underpinned by the capabilities provided by the Bluesky software ecosystem. To interface with the hardware Bluesky relies on the Ophyd library, that provides a consistent high-level interface across a wide-range of devices. Many elements of the accelerator, some beamlines and endstations are adopting the Bluesky software. To meet FAIR data obligations, the capture of metadata with Bluesky and the export into a permanent and easily accessible storage called ICAT are investigated. Finally, initial studies to investigate the integration of ML methods, like reinforcement learning were performed. This paper reports on the work that has been done so far at BESSY II to adopt Bluesky, problems that have been overcome and lessons learned.

At beamline end-stations, data taking that relies on traditional step scanning, in which motors are repeatedly started and stopped, leads to inefficient usage of the x-ray source. This also increases the risk of sample radiation damage. We have developed a system where scans are performed while continuously moving the motors. To ensure stable repeatable measurements, the detector triggers are generated, in hardware, from the motor encoder positions. Before the scan starts, a list of positions is generated and as the scan progresses a trigger is produced as each successive position in the list is reached. The encoder signals from the motors are connected both to the IcePAP motion controller for closed loop operation, and a PandABox which is used as the trigger source. Control is from Tango and Sardana with a TriggerGate controller that calculates the motor positions and configures the PandABox. The scanned motor can be either a single motor, for example a sample positioner, or a combined motion like a monochromator. When combined motions are required, these make use of the parametric trajectory mode of the IcePAP. This enables continuous scans of coupled axes with non-linear paths.
