  The ESRF-Extremely Brilliant Source (ESRF-EBS)* is the first-of-a-kind fourth-generation high-energy synchrotron. After only a 20-month shutdown, scientific users were back to carry out experiments with the new source. The EBS Simulator (EBSS) played a major role in the success of the commissioning of the new storage ring. Acting as a development, sandbox and training platform, the machine simulator allowed control room applications and tools to be up and ready from day one. The EBSS can also be seen as the initial block of a storage ring digital twin. The present article provides an overview of the current status of the EBS Simulator and presents the current roadmap foreseen for its future.

  The new Accelerator Control System for GSI/FAIR is now being used productively for the GSI accelerator facility. As the central component for online beam orchestration, the Beam Scheduling System (BSS) is situated between the FAIR Settings Management System and the FAIR timing system. Besides device settings, the Settings Management System provides timing schedules for beam production. The primary purpose of the BSS is to define which of the beam schedules are executed by the timing system, how often and in which order. To provide runtime decisions in pre-planned execution options (e.g. skipping of a particular beam), it processes external signals like user input, experiment requests or beam prohibits provided by the interlock system. More recently, advanced features have been added that allow for dynamic execution control required by storage ring mode features such as breakpoints, repetitions, skipping and manipulations. This contribution gives an overview of the Beam Scheduling System including its interfaces.

  NewSUBARU has constructed a new dedicated injector in order to separate the operation from SPring-8 and to operate independently. In designing this injector, we tried to share the same components as those of the Tohoku Synchrotron Radiation Facility, which will be completed in 2023, in order to make effective use of human resources. The control system of the injector and the existing storage ring must be constructed as unified system, so the file server, DB server, backbone network, etc. were redesigned using the control system used in SPring-8/SACLA as a control framework. MTCA.4 was used to control the injector, and EtherCAT was used to communicate with the PLC. For the control of the storage ring, the existing equipment configuration was retained and the control framework was migrated. In this paper, we report the details of the NewSUBARU control system.

WEPV007 Machine Learning Projects at the 1.5-GeV Synchroton Light Source DELTA controls, injection, synchrotron, electron 631

  In recent years, several machine learning (ML) based projects have been developed to support automated monitoring and operation of the DELTA electron storage ring facility. This includes self-regulating global and local orbit correction of the stored electron beam, betatron tune feedback as well as electron transfer rate (injection) optimization. Furthermore, the implementation for a ML-based chromaticity control is currently prepared. Some of these processes were initially simulated and then successfully transferred to real machine operation. This report provides an overview of the current status of these projects.

WEPV011 Research on Correction of Beam Beta Function of HLS-II Storage Ring Based on Deep Learning network, quadrupole, controls, feedback 645

  The beam stability of the storage ring determines the light quality of synchrotron radiation. The beam stability of the storage ring will be affected by many factors ’such as magnetic field error, installation error, foundation vibration, temperature variation, etc., so it is inevitable to correct the beam optical parameters to improve the beam stability. In this paper, the deep learning technology is used to establish the HLS-II storage ring beam stability model, and the beam optical parameters can be corrected based on the model. The simulation results show that this method realizes the simulation correction of the Beta function of the HLS-II storage ring, and the correction accuracy precision meets the design requirements.

WEPV047 Supporting Flexible Runtime Control and Storage Ring Operation with the FAIR Settings Management System controls, timing, operation, experiment 768

  The FAIR Settings Management system has now been used productively for the GSI accelerator facility operating synchrotrons, storage rings, and transfer lines. The system’s core is being developed in a collaboration with CERN, and is based on CERN’s LHC Software Architecture (LSA) framework. At GSI, 2018 was dedicated to integrating the Beam Scheduling System BSS. Major implementations for storage rings were performed in 2019, while 2020 the main focus was on optimizing the performance of the overall control system. Integrating with the BSS allows us to configure the beam execution directly from the settings management system. Defining signals and conditions enables us to control the runtime behavior of the machine. The storage ring mode supports flexible operation with features allowing to pause the machine and execute in-cycle modifications, using concepts like breakpoints, repetitions, skipping, and manipulation. After providing these major new features and their successful productive use, the focus was shifted on optimizing their performance. The performance was analyzed and improved based on real-word scenarios defined by operations and machine experts.
