  The ELSA facility utilizes several digital cameras for beam profile measurements on luminous screens and synchrotron radiation monitors. Currently a multitude of devices with analog signal output are being replaced in favor of digital outputs, preferably with data transfer via Ethernet. The increased network traffic for streaming, analyzing, and distribution of processed data to control system and machine operators is managed through a supplementary camera network in which distributed computing is performed by the RabbitMQ message broker. This allows performant and platform-independent image acquisition from multiple cameras, real time profile analysis, and supports programming interfaces for C++ and Python. The setup and performance of the implementation are presented.

MOP39 Development of Compact Radio Frequency Sources controls, ECR, radio-frequency, Ethernet 144

Our group is developing a family of compact radio frequency sources aiming to cover 50 MHz to 20 GHz with several models. The primary goal is to provide an alternative to using expensive laboratory generators in permanent installations. In addition, we work towards providing a higher specification than similar telecommunications devices as this is a typical requirement in accelerator instrumentation. We take a minimalistic approach with only a network interface planned, assuming that such a device operates remotely in a large facility. An EPICS interface is in the works for monitoring and control. In this paper, we present the results of rapid prototyping with XMicrowave components. The first measurements show encouraging phase noise performance and spectral purity.

  The Synchronous Data Service (SDS) is a tool to monitor and capture events in the European Spallation Source, building on top of the EPICS control system. Large amounts of data from different input output controllers are acquired and synchronised at the level of beam pulses. The acquisition can be triggered by beam events though the timing system or manually by a user. Captured data is stored in standardised NeXus files and indexed in a database for easy searching and retrieval.

  Modern particle accelerator facilities allow new and exciting beam properties and operation modes. Traditional real-time control systems, albeit powerful, have bandwidth and latency constraints that limit the range of operating conditions currently made available to users. The capability of Reinforcement Learning to perform self-learning control policies by interacting with the accelerator is intriguing. The extreme dynamic conditions require fast real-time feedback throughout the whole control loop from the diagnostic, with novel and intelligent detector systems, all the way to the interaction with the accelerator components. In this contribution, the novel KINGFISHER framework based on the modern Xilinx Versal devices will be presented. Versal combines several computational engines, specifically combining powerful FPGA logic with programmable AI Engines in a single device. Furthermore, this system can be natively integrated with the fastest beam diagnostic tools already available, i.e. KAPTURE and KALYPSO.

TUP42 Fast Orbit Feedback Upgrade at SOLEIL network, FPGA, controls, electron 339
  • R. Broucquart, N. Hubert
    SOLEIL, Gif-sur-Yvette, France
  In the framework of the SOLEIL II project, the diagnostics group must anticipate ahead of the dark period the upgrade of important system like the BPM electronics, the timing system end the Fast Orbit Feedback (FOFB). The FOFB is a complex system that is currently embedded in the BPM electronics modules (eBPM). A new flexible stand-alone platform is under conception to follow the future upgrades of surrounding equipment, and to allow the integration of future correction schemes. In this paper we will present the current status of technical decisions, tests and developments.

WEP04 Dual channel FMC High-Voltage Supply high-voltage, controls, detector, power-supply 383
  • W. Viganò, J. Emery, M. Saccani
    CERN, Meyrin, Switzerland
  The Beam Loss Monitoring (BLM) detectors and electronics are installed along the CERN accelerators to provide measurements of the beam loss as well as protection from them when excessive. Majority of the BLM detector types require voltage biasing up to 2000VDC with the possibility to generate voltage modulation patterns to verify the connection chain of the detectors to the front-ends. Currently, the power supply solution consists of COTS large format power supplies with additional custom electronics and various interconnections to provide monitoring and remote control. For this reason, a market search has been done to identify a high reliability module suitable for dedicated BLM installations composed by a few detectors. The outcome of the market search has justified the need to design a low cost custom board, compatible with the CERN infrastructure and different detector types, as well as allow easy customization to cover various installation architectures and voltage range needs. Main characteristics could be summarized with the following points: completely remote controlled and autonomous system, common hardware for different applications, only need to change DC\DC converter.
Other characteristics: few more components for different application and make a model smaller than what is currently used as high voltage power supplies.

  The SINBAD(Short and INnovative Bunches and Accelerators at DESY ) R&D accelerator is planned for studying new concepts for high gradient electron beam acceleration and the generation of ultra-short electron bunches. The accelerator called ARES(Accelerator Research Experiment At DESY) is composed of S-band accelerating structures. In order to achieve the goal of very short electron bunches the electron beam charges generated in the RF Gun can vary in a range from 1nC down to 500fC. In order to measure the beam position with good resolution at the small charge end of 500fC a new cavity BPM(beam position monitor) has been developed. One key component in the BPM system is the custom RF electronics to meet the resolution requirements in the entire charge range. The entire BPM system with a focus on the system design requirements and the utca based RF electronics are presented in this paper.
