Today's high-precision accelerators with arrival time stabilities in the sub-fs range require a very low-noise and long-term stable source as the main oscillator. Due to the different locking bandwidths of the various subsystems,...
Improving the temporal structure of slowly extracted beams (spills) is a key challenge for efficient beam operation at the SIS18 synchrotron of GSI.
This contribution focusses on the recently developed spill optimization system implemented with software-defined radio (SDR) technology. It comprises a feedback system to control the spill rate and an optimization algorithm to automatically...
This poster reports on the improvements in the ChimeraTK frameworks since last year's ARD ST3 workshop.
We will present the new Tango support feature, which completes the set of mainstream control system middleware supported by ApplicationCore-based device servers.
Integrating our software stack into the Yocto embedded Linux ecosystem enables us to run directly on SoCs with current and...
Motivated by the overarching goal of designing a unifying controller for continuous wave operation that integrates piezo and RF control for stabilizing amplitude and phase of a cavity field with active microphonics suppression , we conducted measurements on a cryo module with piezo signal as input and cavity gradient as output to establish a linear model that could be used for model-based...
One of the key metrics determining the capabilities of Free Electron Laser (FEL) facilities is the intensity of photon beam they can provide to experiments. However, in day-to-day operations, tuning to maximise the FEL intensity is one of the most difficult and time-consuming tasks. Skilled human operators still need large amounts of the available beam time, which are then not available for...
Autonomous tuning of particle accelerators is an active and challenging field of research with the goals of reducing tuning times and enabling novel accelerator technologies for novel applications. Large language models (LLMs) have recently made enormous strides towards the goal of general intelligence, demonstrating that they are capable of solving complex task based just a natural language...
FLUTE (Ferninfrarot Linac Und Test Experiment) is a new compact versatile linear accelerator at KIT. Its main goal is to serve as a platform for a variety of accelerator studies as well as a generation of strong ultra-short THz pulses for photon science. Also it will be used as an injector for a Very Large Acceptance compact Storage Ring (VLA-cSR) which will be realized at KIT in the framework...
The Turkish Accelerator and Radiation Laboratory in Ankara (TARLA) is Turkeys first particle accelerator research facility. DESY provides TARLA with a MicroTCA.4-based LLRF control system. This system was assembled and tested at DESY and shipped to TARLA. It was commissioned earlier this year and saw first beam. Find in this contribution a more detailed description of the LLRF system as well...
Many components, including software/hardware CPUs, hardware description language (HDL) modules, high-level synthesis (HLS) entities, and embedded Linux / bare-metal applications, are used in the development of modern FPGA firmware. This is due to the usage of custom modules, tools from various vendors, and hierarchical designs from various manufacturers. The mentioned process is initially...
Future high duty cycle operation scenarios of the European X-ray Free Electron Laser (EuXFEL) promise increased bunch repetition rate and photon delivery, at the cost of changing system requirements and moving away from the proven mode of short pulse operation. To assess the applicability of the currently installed 3rd harmonic cryomodule, key parameters of its spare sibling installed at the...
While the arrival time stability of electron bunches in a free-electron laser (FEL) can be as precise as 5 fs rms, the arrival time jitter of optical laser pulses is around 10 fs rms or worse at the experimental setups. In this contribution, we will provide an update on a laser pulse arrival time monitor, where the arrival time of optical pulses will be measured against an optical reference...
Precisely calibrating RF superconducting radio-frequency linear accelerators is crucial for accurately assessing cavity bandwidth and detuning, which provides valuable insights into cavity performance, facilitates optimal accelerator operation, and enables effective fault detection and diagnosis. In practice, however, calibration of RF signals can present several challenges, with calibration...
Today's high-precision accelerators with arrival time stabilities in the sub-fs range require a very low-noise and long-term stable source as the main oscillator. Due to the different locking bandwidths of the various subsystems, sources with low phase noise down to below -175dBc/Hz are required for arrival times below 1fs. In order to connect laser systems and optical low-latency links...
PETRA IV, a low emittance fourth generation light source is the upcoming flagship project of DESY. Stringent stability of the electron beam orbit in the ring will be required to achieve a diffraction limited photon beam quality. A fast orbit feedback system is being modelling and designed. One important aspect is the disturbance modelling. Preliminary ideas for correlation lengths of ground...
