The rapid advancement of Radio Frequency System-on-Chip (RFSoC) technology from Xilinx (AMD) has enabled the integration of high-speed data converters and programmable logic within a single package. RFSoC platforms are already widely adopted in telecommunications, radar, and satellite communications, where they promise reductions in system footprint and power consumption. However, their...
The EIC Common Platform is a modular system architecture which will serve as the basis for EIC Accelerator Controls. It consists of an SoC-based carrier board with up to two independent pluggable FPGA-based Daughtercards. Different types of Daughtercards have custom electronics catering to the specific needs of an application. Daughtercards will have FPGA logic to support a common protocol for...
The TEX (Test-stand for X-band) facility at LNF-INFN was established in 2021 and commissioned in 2022. It serves as an R&D center for X-band technology, supporting activities from waveguide component design and high-power testing to low-level RF (LLRF) system development. TEX is equipped with a 50 MW X-band klystron (CPI, USA) powered by a K400 solid-state modulator (ScandiNova, Sweden),...
The Electron Ion Collider project is a large and exciting effort within the accelerator community. There will be 8 different styles of Cryomodule and as many varied styles of normal conducting cavities. All of these modules require interlock protection and most require some form of resonance control. This abstract presents the ongoing efforts at Jefferson Lab to develop a modular system which...
At the LLRF 2023 conference, Jefferson Lab’s Fast DAQ for Machine Learning was shared. This system equips the legacy CAMAC zones with a digital fast data acquisition system which samples and reports at a rate of 5 kHz to allow for detection of transients that operators would be otherwise blind to. This equips the legacy zones with both real time waveforms of key cavity control signals as well...
The Los Alamos Neutron Science Center (LANSCE) Accelerator is in the initial planning stages to upgrade the front-end of LANSCE, a project known as the Los Alamos Modernization Project (LAMP). As a part of this upgrade the Low-Level Radio Frequency (LLRF) team will be replacing most of their equipment. This involves removing and installing new equipment related to the sources, injectors, low...
The Proton Synchrotron (PS), CERN’s first synchrotron, delivers proton and ion beams with intensities covering almost four orders of magnitude using 25 RF cavities with frequencies ranging from 0.4 to 200 MHz. The LLRF system includes multi-harmonic feedback loops to control the field in the cavities and beam-based loops to perform complex beam manipulations. The current beam control system is...
In collaboration with the Berkeley Accelerator Controls and Instrumentation Program, the Argonne Wakefield Accelerator Facility successfully completed an upgrade of its Low-Level Radio Frequency (LLRF) system using the LCLS-II LLRF platform. This poster will present the details of the upgrade.
The Electron Ion Collider is an exciting collaborative effort to advance and invest in the future of nuclear physics and accelerator science. Part of this great effort includes designing a diverse set of RF cavities and control systems, in which heterodyning still plays a fundamental role. There are multiple frequencies in the VHF and UHF bands which require up and/or down conversion, and...
The European Spallation Source (ESS) beam instrumentation generates over 100 gigabytes of data per second from over 100 subsystems along the whole ESS linac. Currently, the data is only processed locally. The development of machine learning techniques and hardware created an opportunity to allow complex analysis of the data coming from the whole accelerator. Such analysis can bring benefits to...
The Linac Electronics Modernization Plan (LEMP) replaces the aging CAMAC-based low-level RF (LLRF) controls in SLAC’s normal-conducting LINAC. The new system is based on the open-source Marble FPGA carrier and Zest+ digitizer, with a custom RF front end. A prototype has been deployed and tested at station 26-3, demonstrating key functionality including RF control, interlocks, and waveform...
Covering topics such as temperature-dependent capacitance of piezo actuators, fast tuner range and polarity determination, Lorentz force detuning coefficient, cavity mechanical response and π-mode detection, through to real-time firmware-based cavity parameter identification, fast and slow quench detection, and more, LUT-DMCS has developed and validated a comprehensive set of firmware and...
The PAL-XFEL LLRF and SSA systems have contributed to the stable operation of PAL-XFEL for nearly a decade with their reliability and robustness. Key achievements of these systems include the development of pulse-by-pulse real-time RF switching function for simultaneous operation of the HX and SX beamlines, development of a converter-type X-band LLRF, and development of a function to improve...
The SHINE injector consists of an electron gun, a bunching cavity, a single-cavity cryo-module, and an 8-9 cell cryo-module. It has now completed commissioning, with an output energy of 100 MeV and an energy jitter of 0.003% (RMS). The amplitude and phase control accuracy of all RF acceleration structures have met the design specifications.
The PIP-II linac is an international collaboration project with in kind contributions of key subsystems from multiple countires including India(DAE). In the research and development phase of the project, the LLRF and resonance control systems were jointly developed by BARC and Fermilab and were delivered to Fermilab for testing and validation. Initial testing of the LLRF system was carried...
The Electron-Ion Collider (EIC) is a long-term project to design and construct a facility to collide high energy polarized electron beams with polarized proton and heavy ion beams at center of mass energies from 20 to 140 GeV with luminosity up to 1034 cm-2s-1. This facility will be built on top of the Relativistic Heavy Ion Collider (RHIC), Brookhaven National Laboratory’s current operational...
Ranging from detecting a slow temperature rise to responding rapidly to
excessive current flow in the coupler bias high-voltage circuit, and up
to detecting stray RF signals, the Radio Frequency Protection Interlock
(RFPI) system is designed to monitor numerous cavity-related signals and
react within 100 µs - 1ms time to any observed violation of safety
margins. This contribution...
The warm front end for the PIP-II linac consists of an Ion-source an RFQ and four buncher cavities. The LLRF systems for these were the first ones developed more than a decade ago for use at the test stands. Some were VXI crate based and others used early generation FPGA boards that are light in resources. These LLRF systems and the one for the first superconducting cryomodule, the HWR will be...
