Shreeharshini Dharanesh Murthy (Lawrence Berkeley National Laboratory)10/14/25, 2:10 PMPoster
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...

Mr James Latshaw (JSA)10/14/25, 2:10 PMPoster
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...

Mr James Latshaw (JSA)10/14/25, 2:10 PMPoster
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...

Paula Van Rooy (Los Alamos National Laboratory)10/14/25, 2:10 PMPoster
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...

One easily overlooked component of Low-Level Radio Frequency (LLRF) design is the commissioning of new system installations. During Jefferson Lab’s (JLab) 2024 Scheduled Accelerator Maintenance (SAM), two CEBAF zones were upgraded with C75 Cryomodules and JLab’s LLRF 3.0 system. JLab’s team has invested heavily in the automation and standardization of their commissioning process. Several...

In the Hard X-ray Free Electron Laser (SHINE), the normal-conducting L-band buncher is critical for compressing electron bunches, significantly improving beam quality to meet stringent low-emittance and low-energy-spread injection requirements. Due to its 2-cell structure, a digital LLRF control system which based on an FPGA and RF front-end architecture using I/Q demodulation was designed....

Joshua Settle (Jefferson Lab)10/14/25, 2:10 PMPoster
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...

Maciej Grzegrzółka (Warsaw University of Technology, Institute of Electronic Systems)10/14/25, 2:10 PMPoster
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...

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...
