1:15 PM - 2:05 PM
The Crab Cavity Low-Level RF systems in hadron machines will have to reduce the Crab Cavity impedance to prevent transverse instabilities, while regulating the crabbing voltage and minimizing the Radio Frequency noise levels injected to the beam. These are challenging and partly conflicting requirements. In this talk, I will summarize the studies that set the Crab Cavity LLRF specifications and guide the design. I will also present possible trade-offs in the architecture and identify the major challenges as these systems are designed, built, and commissioned.

2:05 PM - 2:35 PM
Magnetic alloy (MA) cavities have wideband frequency responses, which allow multiharmonic rf voltage excitation in a single cavity. In the low level rf (LLRF) control system for the Japan Proton Accelerator Research Complex (J-PARC) Rapid Cycling Synchrotron (RCS) the multiharmonic vector rf voltage control feedback is implemented to realize the dual harmonic rf operation for bunch shaping and to compensate of the multiharmonic beam loading. The multiharmonic feedback consists of several classical IQ feedback blocks, and the RCS system has eight feedback blocks. Similar feedback systems are employed for the other proton synchrotrons, such as CERN PSB and CSNS. The possible application of multiharmonic feedback is not limited to bunch shaping using dual harmonic. Using triple harmonic operation, we can generate more flat rf buckets for realization of flatter bunches. Ultimately, barrier buckets can be generated using many harmonics. Other interesting application is generating a non-integer harmonic rf with several harmonics, which can be used for butch compression. In the presentation, we will explore these possible applications. We will also discuss important considerations when using multiharmonic feedback. One must be careful about the frequency response of the cavity voltage monitor to adjust the precise harmonic voltages. Another point is that unwanted cavity voltage jump may happen after fast extraction of a high intensity beam.

A high-performance low-level radio frequency (LLRF) control system based on ZYNQ MPsoc has been developed to enable the digital and intelligent upgrade of Shanghai Soft X-ray Free-Electron Laser (SXFEL). It includes 8 channels of 310 MSPS 16-bit ADCs and 2 channels of 500 MSPS 16-bit DACs, capable of outputting continuous wave and pulse wave signals, respectively. The LLRF control system is equipped with an FMC(LPC) interface to communicate with the White Rabbit(WR) device in the control system, providing feedback on the SXFEL' s orbit, focusing, and beam energy states. In experimental measurements on SXFEL, the LLRF system achieves a amplitude stability of 0.016% (RMS) and a phase stability of 0.015o at pulse compressor output.

2:55 PM - 3:15 PM
CERN's planned Future Circular electron-positron collider (FCC-ee) must accommodate very different RF system requirements at different energy points, driven by a fixed synchrotron radiation power budget of 100 MW. Recently, a unified RF cavity design with constant loaded quality factor suitable for three beam energies (45.6, 80, and 120 GeV) was adopted as the baseline. The new RF system implementation requires the inclusion of the reverse phase operation (RPO) scheme for the Z operating point (45.6 GeV). In this contribution, the main principles of the RPO scheme are first explained. The need to mitigate the enhancement of transient beam loading due to the RPO scheme is described, along with the corresponding LLRF and HLRF requirements to achieve precise control of the cavity field. Finally, the dynamics of the beam and RF system in the event of RF system failures are analyzed, including a detailed implementation of LLRF loops and interlocks.

3:15 PM - 3:35 PM
Brookhaven National Laboratory (BNL) is the future home of Electron-Ion Collider (EIC) project that will be constructed in partnership with Thomas Jefferson National Accelerator Facility (Jefferson Lab, JLAB). The EIC proposal provides a design that utilizes the existing RHIC facility to produce hadron beams, including high-intensity polarized proton beams, to fully meet the requirements for a lasting research program with high potential for new discoveries. It is also planned as a cost-effective new facility with approximately 30 SRF cryomodules and 55 NCRF cavities that includes reuse of RHIC 28 MHz and 197 MHz cavities. Many systems are still developing but plenty of progress has been made on EIC RF Systems since it was last presented at LLRF Workshop 2022. The scope of the RF systems as currently defined at pre-construction design phase of the EIC project will be presented.

4:35 PM - 5:05 PM
ALBA Low-Level RF (LLRF) system has provided over a decade reliable operation and has been adopted by other synchrotron facilities. To meet the evolving requirements of ALBA and ALBA-II, a new LLRF system has been developed for the current fundamental RF system and the future active normal conducting harmonic RF system. This new LLRF features FPGA and ADC/DAC µTCA boards designed by Safran, enabling direct 500 MHz signal sampling without down/up-conversion for the main RF system, while it requires an intermediate frequency in the case of the harmonic system performed in the RTM board itself. These enhancements reduce system complexity, minimize noise, and simplify maintenance. Safran also supplies peripheral modules and the Tango device server generator, while ALBA implemented it and developed a new GUI. Upgraded Digital and RF signal front-ends complement the new hardware. The legacy VHDL code has been updated to improve readability and functionality, incorporating advanced features such as octant selection and a harmonic direct feedback selection method. The latter, based on IIR filtering, isolates positive and negative revolution harmonics in the I/Q domain, feeding them back to amplifiers to effectively mitigate transient beam loading caused by the storage ring bunch train gaps. This upgraded LLRF system delivers enhanced performance and greater flexibility to address the future needs of ALBA and ALBA-II.

5:05 PM - 5:25 PM
The SPARC_LAB facility at LNF includes a high-brightness electron linac dedicated to plasma acceleration studies and R&D. Given the stringent stability requirements on electromagnetic fields, especially for particle-driven plasma acceleration, several upgrades have been implemented over the past two years to enhance RF stability and measurement accuracy. In 2024, the low-level RF system was completely refurbished, replacing the original analog systems with digital ones featuring temperature-stabilized front ends and arbitrary pulse shaping capabilities. Additionally, the intra-pulse phase feedback, originally commissioned in 2008 for the S-band klystrons, was upgraded. A new RF design, along with improved error amplifiers and signal acquisition electronics, was deployed and first tested on the machine in Fall 2024. Comprehensive short- and long-term measurements performed at SPARC_LAB confirm the system's ability to reliably and reproducibly reduce S-band klystron phase jitter down to 15 fs rms. The obtained results are now very close to the 10 fs limit demanded by plasma acceleration and represent a promising step toward meeting the requirements of future accelerator facilities.

SPARC_LAB is a high-brightness e-beam for SASE-FEL (self-amplified spontaneous emission-FEL) experiments. It consists of a brazeless 1.6-cell S-band RF gun, two travelling wave S-band accelerating structures each 3 meters long, and a 1.4-meter C-band structure that acts as an energy booster. As part of the SABINA project, co-funded by the Lazio Regional Government for consolidation of SPARC_LAB, a significant upgrade of the RF control systems was completed last year. The activity involved the development of software for remote control of LLRF systems, C-band modulator, as well as custom hardware made by the RF service for fast feedbacks and RF synchronization. Algorithms were also developed for statistical and diagnostic analysis of RF signals, with real-time amplitude and phase jitter monitoring capabilities. Development of a custom EPICS application aimed at optimizing system resources is currently underway. Finally, to support conditioning operations, dedicated software has been implemented for automatic RF plant management, which dynamically adjusts RF power and manages interlocks under critical conditions.

9:25 AM - 9:45 AM
The SEL architecture used commonly in CW superconducting linacs is a positive feedback system that requires determining the correct limits for the operating conditions to ensure stable operation. These limits are determined from the results of the amplifier calibration which characterizes the dac drive(forward power) against the cavity field. When the amplifier non-linearity precludes a simple linear fit for this characteristic, its modification to account for the amplifiers non-linearity is essential to operate the system in the SEL architecture. This process is described with test data from a 32kW SSA for the PIP-II linac.

9:45 AM - 10:05 AM
Various digital low-level radiofrequency (LLRF) systems are now operating for the Advanced Photon Source Upgrade (APS-U). This includes a passive superconducting bunch-lengthening cavity LLRF system primarily used for quench detection and signal monitoring of both the cavity and beam. The original analog-based LLRF systems for the klystron-driven main accelerating cavities were kept intact. However, a digital 60-Hz-harmonic-related rf noise suppression (RFNS) system was added to suppress noise from the megawatt-class klystrons which leads to beam motion. Additionally, within the injectors, the Particle Accumulator Ring was upgraded to digital LLRF for improved control. This report summarizes the systems and shares operational experience with beam. * Work supported by U. S. Department of Energy, Office of Science, under Contract No. DE-AC02-06CH11357

The Facility for Rare Isotope Beams (FRIB) was fully commissioned in 2021 and began user operations in May 2022. This talk provides an update on Low-Level Radio Frequency (LLRF) system activities at FRIB during the transition from commissioning to routine operation. Key efforts have focused on spare parts management and the development of advanced troubleshooting tools to support reliable system performance. We present operational insights from the early stages, including achieved performance metrics, system uptime, lessons learned, automation of cavity turn-on/off, conditioning, auto-restart process and beam based feedback for LLRF energy and phase regulation. Additionally, we briefly introduce ongoing developments of a new LLRF hardware platform designed to support future FRIB upgrade cavities. This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics and used resources of the Facility for Rare Isotope Beams Operations, which is a DOE Office of Science User Facility under Award Number DE-SC0023633.

10:50 AM - 11:10 AM
PIP-II is a superconducting linac that is in the initial acceleration chain for the Fermilab accelerator complex. The RF system consists of a warm front-end with an RFQ and buncher cavities along with 25 superconducting cryo-modules comprised of cavities with five different acceleration β. The LLRF system for the linac has to provide field and resonance control for a total of 125 RF cavities. Various components of the LLRF system have been tested with and without beam at the PIP-II test stands. The LLRF system design is derived from the LCLS-II project with its self-excited loop architecture used in the majority of the cryo-modules. The PIP-II beam loading at 2 mA is much higher than LCLS-II linac. The control system architecture is analyzed and evaluated for the operational limits of feedback gains and their ability to meet the project regulation requirements for cavity field amplitude and phase regulation.

The 3 ms long RF pulse at ESS will make Lorentz force detuning (LFD) significant for the superconductive cavities and at 14 Hz repetition rate some ringing might still be present at the start of the next pulse. An iterative compensation algorithm have been developed to reduce the required overhead to maintain a constant cavity field. It is based on detuning calculation of each pulse and provides a voltage to the Piezo stack to counteract LFD. Design details and initial results will be presented.

As the use of SRF cavities continuously increases at CERN, testing facilities are also being upgraded. Due to the variety of operating frequencies, ranging from 400 MHz to 1.3 GHz, a generic cavity controller has been designed implementing Generator Driven (GD) and Self-Excited Loop (SEL) modes. A modern approach for separating gateware, embedded firmware (micro-controller unit) and low-level software, as well as Continuous Integration (CI) for automatic bitstream generation and simulation have been used in the Universal Cavity Controller (UCC). Additionally, the UCC development is planned to be applied in MicroTCA architecture in the framework of a project for axion detection using a SRF cavity.

11:50 AM - 12:10 PM
With the talk, we present recent developments of the high-power microwave components with their applications for SRF accelerators. The first example is the Ferroelectric Fast Reactive Tuner (FE-FRT) developed by Euclid in collaboration with FNAL and BNL, and successfully tested at CERN. This technique has now become practically feasible due to the recent development of a new extremely low loss and fast (10 ns-100 ns time range) ferroelectric material, which has been tested, and fast frequency tuning has been demonstrated. The Horizon Europe iSAS project focuses on improving accelerator efficiency and includes the integration of a ferroelectric fast reactive tuner (FE-FRT) to enhance energy conservation. Applications under this initiative include transient beam loading and microphonic compensation. In the U.S., FE-FRT technology is under active development for microphonics compensation in CEBAF by the DOE SBIR 2025 project. In the initial part of the project, an RF model of a 3-stub tuner with the ferroelectric section are being fabricated to be tested at Jlab. Control System and LLRF model of integration of the ferroelectric based three-stub tuner into the CEBAF cryomodule is under development.

1:20 PM - 2:10 PM
Amplifier Additive Phase Modulation (APM) noise performance is a critical and often overlooked parameter which may significantly impact the signal integrity of Communication, RADAR, EW, Synthesizer, Frequency Converter, and related equipment. This tutorial will address APM noise test equipment capabilities and limitations and will provide a detailed description of Mini-Circuits’ Device Under Test (DUT) characterization procedures and methodologies. A theoretical discussion of white and flicker noise processes in amplifiers and their impact on APM noise performance in both small and larger signal regions of operation will be presented. The tutorial will further demonstrate that AM-to-PM distortion, another often unspecified amplifier parameter, may significantly degrade APM noise performance in both the White and Flicker noise regions when operating near or above the amplifiers 1 dB compression point. Active device technologies and different amplifier topologies are discussed and measured data supporting the results are presented.

The digital low level RF systems that are used to operate 17 of the 53 cryomodules that are installed in CEBAF have the capability to log 17 waveforms either on demand or when one of the cavities in the cryomodules trips off. In 2018, the software and hardware in the digital low-level RF systems was configured such that a fault would trigger an acquisition process to record 17 RF waveform signals for each of the 8 cavities within the cryomodule for subsequent analysis. To date approximately 15,000 faults have been analyzed. This contribution will describe the types of faults encountered during operation and their signatures in the time domain data, as well as how it is being used to modify the setup of the machine and implement improvements to the cryomodules.

Superconducting RF crab cavities will be implemented in the upcoming High-Luminosity LHC upgrade to compensate the luminosity loss due to a large crossing angle at the interactions points. In order to be beneficial for luminosity, the crab cavity system must have extremely good RF noise performance, else the emittance blow-up from its own noise may further degrade the luminosity. Required noise performance of the Low-level RF and High-power RF systems is beyond the limit of what is possible with current technology. An active "noise feedback" in the LLRF system was therefore proposed to help mitigate the emittance growth from the crab cavity system. We present the challenges of very demanding noise feedback LLRF system design, proposed processing algorithms and preliminary results from the proof of concept testing phase. The challenge is not only the ultra low noise digitizer with large bandwidth and low ENOB converters, but also implementing a high performance, strictly beam synchronous bunch by bunch measurement into an asynchronous, fixed clock LLRF system.

The Electron-Ion Collider (EIC) will operate with a 25 mrad crossing angle at the interaction points to enable rapid beam separation, reduce detrimental beam-beam effects, and provide space for forward detectors. This crossing geometry, however, significantly reduces the overlap region of the colliding bunches, resulting in nearly an order of magnitude luminosity loss. To restore effective head-on collisions and achieve maximum luminosity, crab cavities will apply transverse kicks to each bunch, rotating them in the crossing plane. The success of this scheme depends critically on the performance of the Low-Level RF (LLRF) system, which must deliver high-gain, low-noise field control to suppress transverse emittance growth and maintain beam stability. This presentation will describe the LLRF system architecture and control strategy for the EIC crab cavities, including RF noise mitigation, impedance control, crabbing phase closure, and integration planning. The current hardware development status and the roadmap toward full system implementation will also be presented.

Low-Level RF (LLRF) systems are fundamental to the precise control of accelerating fields in modern particle accelerators, ensuring the required stability in amplitude and phase to achieve consistent beam quality. As accelerator technologies evolve toward higher frequencies and more compact designs, the X-band regime is increasingly adopted due to its support for high-gradient structures and ultra-short RF pulses. However, the shift to X-band introduces greater sensitivity to phase noise, timing jitter, and thermal fluctuations, requiring a new generation of LLRF controllers with faster signal processing and tighter control loops. In this context, a dedicated X-band LLRF prototype has been developed to meet the demanding requirements of the future EuPRAXIA@SPARC_LAB LINAC, as part of the EuPRAXIA Doctoral Network. The prototype integrates a high-speed front-end and back-end system optimized for fast pulse processing and enhanced signal fidelity. It is now prepared for full evaluation on a real accelerator test bench at the TEX facility, INFN-LNF. This paper presents the concept, implementation, and readiness of the prototype system.

A digital LLRF system [1] has been successfully developed and deployed for control of the accelerating Voltages on the Ferrite loaded RF cavities on the ISIS Synchrotron over the last decade. The final stage of the digital control system has recently been completed which now includes digital control of the cavity tuning. Similar National Instruments FPGA modules to those used in the Synchrotron LLRF system have been used to develop a LLRF control system for the RAL Front End Test Stand (FETS) [2] and the ISIS Pre-Injector Test Stand (PITS) [3]. These systems are based on the digital LLRF system developed at the University of the Basque Country [4]. The RF system on FETS comprises of a Radiofrequency Quadrupole (RFQ) and 3 re-bunching cavities operating at 324MHz. That for PITS consists of an RFQ and 4 quarter wave resonator cavities all operating at 202.5MHz and is intended as a pre-cursor to the upgrade of the ISIS Pre-Injector planned for 2027, when the same LLRF control system will also be deployed on the 4 LINAC tanks and de-bunching cavity. Initial tests of the LLRF system have been made on one of the QWR cavities and both RFQs and will be continued as more cavities become available. 1. “Status of the ISIS Synchrotron Digital LLRF System” Seville et al, LLRF 2022. 2. “Status of the RAL Front End Test Stand” Letchford et al, IPAC 2015. 3. “The Pre-Injector Upgrade for the ISIS H− LINAC” Lawrie et al, LINAC 2022. 4. “New PXIe-Based LLRF Architecture and Test Bench for Heavy Ion Linear Acceleration” Badillo et al, IEEE-NPSS Real Time Conference 2014

11:10 AM - 11:30 AM
The CERN Proton Synchrotron (PS) LLRF system is one of the oldest in operation at CERN. To meet the growing demands of high-intensity fixed-target experiments at CERN, a sophisticated beam manipulation technique combining barrier-bucket radiofrequency gymnastics with Multi-Turn Extraction (MTE) has been developed and successfully implemented in the PS. The newly developed system enables cycle to cycle updates off the turn-synchronous voltage waveform applied to the wide-band Finemet cavity. It allows both intra-cycle manipulations and synchronization with respect to the Super Proton Synchrotron (SPS) extraction reference. These features have been fully tested with both the MTE and ion beams, successfully demonstrating synchronous barrier bucket extraction and non-integer harmonic batch compression. This contribution summarizes the upgrades to the Finemet cavity controller, showing the new system architecture and demonstrating its operation with beams in the machine.

With evolution of technology, accelerator RF systems are becoming more and more complex and dense. At the same time, requirements for performance, precision or noise floor are getting increasingly tighter. Electromagnetic compatibility and signal integrity must be part of the design right from the beginning regardless if is it a 1 MW RF amplifier or an FPGA sitting on a 10 layer printed board. In this tutorial, we will recap basic principles of EMC and signal integrity and discuss some of the most popular problems on signal routing, printed boards, decoupling, cables, connectors, grounding, filtering or shielding.

A challenge that industrial particle accelerators face is the high amounts of noise in sensor readings. This noise obscures essential beam diagnostic and operation data, limiting the amount of information that is relayed to machine operators and beam instrumentation engineers. Machine learning-based techniques have shown great promise in isolating noise patterns while preserving high-fidelity signals, enabling more accurate diagnostics and performance tuning. Our work focuses on investigating the challenges associated with the implementation of a noise reduction autoencoder that operates in real time on a Field Programmable Gate Array, which we do by creating firmware to run on a Xilinx ZCU104 evaluation kit with the intention of being deployed on industrial particle accelerators in the near future.

2:30 PM - 2:50 PM
The CERN Proton Synchrotron (PS) is equipped with several RF systems covering a wide range of revolution frequency harmonics. While the beam synchronous RF signal generation and cavity controllers are mostly digital, the global low-level RF beam loops still rely on analogue hardware. Upgrades to a fully digital system are underway. Digitizing additional key signals from the present beam control recently enabled the exploration of automated monitoring methods. Subtle RF issues such as parameter drifts and intermittent anomalies often go undetected, delaying diagnosis until beam quality degrades or operation is disrupted. To address this, we investigate machine learning-based anomaly detection models that aggregate information from low-level RF signals, beam diagnostics, and contextual data (e.g. magnetic field). These models seek to automatically detect abnormal behaviour and connect beam effects with underlying causes linked to the RF systems, supporting both real-time alerts and root-cause analysis. This proactive, data-driven approach aims to shorten the response time to performance degradation, improve reliability, and support preventative maintenance of the PS RF systems.

3:10 PM - 3:30 PM
The phase averaging reference line system provides the RF phase reference , LO and clock signals to the LLRF and other accelerator subsystems. The PIP-II linac has RF systems at three frequencies – 162.5 MHz, 325 MHz and 650 MHz. A temperature-stabilized, low-phase-noise oscillator is used as the master oscillator. Phase reference signals at 162.5 MHz, 325 MHz, and 650 MHz, along with LO signals at 182.5 MHz, 345 MHz, 670 MHz and LLRF clocks at 1320 MHz and 1300 MHz, are generated in temperature-controlled RF modules at each frequency section. A phase reference from each module travels to the next section, where it is doubled to produce required frequencies. The reference also travels alongside the accelerating cavities in the tunnel, allowing cavity probe and reference cables to temperature track and reduce measurement errors from temperature changes or phase drift. The design of the the reference line is described here.

The High Intensity heavy-ion Accelerator Facility (HIAF), currently under construction, will employ a series of superconducting RF (SRF) cavities in its injector linac (iLinac) to accelerate heavy-ion beams. Comprehensive performance validation of each SRF cavity in a horizontal test stand prior to its installation in the accelerator tunnel is a critical prerequisite for the successful commissioning of the iLinac. To this end, we have developed an advanced Low-Level RF (LLRF) automation and diagnostic system for the horizontal test stand of HIAF's low-beta SRF cavities. This system integrates several key functions: high-precision measurement of cavity parameters, automated conditioning at both room and cryogenic temperatures, reliable quench detection, and stable closed-loop operation. The successful application of these advanced strategies not only validates that the cavity performance meets design specifications but also significantly enhances the efficiency and consistency of the testing process, laying a solid foundation for the subsequent installation and commissioning of the HIAF iLinac.

The J-PARC Main Ring (MR) is a high-intensity proton synchrotron that accelerates protons from 3 GeV to 30 GeV. Its output beam power for fast extraction reached 830 kW, corresponding to 2.37 × 10$^{14}$ protons per pulse in March 2025. Coupled bunch oscillation is well suppressed with the newly installed LLRF control system for the MR. Instead of the coupled bunch instability, longitudinal microwave instability is observed in the later part of the acceleration. A new high-speed digitizer is introduced into the LLRF system to monitor the microwave instability. In this presentation, we present the configuration of the digitizer and its preliminary status.
