Control Architecture and Strategies

Oral

Elettra 2.0 control system will consolidate time-critical acquisition, processing, and actuation onto a dual HPC 512 HT core server. Using the DPDK kernel bypass, this data plane is designed to acquire Turn-by-Turn streams from 168 BPMs, 4 LLRFs and 120 BLMs, and drive about 1200 magnet power supplies at 100 kHz for RT feedback purposes, with a total of 160 Mpps data rate with a few...

Control Hardware Platforms

Oral

The High-Luminosity Large Hadron Collider (HL-LHC) project at CERN is set to introduce a series
of major upgrades across the LHC complex, including the implementation of crab cavities,
applied for the first time in a hadron machine. These cavities are designed to increase beam
luminosity by compensating for the geometric luminosity reduction caused by the crossing
angle at the interaction...

21. The Development of Feedback Systems at SSRF and SHINE

Control Hardware Platforms

Oral

Shanghai Synchrotron Radiation Facility (SSRF), a third-generation light source in operation since 2009, is upgrading its fast orbit feedback system with new MPSoC FPGA-based digital electronics, alongside developing an in-house bunch-by-bunch feedback system based on RFSoC FPGA. Meanwhile, Shanghai High Repetition Rate XFEL and Extreme Light Facility (SHINE), a 3-km-long continuous-wave...

37. Obsidian: a compact platform for scalable and intelligent acoustic-band active stabilization control

Qiang Du (Lawrence Berkeley National Laboratory)

Control Hardware Platforms

Oral

Optimal beam parameters in high-power lasers and accelerators require active stabilization against environmental perturbations. Typically residing in the acoustic frequency band, these perturbations are corrected via piezo actuators or magnets. Common applications include coherent laser combining, laser pointing stabilization, resonance control in superconducting radio-frequency (SRF)...
