Description
Beam Position Monitor (BPM) and Fast Orbit Feedback (FOFB) electronics are critical for ensuring the stability of synchrotron light sources. As part of the intelligent and digital upgrade of the Shanghai Synchrotron Radiation Facility (SSRF), significant enhancements are being made to these electronics, targeting improved beam-position measurement resolution and the integration of precise time-stamping functionality. This upgrade employs MPSoC FPGAs as the system controllers and digital signal processors. The BPM electronics generate a pilot-tone signal to improve measurement resolution and integrate a White Rabbit timing card for accurate synchronization. The FOFB electronics receive high-speed acquisition data from the BPM modules via 10 Gb SFP links and perform real-time feedback computations directly on the FPGA. This paper presents the overall electronics design and details the ongoing upgrade process at SSRF.
