Design and Performance of Digital BPM Processor for DCLS and SXFEL

Abstract A digital BPM processor has been developed in SINAP, which can be used on the signal processing of both stripline BPM and cavity BPM. The processor is a standalone system and providing 4 channels 120MS/s, 16 bits ADC and powerful Virtex-5 FPGA. The processor has been mas applied on Dalian Coherent Light Source (DCLS) and Shanghai X-ray FEL (SXFEL). The processor specification and performance evaluations including lab and beam tests will be introduced.
