This LLRF control system operating frequency is 162.5MHz,independently developed by IMPCAS,which consists of RF signal modulation front end,and digital signal process FPGA.The system mainly implements superconductive cavity resonance frequency control,cavity voltage amplitude stability control and phase stability control.The experimental test is completed with a model cavity developed by IMPCAS in room temperature.The twelve-hour test results show that the amplitude stability is 0.32%(peak to peak),±0.18%(RMS),and the phase stability is±0.35degree(peak to peak),±0.09degree(RMS).
