摘要
A new tuner control system for spoke superconducting radio frequency（SRF） cavities has been developed and applied to cryomodule I of the C-ADS injector I at the Institute of High Energy Physics, Chinese Academy of Sciences. We have successfully implemented the tuner controller based on Programmable Logic Controller（PLC）for the first time and achieved a cavity tuning phase error of ±0.7？（about ±4 Hz peak to peak） in the presence of electromechanical coupled resonance. This paper presents preliminary experimental results based on the PLC tuner controller under proton beam commissioning.
