摘要：

In PAL_XFEL, the specifications of the beam energy spread and rf phase are 0.03%(rms) and 0.01 degrees(rms) respectively. We examined the rf performance in the present PLS 2.5 GeV Linac. The beam energy is changed as much as 0.8% by cooling temperature, air condition, and modulator high voltage jitter. The main factor to change the beam energy is the rf phase drift according to the variation of environmental condition. Dependence of the beam position drift on the rf phase was also examined. For the improvement of the injection beam stability, rf phase feedback system is designed and tested. This paper describes the rf phase feedback and the beam energy feedback system.
