Abstract：
The precept of DC-SC photoinjector is to combine a DC photoca thode electron gun and the superconducting cavity together.This scheme is specially adequate to provide the high average beam current.In this paper,authors have described the drive laser system for the DC SC photoinjector of PKU version.This system is mainly composed of GE 100 XHP laser,a passive mode locked Nd:YVO₄ laser,CLX 1100 timing controller from TBP,Switzerland,self developed high efficiency SHG and FHG and laser beam transmission system.After experimental test,the laser power of 266nm is more than 1 W,the jitter between laser pulses and the RF reference signal is less than 1 ps.By use of this laser system,we have observed more than 500μA electron current from Cs₂Te cathode.
