Abstract：
A laser driven photoemissive high-brightness electron source at Peking University is reported.Through a DC accelerating gap of 100kV voltage,the device is capable of delivering high-brightness electron beam of 35—100ps pulse duration when irradiated with a mode-locked YAG laser.The geometry of the gun is optimized with the aid of simulation codes EGUN and POISSON.The results of experimental studies on ion implanted photocathode and cesium telluride photocathode are given.The proposed laser driven superconducting RF gun is also discussed.
