【Abstract】 A laser driven photoemissive high-brightness electron source at Peking Universi- ty is reported.Through a DC accelerating gap of lookV voltage,the device is capa- ble of delivering high-brightness electron beam of 35- lOOps 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.更多还原
