摘要
介绍了北京大学激光驱动光阴极高亮度电子束源,给出了其物理设计.该装置采用激光照射光阴极,通过100kV 直流加速结构,产生35-100ps 的高亮度电子束,给出了新型离子注入型光阴极和碲化铯光阴极的实验研究结果.讨论了即将建造的超导光阴极高亮度注入器.
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.
