皮秒微脉冲电子束团诊断

DIAGNOSTICS FOR PICOSECOND ELECTRON-BEAM BUNCH

摘要: 介绍一种基于皮秒扫描相机的微脉冲电子束团诊断系统和实验方法。该系统具有很高的灵敏度、皮秒的时间分辨能力和机动灵活的特点,满足射频直线加速器和储存环上电子束团诊断的要求。在我国,我们首次利用该类系统测量了北京正负电子对撞机(BEPC)储存环中脉冲电子束团的波形和初步测量了北京自由电子激光装置射频直线加速器的微脉冲电子束团的时间分布。

Abstract: A picosecond electron - beam bunch diagnostic method with a streak camera is introduced. Some preliminary experiments on the Beijing Electron and Positron Collider and the Beijing Free - Electron Laser Fasility have used this system. The results are presented.
