双阳极电子枪测量系统研制与实验

摘要

为测量双阳极电子枪的输出束流品质，设计了一套完善的测量系统。使用该测量系统对双阳极电子枪进行测量。实验结果表明，增加中间电极可提高电子枪输出束流流强并改善横向聚焦。%In order to measure the quality of the beam at the exit of the electron‐gun with double‐anode structure ,an improved measurement system was developed . The electron‐gun was tested by the measurement system successfully .The result shows that the intermediate electrode could increase the electron‐gun’ s output beam current and improve the transverse focusing .
