摘　　要：在电子束泵浦气体激光实验中,大面积均匀电子束是获得高效能激光输出的必要条件。本文介绍了利用SPG-200脉冲功率源产生大面积均匀电子束实验中,利用法拉第筒进行大面积电子束均匀性诊断的研究工作。重点介绍了法拉第筒的测量原理、结构及标定,给出了大面积电子束发射均匀性曲线,并对实验结果进行了分析。In the experiment of gas laser pumped by electron beam, large area uniform electron beam is important to generate high efficiency laser output. This paper introduces Faraday cup is used in the diagnose experiment on the uniformity of large area e-beam generated by SPG-200 pulsed power generator. Construction of Faraday cup and the results of calibration are presented in detail. The uniformity of velvet emission is given, and the results of experiment are analyzed.
