摘　　要：介绍了虚火花放电实验 .改变马克斯发生器开关中的放电气体 ,提高了放电的稳定性 .改善虚火花放电室外绝缘油的性能 ,获得了能量为 4 80 ke V,束流为 13k A的电子束 ,电子束的传输距离达到 75cm.证明了摇摆器磁场能提高电子束聚焦性能 .The experiment of pseudospark discharge is discussed in this article. The discharging gas in the switch of Marx generator is changed and hence the stability of discharge is enhanced. The insulation oil outside pseudospark discharge chamber is improved, then the beam with energy of 480 keV and beam current of 13 kA is obtained. The transmission distance of beam is 75 cm. It proves that wiggler field can improve the focusing quality of beam greatly.
