摘　　要：直线感应加速器脉冲功率系统工作时伴随着高压开关的闭合会产生强的瞬态电场辐射,可能影响周围的敏感电子设备、仪器的信号或者系统的性能等等。通过对Marx发生器周围进行网格式的测量,总结出了电场辐射的大致分布规律和基本特征。同时还测量了放电回路中的电流信号,经对比分析,表明它和辐射电场在频率150kHz左右都有个主要的谐振峰值,而且都含有高频振荡的成分。The close of high voltage switch in pulsed power system of linear induction accelerator often radiates strong transient electric field, which may influence ambient sensitive electric equipments, signals and performance of other instruments, etc. By performing gridded measurement around the Marx genera- tor, the general distribution law and basic characters of electric field radiation are summarized The current signal of the discharge circuit is also measured, which demonstrates that the current and the radiated electric field both have a resonance frequency about 150 kHz, and contain much higher frequency components.
