Abstract

Abstract

The high power switch is a key assembly in pulse power generators. The paper introduces the designof a 2 MV laser triggered multi-stage gas switch， and presents the results of its static and triggered experiments on Qiangguang-Ⅰ accelerator. The results show that the design goals are achieved. However， the switch has to face the problem of large transmission electric charge when it works in the transmission line of low impedance. Larger transmission electric charge will cause more discharge products， reducing the insulation capability of the switch and thus directly influencing its lifetime.

- multi-stage multi-channel,
