高压多脉冲真空间隙击穿实验研究

 在真空间隙击穿机理的理论基础上，设计了高压多脉冲下真空间隙的击穿实验方案，对相同材料的多对电极间隙在高压单脉冲和三脉冲下的真空击穿特性进行了实验研究。实验结果与脉冲下真空间隙的击穿机理相符，对脉冲数量增加对真空间隙宏观击穿场强的影响进行了验证，推断出了决定真空间隙宏观击穿场强的关键因素，并对多脉冲加速间隙最大宏观场强的设计提出了建议。

Experimental research for vacuum gap breakdown in high voltage multi-pulse

Base on the breakdown theory of vacuum gaps, experiments have been done to find out the breakdown electric field intensities in high voltage single-and triple-pulse for 26 vacuum gaps with different shapes. The experimental results match up to the theory and confirm the effect of the pulse-number increase on the breakdown electric field intensity. The key point to decide the macroscopical breakdown electric field intensity of a vacuum gap has been pointed out with some advises about the design of a multi-pulse linear inductive accelerator’s accelerate gap.
