| 摘 要： | 以“CHP01”加速器为实验平台，对自行研制的重复频率三电极气体开关的自击穿特性开展了实验研究。研究了开关自击穿特性与气压、气流流速、电极形状等因素的关系，并对实验结果进行了分析。结果表明：随着气压的升高，开关自击穿电压分散性变大；适当流速的气流有助于减小开关的自击穿分散性，但气流流速过大将加大自击穿分散性；当通过改变电极形状增大极间场增强因子时，开关电极间场增强因子变大，开关分散性减小，但平均自击穿电压有所降低。

| Abstract: | Experimental researches on self-breakdown characteristics of three-electrodes repetitive gas switch, including relationship between the self-breakdwon characteristics and gas pressure, gas flow speed and electrode shape, were performed on the accelerator CHPO1. The results show that the deviation of self-breakdown voltage of the switch increases greatly as gas pressure rises, and proper gas flow speed is helpful to decrease the deviation but too high gas flow speed may result in greater deviation. It is also revealed that deviation and average value of self-breakdown voltage of the switch decrease as field enhancement factor increases by adjusting the electrode shape. |
