兆伏级重复频率三电极气体开关工作特性研究

 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工作特性开展了实验研究，并对实验结果进行了分析。研究结果表明：开关在自击穿工作下的工作稳定性远小于触发工作时，开关工作范围与触发针位置和气压等因素有关；开关电压选择在自击穿电压的大约80％时，开关抖动小、误触发率低，具有较好的工作特性。

Operating characteristics of a MV-class three-electrode repetitive gas switch

Experimental researches on operating characteristics of three-electrode repetitive gas switch were performed on the accelerator CHP01, and experimental results were analyzed. The results show that the switch operates more steadily at trigger mode than at self-breakdown mode and its operating voltage range is related to such factors as the position of the trigger pin and gas pressure. It's also revealed that the switch has excellent operating characteristics, expecially low jitter and low misfire rate, when it operates at about eighty percent of self-breakdown voltage.
