摘要
通过对触发管型气体火花开关触发机理和电极结构的分析,提出了圆盘型、齿轮型及多针型等新的触发电极。实验表明,这三种触发电极除多针型外都具有稳定工作性能,触发范围与常规针状电极结构相当,在纳秒前沿的触发脉冲作用下抖动可低于10 ns。其中,采用齿轮状触发电极结构,在幅值22 kV(约为主间隙静态击穿电压的20%)、前沿10 ns的触发脉冲下,触发最小时延为77 ns,抖动为2.5 ns。
The lifetime of conventional trigatron is limited by the erosion of the trigger electrode. An extended lifetime trigatron was designed with three new types of trigger electrode based on the analysis of trigger mechanism. The experimental results indicate that the performances of the new trigatron are as high as the conventional trigatron. The minimum delay time of the new trigatron is 77 ns and the jitter is 2.5 ns.
