摘要: 对TPI1-10k/50型冷阴极闸流管应用的同步特性开展了研究，通过对闸流管触发参数包括储氢加热电压、直流预电离电流、辅助触发脉冲电流、以及主触发脉冲电流的实验研究，实现了该闸流管在工作电压40 kV、工作电流16 kA、脉冲宽度200 ns、重复频率20 Hz条件下，延时抖动约2 ns。另外通过实验研究发现，通过调节触发参数，可以实现开关延时的调节，达到40 ns范围内精确到±1 ns。Abstract: Synchronization characteristics of the cold cathode TPI1-10k/50 thyratron were investigated, through adjusting the hydrogen heater voltage, direct preionization current, pulse preionization current and trigger current. The thyraton can work under 40 kV voltage,16 kA current, 200 ns pulse width and 20 Hz frequency with a jitter of about 2 ns. And the experiment shows that, though adjusting the trigger parameters, the delay can be adjusted by ±1 ns in 40 ns range.
