设计了一种Trigatron开关,以Tesla型GW级纳秒脉冲源为实验平台,实验研究了不同电压极性组合、触发电压、触发间隙、触发极直径和触发脉冲宽度对开关触发特性的影响.实验研究结果表明:开关电压极性组合、触发电压、触发间隙对开关触发特性影响较大,在各欠压比条件下差异均十分明显,触发极直径和触发脉冲宽度对开关的触发特性影响较小.根据实验结果优化了开关结构和工作参数,获得的开关抖动最低可达0 1 ns.

A trigatron switch was designed for a gigawatt nanosecond pulse source of Tesla type. For achieving subnanosecond jitter, experimental research was conducted under different voltage polarity combination, trigger voltage, trigger gap, trigger pin diameter and trigger pulse width. The results show that voltage polarity combination, trigger voltage and trigger gap have significant influence on triggering characteristics. The influence of trigger pin diameter and trigger pulse width is relative small. The trigatron switch was optimized according to the experimental results and a jitter of 0.1 ns was achieved.
