Experimental research on synchronized operation of 4 parallel-connected 1 GW nanosecond pulse generators

利用峰值功率可达1GW的纳秒脉冲源CKP1000开展了4路GW级纳秒脉冲源同步技术实验研究。使用trigatron作为触发开关,通过单路开关触发特性实验研究优化了开关的结构与工作参数,单路开关抖动0.2ns,建立了实验装置,实现了4路GW级纳秒脉冲源并联同步输出。同步实验结果为:纳秒脉冲源输出电压230kV,峰值功率1GW,脉冲宽度6ns,4路输出脉冲同步偏差95%以上概率分布在1ns以内,平均同步偏差630ps。

Experimental research on synchronized operation of 4 parallel-connected 1 GW nanosecond pulse generators is presented.With trigatron as trigger switch,the synchronized operation is successfully achieved.The jitter time of trigation is 0.2 ns.The mutual spread of four 6 ns wide pulses is lower than 1 ns（probability above 95%） with an average value of 630 ps at a peak power of 1 GW（230 kV on 50 Ω load） of each parallel-connected module.
