摘要: 利用峰值功率可达1 GW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0.2 ns，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230 kV，峰值功率1 GW，脉冲宽度6 ns，4路输出脉冲同步偏差95%以上概率分布在1 ns以内，平均同步偏差630 ps。Abstract: 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.
