Innovative design of an all solid-state high-voltage ns trigger generator, based on magnetic pulse compression and transmission line transformer, is presented. The repetitive trigger pulse generator was developed to trigger a 700 kV trigatron, which has been used to pulse a repetitive intense electron beam accelerator with Tesla transformer charged double pulse forming lines (PFLs). Experimental results show that the trigger pulse generator could produce 180 kV 65 ns duration pulses with a rise time of 20 ns. The repetitive trigger pulses have nice uniform in the voltage waveform. The control time jitter is less then 3 ns. Owing to its good stability and low time jitter, the high-voltage trigger generator is an excellent candidate to trigger the repetitive accelerator.
本文介绍了一种基于磁脉冲压缩和传输线变压器的全固态高压纳秒触发发生器的创新设计。该重复触发脉冲发生器用于触发一台700 kV触发管，该触发管已被用于为带有特斯拉变压器充电双脉冲形成线（PFL）的重复强流电子束加速器提供脉冲。实验结果表明，该触发脉冲发生器能够产生180 kV、持续时间65 ns、上升时间20 ns的脉冲。重复触发脉冲在电压波形上具有良好的一致性。控制时间抖动小于3 ns。由于其良好的稳定性和低时间抖动，该高压触发发生器是触发重复加速器的理想选择。
