| 摘 要： | 开关脉冲发生器输出的稳定性是影响大口径电光开关可靠性的关键因素，而输出脉冲的触发延时和抖动则是其稳定性的两大重要指标。利用国产VE-4073氢闸管进行了分析和实验研究，通过采用直流加热氢闸管灯丝和氢储存器，以及精确、稳定的双脉冲触发技术，大幅减小了开关脉冲发生器触发延时的抖动和漂移，48 h内开关脉冲发生器输出漂移仅6.1 ns。

| Abstract: | The stability of the switch pulse generator output will influence the reliability of large aperture electro-optic switch synchronizing with the laser pulse. The drift and jitter of the output pulse are important parameters of the stability. The experiments and analyses based on homemade VE-4073 thyratron show that the combined effects of DC heating thyratron and two-pulse triggering technique can greatly reduce the drift and jitter of the pulser output. The output drift of the switch pulse generator depending on these techniques is less than 6.1 ns in 48 h. |
