Abstract

The influence of the laser-triggered gas switches' closing time on the peak value and rise time of Z-pinch load current in PTS facility was simulated by a code called FCM-PTS coupled with snow-plow model for the load. It was found that although the one-way transit time difference of triplate transmission lines between top branches and bottom branches was 20 ns, the best time difference of the laser-triggered gas switches' closing time between top branches and bottom branches was 22 ns, which maximized the peak value and minimized the rise time of the load current. When the time difference of the laser-triggered gas switches' closing time was set to 20 ns and 22 ns, 10 ns jitter in the laser-triggered gas switches' closing time could decrease the peak value by up to 163 kA and 136 kA, and increase the rise time by up to 2.4 ns and 2.9 ns, respectively.
