Full circuit simulation for electromagnetic pulse forming and transmission in the PTS facility

In order to study the electromagnetic pulse forming and transmission in the PTS facility, and to optimize the performance to get the desired driving currents for the load design, a full circuit model were founded to describe the charging and discharging process for all the key circuit elements in detail. The model and parameters were validated and the numerical results coincided with the experimental results. For typical Z pinch loads, the compression of the pulse and the amplification of the pulse power were simulated, as charged at a voltage of 65 kV, the PTS facility delivered about 1 MJ energy to the stack region. For typical isentropic compression experiments, the timing of the laser triggered gas switch was designed for different loads, and the tailored currents with about 6 MA in peak and 450 ns(0-100%) in rise time were obtained in the load region from simulation for shot 0121.
