By the waveform modulation with the pulse form network (PFN) of a small experimental pulsed power system, the saw-tooth waveform, convex-topped waveform and flat-topped waveform are gotten, and the three kinds of pulse current waveforms are used for ...

Abstract:
A high power pulse device called primary test stand (PTS) is under development, which contains 24 modules with identical components, and with the design parameters of 8 MA to 10 MA current and the frontal rise time of 90 ns. For laser triggered gas s...
