A compact, low cost Marx bank for generating capillary discharge plasmas

Abstract:

We describe in detail a low power Compact Marx Bank (CMB) circuit that can provide 20 kV, 500A pulses of approximately 100–200 ns duration. One application is the generation of capillary discharge plasmas of density ≈ 1018 cm􀀀3 used in laser plasma accelerators. The CMB is tiggered with a high speed solid state switch and gives a HV output pulse with a ns scale rise time into a 50Ω load (coaxial cable) with < 4 ns voltage jitter. Its small size (10 cm × 25 cm × 5 cm) means that it can be p...
