Impedance characteristic of wave erection Marx generator

A 10-stage wave erection Marx generator is designed and set up by using 50 kV non-inductive capacitors and solid resistors, which realizes the miniaturization of pulse power modulator with capacitance energy storage. The impedance characteristic of the generator is experimentally studied by utilizing water resistor loads with different resistance, and further estimated to be about 45 Ω by utilizing a metal film resistor load of 90 Ω which makes the discharging circuit critically damped. For 40 kV charge, an output high voltage pulse with amplitude of about 210 kV, full width half maximum (FWHM) of about 40 ns, and rise time of 5 ns is obtained on the metal film resistor load. This voltage pulse generator is applied to drive a fieldemission diode successfully. For a cathode-anode gap of
