Development of MC55 low impedance intense pulsed electron beam accelerator

The principle and parameters of a low impedance pulsed electron accelerator MC55 are described. The experimental waveforms of the electron beam produced by MC55 are also presented. MC55 consists a 24-stages Marx generator, a 10 Ω water coaxial pulse forming line and outputting line, a main gas switch and a vacuum diode. An intense pulsed electron beam with diode voltage of 500 kV, current of 50 kA, and pulsewidth of 50 ns can be produced by this accelerator. The experimental research of coaxial virtual cathode oscillator driven by MC55 is carried out.
