Repetitive pulsed-power generator "ETIGO-IV"

"ETIGO-IV," a new repetitive pulsed-power generator, has been developed. It is capable of delivering, to a matched load, an output pulse of 400 kV in peak voltage, 13 kA in peak current, and 120 ns in pulse length, at the repetition rate of 1 Hz. It is aimed at applications to material development, pulsed ion-beam acceleration, and high-power microwave generation. This paper reports the design details and operation results of "ETIGO-IV," as well as the initial experimental results on electron beam generation.
