High-peak and high-average power rectangular pulse generator

A modular high-voltage device, forming in its load electric pulses with amplitudes of 100-200 kV, current 400-800 kA and duration 20 ns is described. The device is intended for the generation of Bremsstrahlung pulses. The device is made on the basis of four generators of GIIR-4/sup 1/ type. Their high accuracy of triggering allows synchronous module operation. The load of the GIIR-4 is either 42 high-voltage cables of KVI-300 type, or a transforming line with a transformation coefficient of 2. The peculiarity of the module is the simultaneous joint charging of the GIIR-4 forming lines and the HV synchronization block from one Marx generator. This allowed an increase in the reliability of device operation and repetition rates up to 20 Hz. Data on module experiments and data concerning the operation resources of the mostly electric strength device units are also presented.
