Abstract

The first test of a pulsed power system consisting of a five-element disk magneto-cumulative generator with high-explosive charges of 240 mm diameter and an explosive current opening switch with ribbed barrier was carried out in the frameworks of a program for creating an explosive complex EMIR, intended for the generation of high-power soft X-ray radiation pulses. A current pulse of ~ 9 MA with a characteristic rise time of ~ 0.6 μs was recorded at opening of the generator circuit with the current of ~ 15 MA into a ~ 7 nH inductance load.
