Explosive magnetic generator of high-power voltage pulses of 1 MV amplitude and 0.3 microsecond duration

Abstract

Summary form only given, as follows. The source of high-voltage pulses, described in the paper, is a two-stage sharpening system that consists of a helical explosive magnetic generator, of explosive and electroexplosive current opening switches separated by a current transformer. The helical explosive magnetic generator provides the stored energy of 1 MJ at the current of /spl sim/1.5 MA and the rise time of 40 microsec in the inductive load of 1 microH. The cascade of the explosive current opening switch and the transformer reduces the pulse duration to 1 microsec. An electroexplosive opening switch is made from thin copper wires placed between the layers of polyethylene insulation. The total length of the explosive magnetic generator of pulses is about 3 m the diameter is 300 mm. The voltage pulse with 1.2 MV and 0.3 microsec duration has been recorded on the output electrode at a connected load with the impedance of 15 Ohm.
