The source of high-voltage pulses. described in the paper. is a two-stage sharpening system that consists of a helical explosive magnetic generator and explosive and electroexplosive current opening switches separated by a current transformer. The helical explosive magnetic generator provides a stored energy of 1 MJ at a current of /spl sim/1.5 MA and a rise time of 40E10/sup -6/ s in an inductive load of 1E10/sup 6/ H. The cascade of the explosive current opening switch and the transformer reduce the pulse duration to 1E10/sup -6/ s. The electroexplosive opening switch is made from thin copper wires placed between layers of polyethylene insulation. The total length of the explosive magnetic pulsed power generator is about 3 m, its diameter being 300 mm. The voltage pulse, with 1.2 MV amplitude and 0.3E10/sup -6/ s duration, has been recorded on the output electrode at a connected load with an impedance of 15 Ohm.
