Shaper of a current pulse of megaampere level with rise time of 100 ns

Abstract

The paper presents the method of shaping the current pulse of submegampere level with the rise time of 100 ns. At this a device on the basis of an explosive magnetic generator can be the source of the original current of microsecond duration. A low-inductive foil electrically exploded current opening switch designed at VNIIEF and a vacuum discharger developed at the RSC KI under “Baikal” program are used to shape the current pulse with required parameters. To test the proposed method of the current pulse shaping, the configuration of a series of explosive experiments has been worked out. The helical explosive magnetic generator with the explosive current opening switch is used as the energy source. In the experiments it is proposed to get the current pulse with the amplitude 4–5 MA and rise time of ∼100 ns in the load of ∼10 nH. The results of the experimental checking of the experiment configuration under laboratory conditions on the facility with capacitive energy storages will be given. The results of the first explosive experiment will be described and analyzed.
