Solid Discharger for the Systems Forming a Current Pulse in Low-Impedance Loads of Inductive Storages of Electromagnetic Energy.

The paper considers the use of a solid discharger with a cathode localized enhancement of electric field working together with an opening switch of an inductive storage to form a quick-rising current pulse in a low-impedance load. The physical factors bringing to an increase in pulse sharpening efficiency are specified. The discharger geometry variant is proposed. The technique for a determination of its parameters depending on the experimental requirements and conditions is described. The paper presents the results of the experiments on a stationary facility demonstrating a possibility to generate the current pulses with a rise front ∼100 ns in the inductive loads ∼10 nH. The obtained results allow giving a recommendation to use this type of dischargers to form multi-megaampere current pulses with submicrosecond rise front (up to ∼100 ns) for the inductive energy storages and, in particular, for the explosive magnetic (magnetocumulative) generators, in the circuits with low-impedance loads.
