Powerful Pulsed Source with Adjustable Time of Current Rise on the Basis of Helical EMG and Explosive Opening Switch to Drive Solid Liners

Abstract

The facilities for pulsed compression of materials are necessary to study the phase transformations and the dynamic parameters of substances. The acceleration of the solid liners with the help of magnetic field of the explosive magnetic generator (EMG) with subsequent deceleration on a specimen allows carrying out the pulsed compression. The paper describes a powerful pulsed source of current on the basis of helical EMG Oslash240 mm and explosive current opening switch Oslash 300 mm that makes it possible to shape the current pulse with the amplitude 15 MA with rise time adjustable from 3 mus to 10 mus in the liner load.
