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 ¿240 mm and explosive current opening switch ¿300 mm that makes it possible to shape the current pulse with the amplitude 15 MA with rise time adjustable from 3 ¿s to 10 ¿s in the liner load. The described pulsed source of current was used in the experiment on acceleration of the quasi-spherical liner. With the availability of powerful pulsed sources of magampere level current with a microsecond rise time it is possible to solve a number of problems in the experimental physics. Such problems include the study of the liner implosion, obtaining of the limiting energy densities, study of behavior of various materials under conditions of megabar loading, etc. At present the explosive magnetic generators (EMG) whose operation principle is based on magnetic flux compression by an explosive charge are the most powerful pulsed sources [1]. The EMG can be adopted for different conditions of experiment performance; they are transportable and have a moderate cost.
