Shock-induced conduction waves in solids and their applications in high power systems

Abstract

Physical processes in the shock wave accompanied by the electroconductivity changes have been investigated theoretically and experimentally. The analysis based on the classical electrodynamics is performed for the dielectric-metal and metal-metal transitions. This has permitted us to develop the new techniques for experimental investigation of condensed matter in shock waves. Allowance for non-stationary electromagnetic processes in a specially designed measuring cell is the distinctive feature of these techniques. The conductivity value and its dependence on the intensity and the type of loading, the temporal characteristics of the transitions, the behavior under the release and other data are obtained in experiments with the silicon, the ytterbium, the metallic powders and foams. The conclusions have been made regarding the character and the mechanism of the shock-induced phase transitions. The shock-induced conduction waves have been applied to switching the high electric currents and producing the ultrahigh magnetic fields.
