SHOCK PRODUCING MECHANISMS FOR EXPLODING WIRES

Abstract

Single fringe interferograms are presented of 4-mil Cu wires exploded at 20 kv into argon at ambient pressures of 1/8, 1/16 and 1/32 atm. Features discernible include a compressive head shock wave, arc plasma, a weak plasma wave and the expanding metal wire. On the basis of certain plausible assumptions it is seen that the arc plasma has a temperature of about 2.5 ev; but its leading edge, a region not in the thermal equilibrium, has electron temperatures of approximately 100 ev and is the boundary of an electron driven shock wave.
