A pressure pulse of several kilobar amplitude and a fraction of a microsecond duration is required for experimental studies of dislocations moving in metal crystals at velocities of the order of the velocity of elastic waves. A technique for generating such pulses by means of an exploding aluminum foil is described. The aluminum foil is rapidly vaporized by a capacitor discharge while it is confined between elastic plates.
