Compact pulse power device for generation of one-dimensional strong shock waves

A compact pulse power device is proposed for generation of one-dimensional strong shock waves, and preliminary experimental results are reported. The cross section of the discharge area is decreased by tapered electrodes to prevent the decay of the shock wave. This new device drives a quasi-one-dimensional strong shock with the front speed 45km∕s in the acrylic guiding tube filled with Xe gas. When the front speed is more than the critical speed Drad, an interesting structure is observed at the shock front, which indicates that the radiative energy transport affects the shock structure.
