Exploding-Wire-Driven Shock Waves
The explosion of fine silver wires by the fast discharge of a low-inductance capacitor has been photographed with an STL Model C Image Converter Camera operated as a streak camera. All of the previously observed shock waves and contact surfaces have been clearly recorded [1–3]. In addition, the large effective aperture, f/0.5, of the camera, due to its fast optics, 50: 1 light gain, and 0.5-µsec phosphor persistence, has allowed the initial shock wave in air at atmospheric pressure to be photographed by its own luminosity. Photographs of both radially and circumferentially propagating shock waves, depending upon dwell duration, have been recorded during the second conduction phase of the discharges.
