Abstract:

This report describes experiments to determine the shunting effect of occluded and self generated vapor produced by an exploding wire in a vacuum The investigation of the striation mechanism in exploding wires, these striations have been examined by high speed sequential framing camera to see if they have an axial drift Calculations on the order of magnitude of the Hall energy, results show that for a given sample, about 13 more energy is required to melt the sample than is accounted for in simple thermodynamic arguments The development of an experimental flash x-ray technique for determining the instantaneous density of the vapor produced by an exploding wire and The development of a three-color optical pyrometer with fast response time. The unit, in breadboard form, has been calibrated, and used to obtain preliminary results from exploding wires. The results are expressed in the form of a trace on a cathode ray oscilloscope, whose vertical displacement is proportional to the temperature.
