STRUCTURAL RESPONSE TO INTENSE ELECTROMAGNETIC RADIATION.
Abstract
An exploding wire apparatus was used to study conversion of electrical energy into strain en ergy in glass samples that were either irradiated by the electromagnetic waves emitted by the wire or enveloped by plasma formed by the wire. The strain energyleft permanent marks on the sample as discoloration, weight loss, and surface cracks. These were used to confirm the theoretical analy sis as to method and to dimensions. Conversion of energy within the sample was postulated to in volve thermal absorption, diffusion, and strain. The thermal diffusion equation was solved and values computed for the heating and cooling por tions of the pulse. By linking the quantity of material heated with experimental measurements, an overall absorption coefficient for glass of 10 to the 3rd power per cm and an energy deposi tion of 1/2 joule/sq cm was found. The large absorption coefficient indicates that most of this energy radiated by the wire must be in the ultraviolet portion of the spectrum. (Author)
