Investigations on stratification structure parameters formed from electrical exploding wires in vacuum

The density distribution and the energy deposition in dark and light transverse layers from stratification structures were measured and analyzed from electrical exploding wire experiments in vacuum. It is demonstrated that the differences in the areal density of the dark layer and light layer regions were about 2 x 10(17)/cm(2) at 296 ns after voltage collapsed. This difference corresponded to an energy deposition difference of similar to 2 eV/atom between the dark and light layers, which likely arises from a +/- 10% resistivity perturbation during the explosion, as suggested by combining a gas column expansion model and a thermodynamic model.
