Nested array dynamics from Ni-clad Ti - Al wire array Z pinches

Summary form only given. Mixed, nested wire arrays with 40 mm and 50 mm outer array diameters were used to investigate the interaction of the arrays and assess radiative characteristics. These arrays were fielded with one array as Al:Mg (either the inner or the outer array) and the other array as Ni-clad Ti (the outer or inner array, with respect to location of the Al:Mg). In all the arrays, the mass and radius ratio of the outer:inner was 2:1. The wire number ratio was also 2:1 in some cases, but the Al:Mg wire number was increased in some loads.This presentation will focus on the analysis of the emitted radiation (in multiple photon energy bins), which has provided insight into the nested array dynamics. In addition, the radiated powers, yields, spectra, and pinhole images have been used to infer plasma conditions and spatial locations for each radiating plasma species. For each species, the initial location of the mass impacts its final plasma location and temperature. Differences were also noted for the 40mm vs. 50mm diameter arrays.
