Comprehensive Analysis of Implosions of Single Planar Tungsten Wire Arrays with Aluminum Center Wires Produced on a 1-MA generator

POSTER

Abstract

An analysis of five-wire W single planar wire array (SPWA) experiments with Al center wires is presented. Comparisons are drawn to previous work which focused on SPWAs with smaller inter-wire gaps of pure W loads and W loads with single Al wires on the edge of the array. Experiments were performed on the 1MA generator ``Zebra'' at UNR, with data taken on a pulse laser shadowgraphy apparatus, an x-ray time-gated pinhole camera, and both time-integrated spatially resolved and time-gated spatially integrated spectrometers. Utilizing this full suite of plasma diagnostics, comprehensive set of data with staggered timings has been compiled. Non-LTE kinetic modeling is used to describe temperature and density features of the spectral data, while the Wire Ablation Dynamics Model is utilized to better understand implosion dynamics.
