Abstract

Summary form only given. Wire array z-pinches on the Z generator are bright sources of radiation from 200eV to 9keV. Typically, wire materials are varied to provide emission in a specific spectral band, and the array setup is varied in order to provide appropriate energy per ion to heat the stagnated plasma to an electron temperature conducive to efficient emission within that band. Here we discuss a series of experiments where the wire material is varied (Al, Stainless Steel, Cu, W), however the array setup is fixed at 65mm diameter and 2.5mg mass. We discuss similarities and differences in the implosion dynamics and the differences in the plasma conditions achieved at stagnation. We will explore the changes in total, thermal K-shell and non-thermal K-shell emission between the different materials.
