Abstract :
Issues regarding the generation of cylindrically symmetric dense Z-pinch implosions initiated from multiwire arrays in recent experiments on the Z accelerator at Sandia National Laboratories, Albuquerque, are investigated using the 420-kA, 100-ns XP pulser. Experiments to study merging plasmas from adjacent wires utilize 2 or more Al, Ti, Fe, Cu, Ni, Mo, Pd, Ag, W, Pt or Au wires (13-50 microns in diameter) separated by 0.1-1-mm with up to 125-kA per wire. The explosion phase of the wires is studied with wires carrying at most a few kA each for 30-70-ns. The influence of adsorbates on the wire-generated plasma is being tested by comparing results from initially hot and room temperature W wires
