Aluminum Wire Array Experiments on the Z Generator*

Wire array Z-pinches consisting of Al wires are a bright source of $>1$~keV emission. We discuss data from recent experiments with large diameter Al wire array Z-pinches on the Z generator. Wire arrays at 40mm, 50mm and 65mm were imploded on the Z generator. Soft x-ray self-emission imaging is used to study the implosion dynamics. Spectroscopy is used to diagnose plasma conditions as material stagnates on the axis. Data indicates significant free-bound continuum emission is present. We will discuss the variation in plasma conditions and emission characteristics as the initial wire array setup is varied.
