Quantitative investigation of mass ablation rates of wire arrays at current levels from 80kA to 1MA

POSTER

Abstract

We present investigations of mass ablation rates in x-pinches and wire arrays at different current levels. Interferometry and radiography are used with x-ray framing cameras to investigate ablation from 80 kA to 1MA. The radial ablation flare structure is studied, along with the formation of precursor plasma structures. Quantitative comparisons will be made to analytical and MHD modeling.
