Spectroscopic Modeling of Mo Planar Wire Arrays produced on the 1 MA Zebra generator at UNR

POSTER

Abstract

Planar wire arrays produce the record-high peak powers and yields in sub-keV and keV among all other configurations of the X- and Z-pinch loads tested on 1 MA UNR Zebra [1]. In particular, Mo planar wire arrays implosions showed the maximum radiation yield of all wire materials tested on this device so far ($\sim $ 18 kJ) and the highest L-shell plasma electron temperature Te$\ge $800 eV. To estimate and analyze evolution of plasma parameters in space and time, spatially-resolved, time integrated and time-gated, spatially integrated L-shell Mo spectra were collected and analyzed. An earlier developed and successfully used non-LTE kinetic Mo model [2] was applied in the present work. Results are compared with the previous results on UNR Zebra Mo X-pinches and SNL-Z Mo nested wire arrays [3]. References: [1]. V.L. Kantsyrev, A. S. Safronova, D. A.
