Spectroscopic Study of Neon Z-Pinch Plasma for Sodium-Neon Photopumping Experiments

Abstract

Spectroscopic measurements were made of neon Z-pinch plasmas to establish conditions appropriate for sodium-neon photopumping. Emissions of soft X-rays, extreme ultraviolet (XUV), and near ultraviolet (NUV) were measured. Plasma electron temperatures and densities were determined by comparing measurements with steady-state and time-dependent atomic-physics models. Dependences of plasma emissions on the magnitude and risetime of the current and on the initial mass loading were investigated. Peak currents of 120 to 300 kA and 1-microns to 50-ns risetime were used to implode a 1-cm diameter neon gas puff. Mass loadings ranging from 1.2 to 3.6 microng/cm were varied by adjusting the gas-puff pressure. Adjustments of the current, current risetime, and mass loading can be used to produce an appropriate neon plasma for sodium-neon photopumping.
