Spectral Analysis of Tracer Emission and Absorption Lines in Z-Pinch Dynamic Hohlraum Experiments
Abstract
Spectroscopic analysis of tracer absorption and emission lines is reported for a nested tungsten (W) wire array z-pinch containing an on-axis CH foam with an embedded, thin Al-Mg tracer. The absorption and emission of radiation from the W plasma, the tracer, and the foam are studied with the goal of determining plasma parameters, such as electron temperatures, W composition along the spectrometer (approximately on-axis) line-of-sight, optical depths, and effects of photoionization on atomic populations and spectra. Collisional-radiative calculations are performed using the SPECT3D spectral analysis code. We will present results of our simulations and comparisons with experimental data.
