Spectroscopic diagnostics of laser produced plasmas
A detailed phenomenological study of the spectroscopic analysis of laser produced plasmas is presented in this dissertation. High resolution x-ray spectroscopic data have been obtained in pellet implosion experiments using the 24 beam Omega laser system at the University of Rochester Laboratory for Laser Energetics. Line broadening theory was applied to diagnose plasma core temperatures and densities from observed spectral line shapes; detailed atomic physics models were constructed to diagnose core parameters from sensitive line intensity ratios. This study attempts to systematically observe the effects of opacity on the diagnostics by a self consistent analysis of x-ray spectra obtained from implosions of argon and neon filled glass microballoons differing in diameter, wall thickness, and Ar/Ne fill ratio. The subsequent analysis then includes opacity effects through the use of a radiation transport model for the spectral lines; atomic physics models are studied and the final results systematically compared with the experimental results.
