Opacity on NIF: Post Shot Analysis of FeMg Simulation versus Experiment

ORAL

Abstract

Los Alamos and Livermore National Labs are engaged in a series of experiments on the National Ignition Facility (NIF) to produce opacity data for iron and other elements. These data may help constrain the radius at which the solar interior transitions from the radiative zone to the convective zone in Solar models. Forward model simulations are done with the radiation-hydrodynamic code CASSIO and post-processed with the ray-tracing code FESTR. Here we present our initial comparison of experimental and simulated spectrally dependent transmission results for FeMg at conditions of roughly 155 eV and 1022 electrons/cm3.
