Analysis for Self-Emission from Spherical Shock Experiments

ORAL

Abstract

Measurements of the self-emission produced by a strong spherically converging shock wave driven by the OMEGA laser are analyzed using a Bayesian model-fitting procedure. Various models are used, including semi-analytic and hydrodynamics codes, and the results are compared. The primary measurements being used to constrain the models include DD neutron production and x-ray self-emission. The systems studied include solid density targets made of deuterated plastic and gas density exploding-pusher targets designed to be hydrodynamic in nature. The model fitting gives insight into the physics mechanisms that dominate the self-emission from these types of experiments. This material is based upon work supported by the Department of Energy National Nuclear Security Administration under Award Number DE-NA0003856.
