Effects of Resistivity and Extended MHD on HED and ICF Experiment Designs

ORAL

Abstract

Ideal MHD is known to insufficient to model most laser-driven laboratory experiments, and especially HED and laboratory astrophysics. But using extended MHD (exMHD) can be computationally expensive, and hard to implement in certain computational frameworks, thus it is important to know which terms are important for designing an HED experiment to study hydrodynamic instabilities, and if resistive MHD is sufficient, or if more terms (e.g. Biermann, Hall, Nernst) are need for more accurate modeling and design. Here we present design for an experiment with a series of simulations to understand the role of resistivity on the modeling and design of a HED Rayleigh-Taylor instability growth experiment under currently achievable laboratory conditions, and implications for other HED and ICF experiments with self-generated and applied fields.
