Self-Generated Magnetic Fields in High Energy Density Laboratory Experiments
ORAL
Abstract
High Energy Density (HED) laboratory experiments to study hydrodynamic instabilities have been developed over the last several years on Omega and NIF. We model these experiments with multi-physics hydro-dynamic codes under the assumption that any magnetic fields produced in these plasmas will not affect the bulk hydro. In many cases this is likely a valid assumption; however, as we try to ever focus our understanding on smaller and smaller scale phenomena in HED experiments we begin to see more and more discrepancies with our pure hydro models. Our project aims to create and diagnose self-generated fields in platforms similar to our HED hydro experiments to quantify how large these fields can become and how these fields can affect the small scale hydro evolution of these platforms. Namely, when the energy density of phenomena are on par with the magnetic energy density, as can be in turbulence, how are small vortices affected, how do B fields change the dissipation scales, and how do changes in heat conduction change the distribution of modes?
