MHD modeling and synthetic radiographs for high-energy-density plasma flows in shock-shear targets

ORAL

Abstract

Three-dimensional FLASH simulations are carried out to study the hydrodynamics and magnetic fields in the shock-shear derived platform. Simulations indicate that fields of tens of Tesla can be generated via the Biermann battery effect due to vortices and mix in the counterpropagating shock-induced shear layer. Synthetic proton radiography simulations using MPRAD and synthetic X-ray image simulations using SPECT3D are carried out to predict the observable features in the diagnostics.
