Laser-Plasma Modeling using Perseus Extended-Mhd Simulation Code for Hed Plasmas

We discuss the use of the PERSEUS extended-MHD simulation code for high-energy-density (HED) plasmas in modeling laser-plasma interactions in relativistic and nonrelativistic regimes. By formulating the fluid equations as a relaxation system in which the current is semi-implicitly time-advanced using the Generalized Ohm’s Law, PERSEUS enables modeling of two-fluid phenomena in dense plasmas without the need to resolve the smallest electron length and time scales. For several laser-target problems in which an ablation plume is generated in the presence of an applied magnetic field, we compare existing experimental and MHD simulation results to extended-MHD results generated using PERSEUS, and examine effects arising from Hall physics.
