Three Dimensional Modeling of High \ Beta Magnetized Targets for Plasma-jet-driven Magneto-inertial-fusion (PJMIF)

Numerical simulations of compact toroid formation from supersonic plasma jets have been performed using Smooth Particle Fluid with MAXwell equation solver (SPFMax), a smooth particle hydrodynamics (SPH) code supporting the PLX-BETHE project. The physics includes radiation, Braginskii thermal conductivity and ion viscosity, separate ion and electron temperatures, tabular EOS (LTE and non-LTE), nonlocal fusion product deposition, and a novel electromagnetic field solver based on a combination of transmission line theory and Biot Savart's law. Initial plasma jet conditions are derived from the experimental output of Hyperjet-designed plasma guns. Variation in initial velocity, density, temperature, ion species, interpenetration physics, and initial velocity gradients will be included to study the effects on synthetic interferometry, temperature, and pressure within the imploded jets. Primarily this will be a study limited to 36 jets to facilitate comparisons with experimental data available via the PLX-BETHE experiments.
