Physical Properties and Global Modelling of General Fusion's Magnetized Target Fusion Plasma

POSTER

Abstract

General Fusion's Magnetized Target Fusion (MTF) scheme exists, in parameter space, between magnetic confinement and inertial confinement schemes. We review in this poster the physical parameters of the MTF plasma in relation to static magnetic confinement plasmas and inertial confinement plasmas, noting the similarities and differences that influence the choice of modelling strategies. We discuss the design constraints, operational regime, and goals for plasma performance in relation to other fusion concepts. General Fusion's MTF plasma target is a spherical tokamak configuration, formed into a liquid metal flux conserver. As the converging liquid metal flow compresses the plasma its current, density, and temperature increase. During compression, plasma-wall interactions are important, and simulations suggest that halo currents develop. Tracking development of axial asymmetry during compression requires three dimensional simulations of plasma and liquid metal. Because of these issues, three dimensional global models are useful for understanding device performance. In this poster, we discuss the relevant theory and simulation requirements in General Fusion's MTF regime. We also demonstrate the application of our current modelling tools and progress on our next generation simulation code.
