Simulation Overview of High-Performance Beam-Driven FRCs

The C-2U experiment [1] presents a unique combination of challenges to simulation: a dynamic formation process, high beta ($\sim 85\%$ average) and large ion orbits, neutral beam heating and energetic particles, coupling of core transport with the SOL, and electrode biasing of the SOL. These challenges have been addressed with a suite of codes, including extended MHD simulation of dynamic theta-pinch formation, translation, and collision; Monte Carlo simulation of Neutral Beam heating; 3D hybrid PIC code simulation of the influence of neutral beams and end-biasing on macrostability; 3D PIC simulation of turbulent transport; PIC simulation of beam driven plasma modes; hybrid fluid/particle transport simulation of heating, fueling, and current drive; kinetic simulation of parallel electron transport in the Scrape Off Layer; and neutral particle transport. \newline$[1]$ M.W.
