Abstract Text:
How do biased, beam driven FRCs work? We will try to answer this question while giving an overview of the FRC research program at Tri Alpha Energy (TAE) from a theory and simulation perspective. The C-2U experiment [1] presents a unique combination of challenges to simulation: a dynamic formation process, high beta (~85% average) and large ion orbits, neutral beam heating and energetic particles, strong 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. Quantitative comparisons with the C-2U experiment will be made for each of these topics.
