Fast Particle Destabilization of TAE Type Modes in NSTX, JT-60U and Proposed Burning Plasma Devices

摘要

The properties of fast ion driven TAEs are studied in National Spherical Torus Experiment (NSTX), JT-60U, and proposed DT burning plasma experiments in International Tokamak Experimental Reactor (ITER), FIRE, and IGNITOR, and JET DT operation. Unstable TAEs have been observed in NSTX and JT-60U experiments to cause significant fast ion loss. Theoretical studies employing the global kinetic-MHD stability codes, NOVA/NOVA-K code, and a high-n non-pertiirbative HINST code have been performed, and the analysis explains well the experimental results. For the proposed DT burning plasma experiments TAEs are expected to be unstable in ITER and FIRE.
