摘要：The fast-ion transport during neutral beam injection on the Experimental Advanced Superconducting Tokamak (EAST) is studied. Based on the NUBEAM and TRANSP codes, it is found that fast-ion transport is anomalous when the minimum safety factor (q(min)) is about 2, while it is neoclassical when q(min) is around 1. Neutral beam injection heating efficiency, plasma stored energy, and the total heating power are reduced when the fast ion transport is anomalous. The Alfven continuum spectrum and the mode structures of toroidal Alfven eigenmodes (AEs) are also calculated for comparison between neoclassical fast-ion transport and anomalous fast-ion transport. High-q(min) discharge with anomalous fast-ion transport has more AE activity than that of lower q(min) discharge with neoclassical fast-ion transport.
