| 内容記述 | Stable toroidicity-induced Alfvén eigenmodes (TAEs) with low toroidal mode number (n = 1 and n = 2) were excited by application of alternating magnetic field perturbations generated with a set of electrodes inserted into the edge region of neutral beam injection heated plasmas on the Compact Helical System [ K. Nishimura, K. Matsuoka, M. Fujiwara et al., Fusion Technol. 17, 86 (1990) ]. The gap locations of TAEs excited by the electrodes are in the plasma peripheral region of ρ>0.7 (ρ is the normalized minor radius) where energetic ion drive is negligibly small, while some AEs are excited by energetic ions in the plasma core region of ρ<0.4. The damping rate of these stable TAEs derived from plasma responses to applied perturbations is fairly large, that is, ∼ 9% to ∼ 12% of the angular eigenfrequency. This large damping rate is thought to be dominantly caused by continuum damping and radiative damping. | |||||
