概要
- 論文の詳細を見る
The triggering instability of the annular crash observed in NBI-heated plasmas of the CHS heliotron/torsatron is investigated. Two types of m~2/n = 1 magnetic fluctuations, fishbone-like burst mode and low frequency ideal/resistive interchange mode, respectively, grow just before the crash. Time evolution of the amplitude and phase inversion radius of these modes indicate that the low frequency interchange mode is the main triggering instability of the sawtooth crash in CHS.
