概要
- 論文の詳細を見る
Using a fast camera with tangential view, the motion of the filamentary structures in peripheral regions was observed. In the L-mode, the filamentary structures are relatively thinner than those of the H-mode. The direction of filamentary structure motion in the H-mode plasma was changed opposite to that in the L-mode plasma, and the motion speed was also doubled. During L-H transition, this motion was stopped. If this motion is poloidal rotation due to Er × B drift, Er should be positive in the L-mode plasma and negative in the H-mode plasma.
