Ballooning mode stability for self-consistent pressure and current profiles at the H-mode edge

R L Miller, Y R Lin-Liu, T H Osborne, T S Taylor1998年Plasma Physics and Controlled FusionIF 2.2出版社

The edge pressure gradient (H-mode pedestal) for computed equilibria in which the current density profile is consistent with the bootstrap current may not be limited by the first-regime ballooning limit. The transition to second stability is easier for higher elongation, intermediate triangularity, larger aspect ratio, pedestal at larger radius, narrower pedestal width, higher , and lower collisionality.

計算された平衡状態における電流密度分布がブートストラップ電流と整合する場合、エッジ圧力勾配(Hモードペデスタル)は第一安定領域のバルーニング限界によって制限されない可能性がある。第二安定領域への遷移は、より高い伸長度、中間的な三角形度、より大きなアスペクト比、より大きな半径位置でのペデスタル、より狭いペデスタル幅、およびより低い衝突頻度において容易になる。
