Study of the effect of plasma shape on accessibility of the second stability regime

Oh Jin Kwon, T C Hender1992年Plasma Physics and Controlled FusionIF 2.2出版社

The effect of plasma shape on the accessibility of the second stability regime is studied numerically. It is shown that, depending on the edge q-value, certain ranges of boundary shapes allow access to the second ballooning stable regime by control of the current profile. The q-profiles used in these sequences are ideally and resistively stable for low-n fixed boundary modes including infernal modes. A tight-fitting, conducting wall is needed to stabilize the n=1 ideal modes for certain boundary shapes.

プラズマ形状が第二安定領域への到達可能性に及ぼす影響を数値的に研究する。周辺q値に依存して、特定の境界形状が電流分布の制御により第二バルーニング安定領域への到達を可能にすることが示される。これらの系列で使用されるq分布は、インフェルナルモードを含む低n固定境界モードに対して理想的および抵抗性に安定である。特定の境界形状に対してn=1理想モードを安定化するためには、密着した導体壁が必要である。
