Anisotropy and shaping effects on the stability boundaries of infernal ideal MHD modes in tokamak hybrid plasmas

D Brunetti, C J Ham, J P Graves, C Wahlberg, W A Cooper2020年Plasma Physics and Controlled FusionIF 2.2出版社

Anisotropy and some limiting toroidal flow effects on the stability of nearly resonant ideal magnetohydrodynamic modes in hybrid shaped tokamak plasmas are investigated within the ideal MHD infernal mode framework. Such effects are found to alter the plasma magnetic well/hill, which can be interpreted as imparing the average curvature, and the strength of mode coupling. In line with previous results, it is found that better stability properties are achieved through deepening the magnetic well by special cases of uniform toroidal flow and parallel plasma anisotropy. Plasma shaping provides additional modifications to the magnetic well depth, whose global stabilising or destabilising effect depends on the mutual interplay of elongation, triangularity and toroidicity. Further stabilisation is achieved by weakening the mode drive in vertically elongated plasmas.

異方性とトロイダル流のいくつかの制限的な効果が、ハイブリッド形状トカマクプラズマにおけるほぼ共鳴する理想磁気流体力学モードの安定性に及ぼす影響を、理想MHD内部モードの枠組み内で調査した。このような効果は、プラズマの磁気井戸/磁気丘を変化させることが見出され、これは平均曲率の変化と解釈でき、またモード結合の強さも変化させる。これまでの結果と一致して、一様なトロイダル流と平行プラズマ異方性の特別な場合において磁気井戸を深くすることにより、より良好な安定性特性が達成されることが見出された。プラズマ形状は磁気井戸の深さにさらなる修正をもたらし、その全体的な安定化または不安定化効果は、伸長度、三角形度、およびトロイダル度の相互の相互作用に依存する。さらに、垂直に細長いプラズマではモード駆動を弱めることにより、さらなる安定化が達成される。
