Electromagnetic torque on the toroidal plasma and the error-field induced torque

V. D. Pustovitov2007年被引用 15Nuclear FusionIF 3出版社

The electromagnetic torque on the toroidal plasma is calculated assuming a linear plasma response to the applied perturbation, which may be the error field or the field created by the correction coils, or both. The result is compared with recently published expressions for the error field induced torque (Zheng et al2006 Nucl. Fusion46 L9, Zheng and Kotschenreuther 2006 Phys. Rev. Lett.97 165001), and the conclusions of these papers are revised. We resolve the problem of the torque resonance raised there. It is shown that the strong increase in the torque due to the static error field must occur at the resistive wall mode stability limit and not at the no-wall stability limit.

トロイダルプラズマ上の電磁トルクは、印加摂動に対する線形プラズマ応答を仮定して計算される。この摂動は、誤差磁場または補正コイルによって生成される磁場、あるいはその両方であり得る。この結果は、誤差磁場誘起トルクに関する最近発表された式(Zheng et al 2006 Nucl. Fusion 46 L9、Zheng and Kotschenreuther 2006 Phys. Rev. Lett. 97 165001)と比較され、これらの論文の結論は修正される。我々はそこで提起されたトルク共鳴の問題を解決する。静的誤差磁場によるトルクの強い増加は、無壁安定性限界ではなく抵抗性壁モード安定性限界で発生しなければならないことが示される。
