Effects of kinetic resonances on the stability of resistive wall modes in reversed field pinch

D Yadykin, Y Q Liu, R Paccagnella2011年Plasma Physics and Controlled FusionIF 2.2出版社

The kinetic effects, due to the mode resonance with thermal particle drift motions in the reversed field pinch (RFP) plasmas, are numerically investigated for the stability of the resistive wall mode, using a non-perturbative MHD-kinetic hybrid formulation. The kinetic effects are generally found to be too weak to substantially change the mode growth rate, or the stability margin, re-enforcing the fact that the ideal MHD model is rather adequate for describing the RWM physics in RFP experiments.

反転磁場ピンチ(RFP)プラズマにおける熱粒子ドリフト運動とのモード共鳴による運動論効果が、抵抗性壁モードの安定性に対して非摂動的MHD-運動論ハイブリッド定式化を用いて数値的に調査された。運動論効果は一般に、モード成長率または安定余裕を実質的に変化させるには弱すぎることが見出され、このことは、RFP実験におけるRWM物理を記述するには理想MHDモデルがむしろ適切であるという事実を再確認するものである。
