The penetration dynamics of the resonant magnetic perturbation (RMP) field is simulated in the full toroidal geometry, under realistic plasma conditions in MAST experiments. The physics associated with several aspects of the RMP penetration—the plasma response and rotational screening, the resonant and non-resonant torques and the toroidal momentum balance—are highlighted. In particular, the plasma response is found to significantly amplify the non-resonant component of the RMP field for some of the MAST plasmas. A fast rotating plasma, in response to static external magnetic fields, experiences a more distributed electromagnetic torque due to the resonance with continuum waves in the plasma. At fast plasma flow (such as for the MAST plasma), the electromagnetic torque is normally dominant over the neoclassical toroidal viscous (NTV) torque. However, at sufficiently slow plasma flow, the NTV torque can play a significant role in the toroidal momentum balance, thanks to the precession drift resonance enhanced, so-called superbanana plateau regime.

共鳴磁場摂動(RMP)場の浸透ダイナミクスを、MAST実験における現実的なプラズマ条件下で、完全トロイダル幾何学においてシミュレーションした。RMP浸透のいくつかの側面に関連する物理——プラズマ応答と回転遮蔽、共鳴および非共鳴トルク、ならびにトロイダル運動量バランス——に焦点を当てる。特に、いくつかのMASTプラズマにおいて、プラズマ応答がRMP場の非共鳴成分を有意に増幅することが見出された。高速回転プラズマは、静的External磁場に応答して、プラズマ中の連続波との共鳴により、より広範囲に分布した電磁トルクを経験する。高速プラズマ流(MASTプラズマなど)では、電磁トルクが通常、新古典トロイダル粘性(NTV)トルクよりも支配的である。しかし、十分に遅いプラズマ流では、歳差運動ドリフト共鳴によって増強された、いわゆるスーパーバナナ・プラトー領域により、NTVトルクがトロイダル運動量バランスにおいて重要な役割を果たし得る。
