The kinetic effects influencing the stability of the resistive wall mode (RWM) are investigated by applying a drift kinetic code to calculate the change in the potential energy of the mode in the presence of thermal and energetic particles. The analysis is carried out for typical JET high-β plasmas. It is found that the strongest kinetic damping of the RWM arises due to mode resonance with the precession motion of the trapped thermal particles. The stability of the RWM in JET plasmas is also probed by using active MHD spectroscopy. The frequency spectrum of the plasma response to oscillating externally applied fields has been measured and fitted to parameter models in order to infer the stability of the RWM. A new model retaining information about the plasma response is presented to describe the resonant field amplification in the presence of a stable RWM.

抵抗性壁モード(RWM)の安定性に及ぼす運動論的効果を調査するため、ドリフト運動論コードを適用し、熱粒子および高エネルギー粒子の存在下でのモードのポテンシャルエネルギーの変化を計算した。解析は典型的なJET高βプラズマに対して実施された。その結果、RWMの最も強い運動論的減衰は、捕捉熱粒子の歳差運動とのモード共鳴に起因することが見出された。さらに、JETプラズマにおけるRWMの安定性は、能動的MHD分光法を用いても調査された。外部から印加された振動磁場に対するプラズマ応答の周波数スペクトルを測定し、パラメータモデルへのフィッティングを行うことにより、RWMの安定性を推定した。安定なRWMの存在下での共鳴磁場増幅を記述するため、プラズマ応答の情報を保持した新しいモデルを提示した。
