Modelling resonant field amplification due to low-n peeling modes in JET

Yueqiang Liu, S Saarelma, M P Gryaznevich, T C Hender, D F Howell, JET-EFDA contributors2010年Plasma Physics and Controlled FusionIF 2.2出版社

The MHD code MARS-F is used to model low-n, low-frequency, large-amplitude resonant field amplification peaks observed in JET low-pressure plasmas. The resonant response of a marginally stable, n = 1 ideal peeling mode is offered as a candidate to explain the experimental observation. It is found that, unlike the response of a stable resistive wall mode, the peeling mode response is not sensitive to the plasma rotation, nor to the kinetic effects.

MARSコードは、JET低圧力プラズマで観測された低次(n=1)、低周波数、大振幅の共鳴磁場増幅をモデル化するために使用される。限界安定なn=1理想ペアリングモードの共鳴応答が、実験観測を説明する候補として提示されている。安定な抵抗性壁モードの応答とは異なり、ペアリングモードの応答はプラズマ回転にも運動論的効果にも敏感ではないことが判明した。
