The plasma response influence on the penetration of an external low frequency helical perturbation into a tokamak edge plasma has been studied on the basis of the two-fluid MHD equations in the linear approximation for the cylindrical model. Components of the penetrating field, the plasma flows, the perturbation current density distribution and the radial profile of the poloidal driven force density are found in the resonant region and investigated for the parameters of the TEXTOR-DED, CSTN-IV and HYBTOK-II tokamaks. Preliminary comparisons with the CSTN-IV and HYBTOK-II experiments are made and a good qualitative agreement has been found.
外部低周波ヘリカル摂動のトカマク周辺プラズマへの侵入に対するプラズマ応答の影響を、円柱モデルの線形近似における二流体MHD方程式に基づいて研究した。侵入場の成分、プラズマ流、摂動電流密度分布、およびポロイダル駆動力密度の動径分布を共鳴領域で求め、TEXTOR-DED、CSTN-IV、HYBTOK-IIトカマクのパラメータについて調査した。CSTN-IVおよびHYBTOK-IIの実験との予備的な比較を行い、良好な定性的一致が見出された。
