Quantitative comparison of experimental and theoretical growth rates of the positional instability in Double III

H. Yokomizo, F.W. McClain, T.H. Jensen1983年被引用 2Nuclear FusionIF 3出版社

Experimentally measured growth rates of the positional instability of vertically elongated plasmas in Doublet III are compared with those obtained from a numerical code based on linear perturbation theory. The relevant elements of the circumstances of the experiment have been included in the code. The perturbations of plasma currents and currents in the wall of the vacuum vessel as well as in the coils surrounding the plasma are included in the model. The modelling of the complicated external circuitry of the coils is based on a simple assumption which was supported by observation. Comparison of the measured growth rates with those calculated suggests that the essential phenomena are adequately described by the model.

実験的に測定されたDoublet IIIにおける垂直方向に伸長したプラズマの位置不安定性の成長率を、線形摂動理論に基づく数値コードから得られた成長率と比較した。実験の状況に関連する要素はコードに含められている。プラズマ電流、真空容器壁内の電流、ならびにプラズマを囲むコイル内の電流の摂動がモデルに含まれている。コイルの複雑な外部回路のモデル化は、観測によって支持された単純な仮定に基づいている。測定された成長率と計算された成長率の比較は、本質的な現象がモデルによって適切に記述されていることを示唆している。
