A computer model of radial transport in tokamaks

A multi-regime model of radial particle and energy transport in tokamaks, based on the predictions of low-frequency microinstability theory, has been incorporated into a one-dimensional computer code. The code also includes background neutral gas, neoclassically (3-regime) diffusing impurity ions, adiabatic compression, and self-consistent neutral-injection heating by means of the slowing down of beam ions. A reasonable measure of agreement with experimental results from a number of present-day tokamak devices is achieved. Computations for larger next-generation tokamaks emphasize the problem of high-Z metallic impurities, and a "cold plasma blanket" technique for their control is presented.

トカマクにおける径方向粒子・エネルギー輸送の多領域モデルが、低周波微不安定性理論の予測に基づいて、一次元計算機コードに組み込まれた。このコードにはまた、背景中性ガス、新古典的(3領域)拡散を起こす不純物イオン、断熱圧縮、およびビームイオンの減速による自己無撞着な中性粒子入射加熱も含まれている。現在の複数のトカマク装置における実験結果との合理的な一致が達成された。次世代の大型トカマクに関する計算は、高Z金属不純物の問題を強調しており、その制御のための「冷プラズマブランケット」手法が提示される。
