Tokamak formation and sustainment by coaxial helicity injection current drive

Experiments characterizing the coaxial helicity source and helicity injection current drive on the Prototype Helicity Injected Tokamak (Proto-HIT) have been performed. Toroidal currents over 30 kA can be sustained for times much greater than the plasma resistive time. The coaxial source operates with a large toroidal field that greatly enhances the source impedance, allowing a high rate of helicity injection (high source voltage) at a low source current (high efficiency), with results showing good agreement with a simple analytical model

同軸ヘリシティ源およびヘリシティ注入電流駆動の特性評価実験が、Prototype Helicity Injected Tokamak (Proto-HIT) において実施された。30 kA を超えるトロイダル電流は、プラズマ抵抗時間よりもはるかに長い時間にわたって維持され得る。同軸源は大きなトロイダル磁場で動作し、これにより源インピーダンスが大幅に増大し、低い源電流(高効率)で高いヘリシティ注入率(高い源電圧)が可能となる。結果は単純な解析モデルと良好な一致を示している。
