The current generated by alpha-particle loss in tokamak reactors

It is shown that non-ideal confinement of alpha particles in tokamak reactors should result in the generation of a longitudinal current in the plasma. The distribution of this current along the radius is studied in the case of tokamaks with relatively good alpha-particle confinement, and its relationship with the plasma parameters established. It is found that when the current generated by the plasma particles flows in the direction opposite to that of the original current in the plasma, the initial current should exceed some critical value for the steady states to exist. If it does not, the alpha particles will lead to a drop in the current in the plasma.

トカマク炉におけるアルファ粒子の非理想的閉じ込めが、プラズマ中に長手方向の電流を生成するはずであることが示される。この電流の半径に沿った分布は、アルファ粒子の閉じ込めが比較的良好なトカマクの場合について研究され、そのプラズマパラメータとの関係が確立される。プラズマ粒子によって生成された電流が、プラズマ中の元の電流とは反対方向に流れる場合、定常状態が存在するためには初期電流が何らかの臨界値を超えなければならないことが見出される。もしそうでなければ、アルファ粒子はプラズマ中の電流の低下を引き起こす。
