Transition to the H-mode by energetic electrons

K. Itoh, S.-I. Itoh1992年被引用 19Nuclear FusionIF 3出版社

The effect of electron loss due to the toroidal ripple on the H-mode transition is studied. When energetic electrons exist in tokamaks, for example in the case of electron heating by lower hybrid (LH) waves, the edge electric field may exhibit bifurcation to more positive values. In this state, both the electron loss and the ion loss (such as direct orbit loss) are reduced. The criterion for the transition is derived. Comparison with the H-mode in JT-60 LH plasma shows qualitative agreement

トロイダル・リップルによる電子損失がHモード遷移に及ぼす影響について研究した。トカマクにおいて高エネルギー電子が存在する場合、例えば低域混成(LH)波による電子加熱の場合、エッジ電場はより正の値への分岐を示すことがある。この状態では、電子損失とイオン損失(直接軌道損失など)の両方が低減される。この遷移の条件が導出された。JT-60のLHプラズマにおけるHモードとの比較は、定性的な一致を示している。
