Toroidal equilibrium with low-frequency wave-driven currents

D.A. Ehst1985年被引用 15Nuclear FusionIF 3出版社

In the absence of an emf, the parallel current, j||, in a steady-state tokamak will consist of a neoclassical portion plus a wave-driven contribution. Using the drift kinetic equation, the quasi-linear (wave driven) current is computed for high-phase-speed waves in a torus, and this is combined with the neoclassical term to obtain the general expression for the flux surface average ⟨j||B⟩. For a given pressure profile this technique fully determines the MHD equilibrium, permitting the study of a new class of toroidal equilibria.

起電力がない場合、定常トカマクにおける平行電流j||は、新古典的項と波動駆動項から構成される。ドリフト運動論的方程式を用いて、トーラス内の高位相速度波に対する準線形(波動駆動)電流を計算し、これを新古典的項と組み合わせて、磁束表面平均⟨j||B⟩の一般式を得る。与えられた圧力分布に対して、この手法はMHD平衡を完全に決定し、新しいクラスのトロイダル平衡の研究を可能にする。
