Anisotropic resistivity effects on the minimum dissipation states of tokamak plasmas sustained by coaxial helicity injection

K I Caputi, Ricardo Farengo2001年Plasma Physics and Controlled FusionIF 2.2出版社

The minimum dissipation states of a tokamak-like plasma sustained byhelicity injection are determined. The Ohmic energy dissipation rate isminimized using the helicity balance as a constraint and consideringdifferent resistivity values in the directions parallel and perpendicularto the magnetic field inside the plasma. The resulting Euler-Lagrangeequations are solved, assuming axial symmetry, for different values of theratio between the parallel and perpendicular resistivities(η∥/η⊥). It is shown that previously publishedresults are not completely correct and that the radial profile of µ0jφ/Bφ (the ratio between the toroidal current densityand the toroidal magnetic field) changes significantly whenη∥/η⊥ decreases.

ヘリシティ注入によって維持されるトカマク類似プラズマの最小散逸状態が決定される。オームエネルギー散逸率は、ヘリシティバランスを制約として用い、プラズマ内部の磁場に平行および垂直な方向の異なる抵抗率を考慮して最小化される。得られたオイラー=ラグランジュ方程式は、軸対称を仮定し、平行および垂直抵抗率の比(η∥/η⊥)の異なる値に対して解かれる。以前に発表された結果が完全には正しくないこと、およびη∥/η⊥が減少するとµ0jφ/Bφ(トロイダル電流密度とトロイダル磁場の比)の動径方向プロファイルが大きく変化することが示される。
