Equilibrium magnetic fields and currents in a nonaxisymmetric torus: external magnetic fields in stellarators

S.V. Shchepetov, A.B. Kuznetsov1996年被引用 9Nuclear FusionIF 3出版社

The three dimensional (3-D) and axisymmetric (2-D) magnetic fields produced by currents flowing in plasmas that are confined in stellarators with a nearly planar geometrical axis are investigated. Using the Green's function method to solve the 3-D linear equation derived previously, a simple procedure is presented here to determine the structure of plasma induced external magnetic fields in stellarators. A detailed numerical analysis of the values of the external 3-D magnetic fields and their dependences on the plasma profiles is performed. Analytical formulas are derived that could be useful for estimations. The possibility of using the measurements of these fields for the experimental identification of the magnetohydrodynamic (MHD) equilibria is considered. Also discussed are some interesting aspects of the influence of the magnetic hump on the value of the Pursch-Schluter currents (that appear in recent Heliotron-E experiments) and the influence of different features of the vacuum magnetic field on the dipole component of plasma induced field is classified. The results of calculations related to the modern experiments are presented, and the case that may be typical for future experiments is also considered

恒星状配位器(ステラレーター)に閉じ込められたプラズマ中の電流によって生成される、ほぼ平面状の幾何学的軸を持つ3次元(3-D)および軸対称(2-D)磁場について調査した。以前に導出された3次元線形方程式を解くためにグリーン関数法を用いて、ステラレーターにおけるプラズマ誘起外部磁場の構造を決定する簡便な手順をここに提示する。外部3次元磁場の値と、それらのプラズマ分布への依存性について詳細な数値解析を行った。推定に有用となり得る解析的公式を導出した。これらの磁場の測定を、磁気流体力学(MHD)平衡の実験的同定に用いる可能性について考察した。また、最近のヘリオトロンE実験で現れるパーシュ・シュリューター電流の値に対する磁気ポテンシャルの影響という興味深い側面と、真空磁場の異なる特徴がプラズマ誘起磁場の双極子成分に及ぼす影響の分類についても議論した。現代の実験に関連する計算結果を示し、将来の実験で典型的となり得るケースについても考察した。
