Analysis of a spatial axis stellarator by numerical and analytical techniques

K. Ichiguchi, M. Wakatani1988年被引用 4Nuclear FusionIF 3出版社

The magnetohydrodynamic equilibrium, local stability, and transport properties of a spatial axis stellarator with circular cross-section are calculated by using a three-dimensional MHD code (BETA code). The equilibrium results are compared with analytic expressions given by Solov'ev and Shafranov to examine the applicability of the theory. Agreement is found with respect to the equilibrium properties, such as rotational transform, shift of magnetic axis due to finite pressure, and formation of a magnetic well. The toroidal effects on both curvature and torsion of the spatial magnetic axis must be estimated with sufficient accuracy so as to obtain agreement.

磁気流体平衡、局所安定性、および円形断面を有する空間軸ステラレーターの輸送特性を、三次元MHDコード(BETAコード)を用いて計算した。平衡結果は、Solov'evおよびShafranovによって与えられた解析式と比較し、理論の適用可能性を検討した。平衡特性、すなわち回転変換、有限圧力による磁気軸のシフト、および磁気井戸の形成に関して一致が見られた。一致を得るためには、空間磁気軸の曲率と捩率の両方に対するトロイダル効果を十分な精度で評価する必要がある。
