A quasi-isodynamic stellarator with poloidally closed contours of the magnetic field strength B (Mikhailov 2002 Nucl. Fusion42 L23) has been obtained by an integrated physics optimization comprising MHD and neoclassical theory. For a configuration with six periods and aspect ratio approximately 12, a main result is the attainability of an essentially MHD-stable high-β (⟨ β⟩ ≈ 0.085) plasma with low neoclassical transport, approximately vanishing bootstrap current in the long-mean-free-path regime and excellent α-particle confinement.

準等力学ステラレーターであって、磁場強度Bのポロイダル方向に閉じた等高線を持つもの(Mikhailov 2002 Nucl. Fusion42 L23)が、MHD理論と新古典理論からなる統合的物理最適化によって得られた。周期数6、アスペクト比約12の配位について、主な結果は、本質的にMHD安定な高β(⟨β⟩≈0.085)プラズマが達成可能であり、かつ新古典輸送が小さく、長平均自由行程領域においてブートストラップ電流がほぼ消滅し、α粒子閉じ込めに優れることである。
