High poloidal beta (βp approximately 5) discharges produced with nearly balanced tangential neutral beam injection into low current discharges in the TFTR tokamak are described. As βp exceeds approximately 1.2 times the aspect ratio, a separatrix with an inside poloidal field null is observed to limit the outer boundary of the plasma. Since the curvature of TFTR's applied vertical field is constant, the appearance of the poloidal field null corresponds to the equilibrium poloidal beta limit

日本語訳

高ポロイダルベータ(βp約5)の放電は、TFTRトカマクにおける低電流放電へのほぼバランスの取れた接線方向中性粒子ビーム入射によって生成され、その特性が記述されている。βpがアスペクト比の約1.2倍を超えると、内側ポロイダル磁場ヌルを伴うセパラトリックスがプラズマの外側境界を制限することが観測される。TFTRに印加される垂直磁場の曲率は一定であるため、ポロイダル磁場ヌルの出現は平衡ポロイダルベータ限界に対応する。
