Stabilization of MHD modes in an axisymmetric plasma column through the use of a magnetic divertor

B. Lane, R.S. Post, J. Kesner1987年被引用 44Nuclear FusionIF 3出版社

The introduction of a magnetic limiter is proposed for stabilization of MHD interchange modes in the central cell of a tandem mirror. The magnetic limiter creates a ring null in the magnetic field, and electrons which enter the null can stream azimuthally and thereby 'short-circuit' m = 1 fluctuations. This disallows a rigid m = 1 response and introduces finite Larmor radius stabilization effects in much the same way as they appear for higher azimuthal modes. Some pressure gradient can be maintained on the separatrix flux surface by locating the null on a local magnetic maximum. This scheme introduces the possibility of a fully axisymmetric tandem mirror.

タンデムミラー中央部におけるMHD不安定性モードの安定化のために、磁気リミッターの導入が提案されている。磁気リミッターは磁場中にリング状の零点を生成し、この零点に入った電子は方位角方向に流れることができ、それによってm=1の揺らぎを「短絡」させることができる。これにより、剛体的なm=1応答が妨げられ、より高次の方位角モードに見られるのと同様の有限ラーモア半径安定化効果がもたらされる。セパラトリックス面上に圧力勾配をある程度維持するには、磁場の極大点に零点を配置すればよい。この方式により、完全な軸対称タンデムミラーの実現可能性が示される。
