摘要: The possibility of stabilizing ideal magnetohydrodynamical (MHD) instabilities by resistive walls and slow plasma rotation (rotation frequencies comparable to tearing growth rates) was proposed recently Finn [Phys. Plasmas 2, 3782 (1995)] on the basis cylindrical theory. In present paper we analyze toroidal effects (pressure gradients favorable averaged curvature) [Glasser et al., Phys. Fluids 18, 875 (1975)] this “resistive window.” It is found that in geometry window for distance wall from scales as S−1/3 (S ratio Alfvenic time scales) thus becomes very small large tokamaks. Other differences between theories mode stability are discussed.
