等离子体的静态稳定性

本文讨论了外磁场微小的变动对等离子体平衡位形的影响,即等离子体的静态稳定性问题。指出,只有当附加磁场与等离子体接近不稳定边界的模相耦合时,才可能引起平衡位形很大的变化。由此,我们分析了杂散场对环电流器(托克马克)的影响。

THE STATIC STABILITY OF PLASMA

In this article, the effects of the small magnetic field perturbation on the equilibrium of plasma are discussed (the problem of the static stability of plasma). It is pointed out that a large variation in the equilibrium configuration may take place only when the small magnetic perturbations couple with the plasma modes which are almost neutally stable. Accordingly, the effects of the main classes of the stray field in Tokamak devices are analysed.
