Abstract

The frequency spectrum of tearing modes is analysed with the help of a mode coupling model, including toroidal effects in the MHD regions and various non linear effects in the resonant layers. In particular it is shown that the sudden damping of the mode rotation and the simultaneous enhancement of the growth rate observed in tokamaks can be explained as a bifurcating solution of the dispersion equation.
