Abstract

There is increasing evidence, both from experiments and numerical simulations, that coupling and interaction between tearing modes play important roles during tokamak disruptions. The non-linear evolution of tearing modes with multiple rational surfaces is discussed in this paper. It is demonstrated that, in the presence of small differential rotation, the non-linear growth might be faster than exponential. This growth occurs as the rotation frequencies of the plasma at the different rational surfaces equilibrate.
