Toroidal kink mode at finite beta

A. D. Turnbull

Abstract

The free-boundary toroidal kink mode is compared with the internal kink mode for a finite beta, circular crosssection toroidal equilibrium. The toroidal kink is more unstable than the ideal internal kink in the sense that the unstable parameter range of the toroidal kink is more extensive. Moreover, when both modes are unstable, the growth rate of the toroidal kink is generally several times larger than that of the ideal internal kink.
