The m=1 internal kink mode in a toroidal plasma with a flat q-profile near q=1
Abstract
Ideal magnetohydrodynamic stability is studied using the energy principle. The equilibrium configuration is allowed to have a broad region with q close to unity. The minimization of the energy functional yields an implicit equation for the growth rate that can be solved by simple numerical means. The growth rate depends very sensitively on q. The conditions of highest growth rate are given.
