ON CONTROLLED FUSION AND PLASMA HEATING
The energy principle is used to study the ideal MHD stability of the m=1 internal kink mode in a toroidal plasma. 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 examples that we present retain the essential features of experimentally expected q-profiles. We find that the growth rate depends very sensitively on q when q is very close to unity. The highest growth rates are of the order epsilon/tau-"rm A", where tau-"rm A" is the poloidal Alfv'en time.
