Description

The stabilization conditions for the m/n = 2/1 tearing mode are considered. A suitable definition of the Δ' parameter for toroidal geometry is proposed. A general criterion for tearing mode stabilization by additional local current is derived for a pressureless plasma with arbitrary cross-section. The effect of finite island width on the stabilization is considered in cylindrical geometry. A numerical code for calculating Δ' is developed and applied to the ITER configuration. The 2/1 tearing mode demonstrates the opposite dependence of its stability margin on li and q0 with respect to the ideal modes. The necessary stabilization conditions for ITER plasmas are obtained numerically. (author). 3 refs, 2 figs
