Stability properties of kink-interchange modes in a plasma containing alpha particles
Abstract
The linear and nonlinear stability properties of pressure driven electromagnetic interchange modes are investigated in the presence of a transverse current gradient. Possibilities for both stabilization and destabilization are obtained. The influence of nonlinear mode interactions is considered and explosively unstable situations are found. The influence of injected ions and fusion generated alpha particles are also discussed. In particular it is demonstrated for a slab geometry that the curvature drift of fusion generated alpha particles is not serious for the stability.
