Abstract

In specific cases the critical beta (j3c) for stability against internal magnetohydrodynamic (MHD) ballooning modes can be improved significantly by takinginto account the stabilizing influence of the ion diamagnetic drifts. This kinetic modification to the ideal MHD analysis and radial corrections to the local theory are included in a calculation of /3C as a function of toroidal mode number (n) for a particular tokamak equilibrium sequence of interest.
