Abstract

A high-beta circular tokamak equilibrium with a large pressure gradient near the plasma edge is examined with respect to magnetohydrodynamic stability including external kink, tearing, and ballooning modes with and without line-tying effects. As the edge pressure gradient increases, the linear growth rate decreases and the mode spectrum broadens with the perturbation increasingly localized near the edge.
