Stability of high-beta skin current Tokamaks to axially symmetric displacements
Abstract
The axisymmetric stability of skin-current models of elliptical and doublet-shaped Tokamaks is studied analytically in the high-beta, large-aspect-ratio limit. Stability is determined by the position of an outer conducting wall. The critical wall spacing for stability of these configurations is insensitive to the value of beta up to the equilibrium limit, but stability is enhanced for the skinned current profile used in these studies.
