Abstract
The axially symmetric stability of skin current models of elliptical and doublet-shaped tokamaks is studied analytically in the high-β, 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 β up to the equilibrium limit; but stability is enhanced for the skinned current profile used in these studies.Keywords
