Abstract
A plasma confined in a dipole field exhibits unique equilibrium and stabili ty properties. In particular, equilibria exist at all beta values and these equilibria are found to be stable to ballooning modes when they are interc hange stable. When a kinetic treatment is performed at low beta, a drift te mperature gradient mode is also found which couples to the MHD mode in the vicinity of marginal interchange stability.
