Stability of high beta tokamaks to ballooning modes

Abstract

Ballooning modes are ~ound to possess a second stable regime for igh beta. The range of unstable beta values depends on the details of the equilibrium, and in particular, on shear, which can be strongly stabilizing. nonet • •-1U> opart war pvpwtf « H Kttwnr et woric •paraMb) *• (Mud SUttiGotttinamt.
