Widths of magnetic islands induced by finite plasma pressure are computed for the Heliotron-E configuration Phys. Rev. Lett. 53, 2242 (1984); Nucl. Fusion 27, 895 (1987). Equilibrium beta limits are obtained from the criterion of island overlap. Earlier experimental observations on internal disruptions in Heliotron-E are revisited.
Nakamura et al. (1990) studied this question.
