The edge pressure gradient (H-mode pedestal) for computed equilibria in which the current density profile is consistent with the bootstrap current may not be limited by the first-regime ballooning limit. The transition to second stability is easier for higher elongation, intermediate triangularity, larger aspect ratio, pedestal at larger radius, narrower pedestal width, higher , and lower collisionality.
Miller et al. (Fri,) studied this question.
