Abstract

Localized resistive modes (resistive interchange and resistive ballooning modes) are investigated for self-consistent Tokamak equilibria which have circular cross-sections near the magnetic axis. The second region of stability (which is stable with respect to ideal ballooning modes at high poloidal beta beta-p proves to be unstable when resistive effects are taken into account as well. In the low beta-p stability region, the stability boundaries are shifted toward lower beta-p values. The magnitude of the shift depends on the degree of localization of the perturbation around the field line, highly localized perturbations being the most unstable ones.
