摘要

We have shown that the ideal outer region uncoupled Δ′ solution alone is insufficient for determining the MHD stability of a tearing mode in toroidal geometry. Accurate equilibrium reconstructions are taken in this study, and qualitative agreement is found between the onset point of the mode (Figure Presented) in experiment and that in the analysis. All equilibria considered are ideal stable (including the 1/1 mode) despite the existence of a q=1 surface. This work supports the validity and relevance of classic resistive MHD stability theory of high temperature toroidal plasmas and can lead to testing various physics effects, in the inner layer and the outer region, on mode stability in comparison with experiment.
