Numerical Calculations of Localized Ideal and Resistive Instabilities in INTOR Equilibria

摘要

The stability of typical INTOR equilibria with respect to localized ideal and resistive instabilities is investigated. Configurations which are stable to ideal ballooning modes (and are therefore also Mercier stable) are shown to be unstable with respect to resistive ballooning instabilities, and the corresponding growth rates are calculated. A useful relation is given which allows calculation of the resistive growth rate at the ideal ballooning limit. This relation is also valid for three-dimensional equilibria. (ERA citation 13:042258)
