Resistive ballooning modes near the edge of toroidal configurations
In this paper the resistive ballooning mode equations are cast in a new form appropriate for evaluation near the plasma edge of toroidal (axisymmetric as well as three-dimensional) configurations, where the resistive ballooning effects out-weigh the diamagnetic effects. Explicit evaluation is carried out for cylindrically symmetric plasmas and for a tokamak model with circular cross-sections. Owing to the large electric resistivity of the regions considered, resistive ballooning modes with growth rates comparable to the characteristic growth rate of ideal ballooning modes are possible.
