Resistive ballooning modes in the second region of stability

Jin‐Yong Kim, Duk‐In Choi

Open publisher page 10 citations

Abstract

A recent study suggested that the resistive ballooning modes are largely stable in the second region of the ideal ballooning stability, unlike in the first region. This problem is reexamined here by numerically solving the full resistive mode equation. It is shown that in the second region there are unstable resistive ballooning modes with larger growth rates compared to those in the first region. This behavior is shown to be caused by the fact that the curvature force significantly influences the dynamics in the resistive region, and the mode is mainly driven unstable from the resistive region and not from the ideal region through Δ′.
