Drift Resistive Interchange and Tearing Modes in Cylindrical Geometry.

Abstract

Resistive interchange and tearing modes are studied including the effects of electron parallel pressure gradient and ion polarization drift (Hall terms) as well as finite plasma compressibility and perpendicular resistivity. It is found that for unfavorable curvature and weak tearing forces (positive but small delta) all modes are stabilized provided the effects of the Hall (drift) terms are large enough. The principal stabilizing influences are plasma compression and coupling to outgoing drift waves. The relevance to reversed field pinch and spheromak experiments is discussed. (Author)
