Neoclassical MHD Equilibria in Low Aspect Ratio Reversed Field Pinch

Y. Nagamine

Abstract

The magnetohydrodynamic (MHD) equilibrium and local mode stability of a low aspect ratio reversed field pinch (RFP) plasma is studied. The dependences of the equilibrium and stability properties, and bootstrap current (BSC) profile on the plasma pressure profile, β value and cross sectional shape are investigated with a view of obtaining stable, high β and high BSC‐driven equilibria against high‐m localized Mercier mode. In addition, the neoclassical MHD RFP equilibria including bootstrap current effects are calculated self‐consistently and compared with the classical MHD equilibria.
