Abstract

Low-frequency stability of mirror confined plasmas is reviewed. Interchange, E×B rotation-driven and E×B drift shear-driven (Kelvin-Helmholtz) modes are studied based on the Rosenbluth-Simon equation. The flute stability of these modes in mirror confined plasmas is analyzed by use of Newcomb's FLR Lagrangian. E×B rotation-driven drift waves, several stabilization schemes for axisymmetric mirror plasmas including wall stabilization and RF stabilization, and rotational stability of theta-pinch plasmas are also briefly discussed.
