The m=1 kink mode in a rotating tokamak plasma with anisotropic pressure

The m=1 internal kink mode is investigated in axisymmetric toroidal plasmas with poloidal and toroidal plasma flow and anisotropic pressure. The guiding centre model of the plasma is used to derive a dispersion relation that contains the full guiding centre distribution of the equilibrium. Due to kinetic damping, smaller growth rates are found than predicted by fluid theory. Pressure anisotropy is found to reduce the growth rate too, while toroidal rotation contributes to the destabilizing effect of the pressure gradient. (author) 5 refs
