Abstract

The author presents a complete set of equations for the numerical simulation of ion cyclotron heating of tokamak plasmas. The model includes the full geometry of the tokamak equilibrium, full parallel dispersion, and perpendicular dispersion to second order in the Larmor radius. It is therefore capable of describing correctly ion cyclotron damping at the fundamental and first harmonic, as well as mode conversion to the ion Bernstein wave and/or the shear Alfven wave, depending on the heating scenario. It includes also electron magnetic pumping and Landau damping, the latter to lowest order in m-e/m-i. Relying on the knowledge gained from slab and ray tracing analysis, we also situate with respect to this standard model some of the further approximations which are commonly encountered in the literature. Finally, two procedures for the numerical solution of the standard model are proposed.
