Abstract

Monte Carlo operators for the interaction between rf waves and ions in a tokamak are derived. The operators are intended for orbit following codes that use an acceleration scheme, i.e., where one calculated orbit represents many real orbits. The derivation starts from an orbit averaged quasi-linear diffusion operator, and local Monte Carlo operators are obtained by formulating this operator for a special set of phase space variables. The resulting Monte Carlo operators include the effects of wave-induced transport in both velocity and real space. Furthermore, the operators are applicable to arbitrary axisymmetric geometry.
