Abstract

The bounce-averaging procedure for the electron Fokker-Planck equation is extended to the case of nonaxisymmetric geometry, in order to calculate consistently electron ripple-induced losses in tokamak during rf heating and current drive experiments. New explicit expressions for the bounce-averaged coefficients are developed for circulating electrons but also for banana electrons. While the effect of magnetic ripple is fairly negligible for circulating electrons, nonaxisymmetric corrections become significantly larger for banana electrons as compared to the axisymmetric case.
