Abstract

Monte-Carlo operators are constructed for the orbit-averaged Fokker-Planck equation describing collisions and wave-particle interaction. Special emphasis is placed on ion cyclotron resonance heating of tokamaks, but the results are applicable to general quasilinear processes in arbitrary magnetic configurations in which particle motion is integrable. All effects of non-standard orbit topology, such as large orbit widths, are fully taken into account. The Monte Carlo operators may be used for simulating, for example, neoclassical transport, radio-frequency heating, and wave-driven spatial diffusion.
