Fokker-Planck equation in the presence of anomalous diffusion

Creators

Description

Spatial and temporal evolution of the distribution function is theoretically discussed in the presence of the rf waves and microscopic fluctuations. Using the quasilinear formulation, Fokker-Planck equation is derived in terms of the parallel and perpendicular energies and the distance across the magnetic surface. The energy dependence of the anomalous spatial diffusion term is studied for the case of the drift wave fluctuations. Cases for the intense ICRF heating is also discussed. (author)
