Description

The anomalous radial transport considerably affects the rf current-drive efficiency and the driven-current profile. In this paper, starting from the Fokker-Planck equation in the presence of anomalous radial transport, we derive a radial diffusion-like equation for the rf-driven current density. This equation can be solved by modeling the anomalous transport and the density profile. The anomalous effects on ECCD are also studied by incorporating our method into a ray tracing code.
