Kinetic Transport Simulation of ICRF Heating in Tokamak Plasmas

Abstract

The deviation of the distribution functions from the Maxwellian due to the interaction with waves affects the propagation and absorption of the wave itself. Therefore self-consistent analysis including the modification of the momentum distribution function is required for quantitative analysis of wave heating and current drive. The modeling code TASK was updated to describe the momentum distribution function of multi-species and the wave dielectric tensor for arbitrary momentum distribution function. Numerical results of ICRF heating in tokamak plasmas which generates energetic tail of distribution function are reported. © Springer 2010.
