Abstract

The full wave TORIC code and the Kinetic Fokker-Planck SSFPQL code are com- bined to perform self-consistent simulations of the ICRF heating in the EAST 2D magnetic config- uration. The combined package is applied to the ICRF hydrogen minority heating in a deuterium plasma with the hydrogen concentration up to 10%. The fast wave propagation and absorption properties, power partitions among the plasma species and the RF driven energetic tails have been analyzed. Meanwhile, in order to optimize the ICRF heating, changing the resonance locations has also been considered in EAST plasmas.
