Abstract

In order to optimize the transferred power efficiency from ICRF fast ions to bulk plasma, we have developed a code in which models of behaviors of ICRF fast ion are minimally adopted in order to save calculation time. A tendency of the transferred power efficiencies evaluated by the developed code is almost the same as that evaluated from the full analyses. In the regime with low efficiency of transferred power, the effect of the position of the resonance layer is large. The efficiency of the resonance layer through the point near the magnetic axis is found to be smaller than that of the typical ICRF resonance layer.
