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.}, title = {Evaluation of Efficiency of Power Transferred from ICRF Fast Ions to Bulk Plasma Based on Orbit Following in Real Coordinates in LHD}, volume = {10}, year = {2015} }
