N2 - In our earlier work [Imadera et al. REDS Plasma Sci. Technol., 2016, 171, 52], the ion-temperature-driven modes were studied in the presence of radio frequency (RF) waves by the use of gyrokinetic simulation code. It was shown that the RF waves through the ponderomotive force can stabilize the ion-temperature-gradient instabilities and contrary to the usual belief no RF wave-induced flow generation hypothesis was required. This might be a major way to explain many unknowns in the space plasma and can also help to create a transport barrier in the fusion energy generation. In this work, we extend our earlier work to investigate the consequent transport and report the effect on the ion turbulent diffusivity.
