Gyrokinetic Simulation of Ion-Temperature-Gradient Mode in the presence of Radio-Frequency Waves
POSTER
Abstract
In our earlier work (REDS Plasma Science and Technology,171, 52 (2016)) the ion temperature
driven modes was studied in the presence of radio frequency waves by the use of Gyro-Kinetic simulation
Code. It was shown that the radio frequency waves through the ponderomotive force can stabilize the ion
temperature gradient instabilities and contrary to the usual belief no radio frequency 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.
