Effect of RF Waves on Ion Temperature Gradient Modes

ORAL

Abstract

The ion-temperature-driven modes are studied in the presence of radio frequency waves by the use of the Gyro-Kinetic simulation Code and ASTRA Code. It is 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 is required. This might be a major way to create a transport barrier in the fusion energy generation.
