Abstract
A novel technique is proposed for creating transport barriers by the rf waves. This is that the transport barriers can be created by the rf induced ponderomotive force itself and no rf induced flow shear generation is necessary. It is demonstrated that the ponderomotive force of the rf waves can stabilize the ion temperature gradient (ITG) mode, considered nowadays as the dominant source of anomalous energy losses in the low confinement (L) mode. It is also shown that this stabilization can be achieved for rather modest values of the rf power and hence should be easily obtained in actual experiments.
