文摘The internal kink mode with a real frequency comparable with the bulk ion diamagnetic frequency is investigated in the case of lower hybrid wave injection.It is found that circulating supra-thermal electrons can directly destabilize the internal kink mode by resonance interaction in the neighborhood of the q =1 rational surface.The pressure gradient of circulating supra-thermal electrons on the resonance surface is crucial for excitation of the mode.
