| Research Abstract |
Effect of resonant magnetic perturbation on MHD instabilities has been investigated in the Large Helical Device. When the external magnetic perturbation field was applied to the plasma temporally, the magnetic island was formed when the perturbation exceeds a threshold. Experiments in the different magnetic shear configurations suggest that the threshold increased with the strength of the magnetic shear. Also, it was clarified that the island width was quite larger than the prediction.
