| Research Abstract |
It is very important to increase the plasma beta value for realization of the fusion reactor. We conducted a research on stabilization of resistive wall mode, which finally limit the beta value. The mechanism of RWM triggered by energetic driven mode has been clarified. Stabilization of RWM with very small and few coils has been clarified. However, under certain conditions, the degradation of plasma by 3D effect of sideband effect due to small size of the control coils has been observed.
