| Outline of Final Research Achievements |
It is very important to stabilize resistive wall mode (RWM), which finally limits the beta value, in order to increase the plasma beta value for realization of the fusion reactor. We conducted a research on the effect of the external RWM stabilization coil on three dimensional equilibrium. We reconstructed the plasma for RWM stabilization experiment by RWM control coil with three dimensional equilibrium code. We indicated that the side band effect of the small JT-60SA RWM coils is not negligible and it can be evaluated by three dimensional equilibrium codes.
