| Research Abstract |
We have analyzed stabilization mechanism and interaction with other MHD modes for resistive wall mode (RWM) that could limit the achievable pressure in fusion reactors. In particular, we have compared results between JT-60U and DIII-D tokamaks, then it is clarified that new instability driven by energetic ions can trigger RWM despite enough plasma rotation for RWM stabilization.
