| Outline of Final Research Achievements |
Stabilization of Resistive Wall Modes (RWMs) is a critical issue for advanced tokamaks since they limit the achievable beta value. In this study, we focus on the RWM stabilization by plasma rotation, and obtained the following findings: (1) centrifugal modification to MagnetoHydroDynamic (MHD) equilibrium brings about the RWM stabilization. (2) In rotating plasmas, the kinetic-MHD model should be generalized. The generalized kinetic-MHD model indicates that the rotation shear stabilizes the RWMs, which is qualitatively consistent with experimental results.
