| Research Abstract |
This research analyzed numerically the MHD stability near plasma edge pedestal to identify the physics mechanism which is important to suppress or mitigate large amplitude edge localized mode(ELM), because this ELM will damage future large fusion reactors. As the result of this research, it was shown that plasma poloidal rotation plays an important role to suppress or mitigate ELM with the plasma toroidal rotation control, which is one of the promising ELM suppressing/mitigating methods confirmed experimentally.
