Edge MHD stability analysis for suppressing giant edge localized modes

本研究对等离子体边缘基座附近的MHD稳定性进行了数值分析，以确定抑制或缓解大幅度边缘局域模式(ELM)的物理机制，因为这种ELM将破坏未来的大型聚变反应堆。研究结果表明，通过等离子体环向旋转控制，等离子体极向旋转对抑制或缓解椭圆偏振起着重要的作用，这是一种很有前途的抑制/缓解椭圆偏振的方法。

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.
