Nonlinear saturation of reversed shear Alfven eigenmode via high-frequency quasi-mode generation
Zhiwen Cheng, Guangyu Wei, Lei Ye +1
A nonlinear saturation mechanism for reversed shear Alfven eigenmode (RSAE) is proposed and analysed, and is shown to be of relevance to typical reactor parameter region. The satur…
