In this paper, the stability features of discrete Alfvén eigenmodes (αTAEs) trapped by the α-induced potential wells are explored in CFETR (China Fusion Engineering Test Reactor) advanced steady-state operation, where α denotes a measure of the pressure gradient. For the reversed magnetic shear (RS) H-mode scenario with enhanced internal transport barrier (ITB), the αTAEs are trapped in the electron cyclotron (EC) power deposition region and effects of different pedestals on αTAEs are analysed. For the negative off-axis magnetic shear scenario, the αTAEs are discussed, and the effect of different magnetic shears on the αTAEs is presented. Finally, the effect of beam energies and pitch-angle distributions on αTAE stability is also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
