Analysis of the nonlinear dynamics of a chirping-frequency Alfvén mode in a Tokamak equilibrium
Xin Wang, Sergio Briguglio, Claudio Di Troia +5
Chirping Alfvén modes are considered as potentially harmful in burning Tokamak plasmas. In this paper, the nonlinear evolution of a single-toroidal-number chirping mode is analysed…
Dynamics of reversed shear Alfvén eigenmode and energetic particles during current ramp-up
