Numerical simulation of the multiple reversed shear Alfvén eigenmodes associated with the trianuglarity Alfvén gap Project supported by the National Natural Science Foundation of China (Grant No. 11675222). |
(color online) (a) The q-profile with parameters: q(0) = 1.90, q(1) = 1.95, q′(0) = –0.5, and q′(1) = 0.5. (b) The density profile is chosen to be ρ = (1.00001 − αypρ)aρ, where α = 0.9, pρ = 1.1, aρ = 0.1. |
