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) Snapshots of the mode structures for the multiple NAE–RSAE modes with n = 11 and m = (18;15) during the transition from the cascade modes to NAEs: from left to right are l = 0 even-type mode, l = 1 even-type modes, l = 0 odd-type mode, l = 1 odd-type modes. The values of nqmin for the snapshots are [(a1) and (a2)] nqmin ≈ 16.87; [(b1) and (b2)] nqmin ≈16.81; [(c1) and (c2)] nqmin ≈ 16.59; [(d1) and (d2)] nqmin ≈ 16.48. |
