A general analytical theory for the two-dimensional eigenmode structures and stability of high toroidal-mode-number (high-n) shear Alfvén modes in axisymmetric tokamaks is presented. This theory, thus, further generalizes the previous work on the high-n toroidal Alfvén eigenmode (TAE) [Phys. Fluids B 5, 3668 (1993)] by including, nonperturbatively, plasma kinetic effects and resonant excitations by energetic particles. Specifically, in addition to recovering the known theoretical predictions on TAE, we have derived new results on global radial structures, as well as stability properties of kinetic toroidal Alfvén eigenmodes (KTAE) and energetic-particle modes (EPM). © 1996 American Institute of Physics.
