Theory of toroidal Alfven modes excited by energetic particles in tokamaks
- Department of Physics and Astronomy, University of California, Irvine, California 92717-4575 (United States)
A general analytical theory for the two-dimensional eigenmode structures and stability of high toroidal-mode-number (high-{ital n}) shear Alfven modes in axisymmetric tokamaks is presented. This theory, thus, further generalizes the previous work on the high-{ital n} toroidal Alfven eigenmode (TAE) [Phys. Fluids B {bold 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 Alfven eigenmodes (KTAE) and energetic-particle modes (EPM). {copyright} {ital 1996 American Institute of Physics.}
