Resonant excitation of shear Alfvén perturbations by trapped energetic ions in a tokamak

A new analytic expression is derived for the resonant drive of high n Alfvénic modes by particles accelerated to high energy by ion cyclotron resonance heating. This derivation includes finite orbit effects, and the formalism is completely nonperturbative. The high-n limit is used to calculate the c...
