ALPHA PARTICLE ENERGY LOSSES INDUCED BY EXCITATION OF TOROIDICITY INDUCED ALFVEN EIGENMODES IN TOKAMAKS

摘要

The upper limit of the energy losses of alpha particles (V_ε) caused by destabilization of toroidicity induced Alfven eigenmodes (TAEs) in a reactor tokamak is evaluated. It is shown that the dependence of v_ε on Alfven velocity (v_A) can be non-monotonic, with sharp maxima at certain values of v_A .
