Description
Understanding the triggering and regulation mechanisms of energetic particle (EP) transport is a significant issue for magnetically confined plasmas. Toroidal Alfven eigenmode (TAE) can be driven unstable by EPs intrinsically existed in burning plasmas [1]. Nonlinear generation of zonal flows (ZFs) is a significant component for TAE self-regulation. Previous studies contain only effects of EPs [2] or only thermal plasma nonuniformity. Thus, in this work, both effects are retained to get a more comprehensive evaluation of saturation level of ZF using both analytical theory and ORB5 simulation.
