Energetic particles stimulating macro-scale zonal flow generation in ion-temperature-gradient turbulence
We report a formation mechanism of macro-scale zonal flow (ZF) in ion-temperature-gradient (ITG) turbulence. Through gyro-kinetic simulations, it is found that the guiding centers of theenergetic particles (EPs) open a new dynamical coupling regime (∼a few EP gyro-radius) between the ITG turbulence...
