Abstract

A recent series of investigations on ion temperature gradient (ITG) drift instabilities based on multiscale gyrokinetic particle particle simulation have been carried out to address the questions concerning 1) the interactions between the global zonal flow modes and the mesoscale ITG turbulence, 2) the interplay between these instabilities and the resulting profile modifications and 3) the numerical noise issue in long time simulations. This purpose here is to review these results and to use them to shed some light on the question of steady state transport of ITG turbulence.
