Role of nonlinear toroidal coupling in electron temperature gradient turbulence

Global gyrokinetic particle simulation and nonlinear gyrokinetic theory find that electron temperature gradient sETGd instability saturates via nonlinear toroidal coupling, which is a nonlocal interaction in the wave vector space that transfers energy successively from unstable modes to damped modes preferentially with lower toroidal mode numbers. The electrostatic ETG turbulence is dominated b...

Magnetic Reconnection in Toroidal hi Mode Turbulence

Based on three-dimensional simulations of the Braginskii equations we show that for typical plasmaedge parameters the saturation of electromagnetic toroidal hi mode turbulence is controlled by the selfgeneration and subsequent annihilation of radial magnetic field perturbations. This should be contrasted with the electrostatic limit, where the growth of the linear hi mode is terminated by the o...
