Zonally dominated dynamics and the transition to strong turbulence in ion-scale plasma turbulence
- Abstract:
-
We present a study of the low-transport Dimits state (Dimits et al., 2000) and the transition to a high-transport saturated state in plasma turbulence driven by the ion-temperature-gradient instability. This thesis focuses on a fluid model derived in the cold-ion, long-wavelength asymptotic limit of the ion gyrokinetic equation in a magnetic field with constant curvature (a Z-pinch) and in the presence of an equilibrium temperature gradient. Numerical simulations reveal that the Dimits sta...
