A Weakly Nonlinear Theory of Zonal-Flow Forcing in Gyrokinetic Turbulence
Georgia Acton, Eduardo Rodrìguez, Gareth Roberg-Clark +1
The forced generation of zonal flows by microinstability-driven turbulence is investigated within the framework of local gyrokinetic theory far from marginality. We use a numerical…

Ion temperature and density gradient driven instabilities and turbulence in Wendelstein 7-X close to the stability threshold
L. Podavini, A. Zocco, J. M. GarcÃa-Regaña +4
Electrostatic gyrokinetic instabilities and turbulence in the Wendelstein 7-X stellarator are studied. Particular attention is paid to the ion-temperature-gradient (ITG) instabilit…

The Kinetic Ion-Temperature-Gradient-driven instability and its localisation
Eduardo Rodriguez, Alessandro Zocco
We construct a description of Ion Temperature Gradient (ITG) driven localised linear modes which retains both wave-particle and magnetic drift resonant effects while capturing the…
