Saturation of magnetised plasma turbulence by propagating zonal flows
Richard Nies, Felix Parra, Michael Barnes +2
Strongly driven ion-scale turbulence in tokamak plasmas is shown to be regulated by a new propagating zonal flow mode, the toroidal secondary mode, which is nonlinearly supported b…

Direct Microstability Optimization of Stellarator Devices
R. Jorge, W. Dorland, P. Kim +4
Turbulent transport is regarded as one of the key issues in magnetic confinement nuclear fusion, both for tokamaks in stellarators. In this work, we show that a significant decreas…

GX: a GPU-native gyrokinetic turbulence code for tokamak and stellarator design
N. R. Mandell, W. Dorland, I. Abel +4
GX is a code for solving the nonlinear gyrokinetic system for low-frequency turbulence in magnetized plasmas, particularly tokamaks and stellarators. In GX, our primary motivation…
