Numerical and diagnostic extensions to the gyrokinetic code stella
Sven Stroteich, Georgia Acton, Michael Barnes +2
Understanding turbulence in magnetised plasmas requires robust numerical tools capable of capturing complex free-energy transfer processes across scales. We demonstrate the utility…
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…
Influence of the density gradient on turbulent heat transport at ion-scales: an inter-machine study with the gyrokinetic code stella
H Thienpondt, JM García-Regaña, I Calvo +2
Efficient control of turbulent heat transport is crucial for magnetic confinement fusion reactors. This work discusses the complex interplay between density gradients and micro-ins…
Optimisation of Gyrokinetic Microstability Using Adjoint Methods
Georgia Acton, Michael Barnes, Sarah Newton +1
Microinstabilities drive turbulent fluctuations in inhomogeneous, magnetized plasmas. In the context of magnetic confinement fusion devices, this leads to an enhanced transport of…
