Reducing turbulent transport in tokamaks by combining intrinsic rotation and the low momentum diffusivity regime
Haomin Sun, Justin Ball, Stephan Brunner +8
Based on the analysis of a large number of high-fidelity nonlinear gyrokinetic simulations, we propose a novel strategy to improve confinement in spherical tokamak plasmas by combi…
Physics of the low momentum diffusivity regime in tokamaks and its experimental applicability
Haomin Sun, Justin Ball, Stephan Brunner +9
Strong plasma flow shear is beneficial for reducing turbulent transport. However, traditional methods of driving flow shear do not scale well to large devices such as f…
A quasi-linear model of electromagnetic turbulent transport and its application to flux-driven transport predictions for STEP
M. Giacomin, D. Dickinson, W. Dorland +7
A quasi-linear reduced transport model is developed from a database of high- electromagnetic nonlinear gyrokinetic simulations performed with Spherical Tokamak for Energy Produc…
On the importance of parallel magnetic-field fluctuations for electromagnetic instabilities in STEP
D. Kennedy, C. M. Roach, M. Giacomin +8
[ABRIDGED] This paper discusses the importance of parallel perturbations of the magnetic-field in gyrokinetic simulations of electromagnetic instabilities and turbulence at mid-rad…
