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…
Measurement of zero-frequency fluctuations generated by coupling between Alfven modes in the JET tokamak
Juan Ruiz Ruiz, Jeronimo Garcia, Michael Barnes +13
We report the first experimental detection of a zero-frequency fluctuation that is pumped by an Alfvèn mode in a magnetically confined plasma. Core-localized bidirectional Alfvèn m…
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…
Gaussian process surrogate models for the properties of micro-tearing modes in spherical tokamaks
William Hornsby, Ander Gray, James Buchanan +9
Spherical tokamaks (STs) have many desirable features that make them a suitable choice for fusion power plants. To understand their confinement properties, accurate calculation of…
