Zonal-flow generation and saturation of electromagnetic ion-scale turbulence in tokamaks
Y. Zhang, T. Adkins, M. Barnes +5
The paper uses local gyrokinetic simulations to study how electromagnetic ion‑scale turbulence in tokamaks generates zonal flows, finding that a combined parameter β_eff = q²β_e co…
Suppression of temperature-gradient-driven turbulence by sheared flows in fusion plasmas
P. G. Ivanov, T. Adkins, D. Kennedy +3
Starting from the assumption that saturation of plasma turbulence driven by temperature-gradient instabilities in fusion plasmas is achieved by a local energy cascade between a lon…
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 Produ…
shear suppression of microtearing based transport in spherical tokamaks
B. S. Patel, M. R. Hardman, D. Kennedy +3
Electromagnetic microtearing modes (MTMs) have been observed in many different spherical tokamak regimes. Understanding how these and other electromagnetic modes nonlinearly satura…
