Zonal-flow generation and saturation of electromagnetic ion-scale turbulence in tokamaks
Y. Zhang, T. Adkins, M. Barnes +5
Local flux-tube gyrokinetic simulations of ion-scale turbulence in tokamak plasmas at finite plasma beta are conducted to investigate the generation of zonal flows via turbulent st…
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…
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 Produc…
