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…
Asymptotic scaling theory of electrostatic turbulent transport in magnetised fusion plasmas
T. Adkins, I. G. Abel, M. Barnes +8
Turbulent transport remains one of the principal obstacles to achieving efficient magnetic confinement in fusion devices. Two of the dominant drivers of the turbulence are microsca…
The gyrokinetic field invariant and electromagnetic temperature-gradient instabilities in `good-curvature' plasmas
P. G. Ivanov, P. Luhadiya, T. Adkins +1
Curvature-driven instabilities are ubiquitous in magnetised fusion plasmas. By analysing the conservation laws of the gyrokinetic system of equations, we demonstrate that the well-…
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…
