Scaling laws for the cutoff wavenumber of the short-wavelength ion-temperature-gradient mode in a Z-pinch
O. Gupta, M. Barnes, F. I. Parra +4
We use a heuristic fluid model to predict the dependence of the cutoff wave number for the short-wavelength ion temperature gradient (SWITG) mode on ion density gradient, ion tempe…
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…
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…
Optimisation of Gyrokinetic Microstability Using Adjoint Methods
Georgia Acton, Michael Barnes, Sarah Newton +1
Microinstabilities drive turbulent fluctuations in inhomogeneous, magnetized plasmas. In the context of magnetic confinement fusion devices, this leads to an enhanced transport of…
