Zonally dominated dynamics and Dimits threshold in curvature-driven ITG turbulence
P. G. Ivanov, A. A. Schekochihin, W. Dorland +2
The saturated state of turbulence driven by the ion-temperature-gradient instability is investigated using a two-dimensional long-wavelength fluid model that describes the perturbe…
Ion-scale turbulence in MAST: anomalous transport, subcritical transitions, and comparison to BES measurements
F. van Wyk, E. G. Highcock, A. R. Field +4
We investigate the effect of varying the ion temperature gradient (ITG) and toroidal equilibrium scale sheared flow on ion-scale turbulence in the outer core of MAST by means of lo…
Symmetry breaking in MAST plasma turbulence due to toroidal flow shear
M. F. J. Fox, F. van Wyk, A. R. Field +3
The flow shear associated with the differential toroidal rotation of tokamak plasmas breaks an underlying symmetry of the turbulent fluctuations imposed by the up-down symmetry of…
Experimental determination of the correlation properties of plasma turbulence using 2D BES systems
M. F. J. Fox, A. R. Field, F. van Wyk +3
A procedure is presented to map from the spatial correlation parameters of a turbulent density field (the radial and binormal correlation lengths and wavenumbers, and the fluctuati…
Transition to subcritical turbulence in a tokamak plasma
F. van Wyk, E. G. Highcock, A. A. Schekochihin +3
Tokamak turbulence, driven by the ion-temperature gradient and occurring in the presence of flow shear, is investigated by means of local, ion-scale, electrostatic gyrokinetic simu…
