Overview of recent physics results from MAST

A Kirk, J Adamek, RJ Akers +160

New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion…

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…

Constraints on dynamo action in plasmas

P. Helander, M. Strumik, A. A. Schekochihin

Upper bounds are derived on the amount of magnetic energy that can be generated by dynamo action in collisional and collisionless plasmas with and without external forcing. A hiera…

Collisionality scaling of the electron heat flux in ETG turbulence

G J Colyer, A A Schekochihin, F I Parra +4

In electrostatic simulations of MAST plasma at electron-gyroradius scales, using the local flux-tube gyrokinetic code GS2 with adiabatic ions, we find that the long-time saturated…

A stringent limit on the amplitude of Alfvénic perturbations in high-beta low-collisionality plasmas

J. Squire, E. Quataert, A. A. Schekochihin

It is shown that low-collisionality plasmas cannot support linearly polarized shear-Alfvén fluctuations above a critical amplitude , where is…

Suppression of phase mixing in drift-kinetic plasma turbulence

J. T. Parker, E. G. Highcock, A. A. Schekochihin +1

Transfer of free energy from large to small velocity-space scales by phase mixing leads to Landau damping in a linear plasma. In a turbulent drift-kinetic plasma, this transfer is…
