Intermittency of density fluctuations and zonal-flow generation in MAST edge plasmas
A. Sladkomedova, I. Cziegler, A. R. Field +5
The properties of the edge ion-scale turbulence are studied using the beam emission spectroscopy (BES) diagnostic on MAST. Evidence of the formation of large-scale high-amplitude c…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
Direct Gyrokinetic Comparison of Pedestal Transport in JET with Carbon and ITER-Like Walls
D. R. Hatch, M. Kotschenreuther, S. M. Mahajan +8
This paper compares the gyrokinetic instabilities and transport in two representative JET pedestals, one (pulse 78697) from the JET configuration with a carbon wall (C) and another…
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…
Quantifying noise sources in the KSTAR 2014 Thomson Scattering system from the measured variation on electron temperature
Tae-suk Oh, K. H. Kim, J. H. Lee +6
With the Thomson scattering (TS) system in KSTAR, temporal evolution of electron temperature () is estimated using a weighted look-up table method with fast sampling ( o…
Measurement of high-k density fluctuation wavenumber spectrum in MAST and Doppler backscattering for spherical tokamaks
J. C. Hillesheim, N. A. Crocker, W. A. Peebles +7
The high-k () wavenumber spectrum of density fluctuations has been measured for the first time in MAST [B. Lloyd et al, Nucl. Fusion 43, 1665 (…
Experimental Signatures of Critically Balanced Turbulence in MAST
Y. -c. Ghim, A. A. Schekochihin, A. R. Field +8
Beam Emission Spectroscopy (BES) measurements of ion-scale density fluctuations in the MAST tokamak are used to show that the turbulence correlation time, the drift time associated…
