Local dependence of ion temperature gradient on magnetic configuration, rotational shear and turbulent heat flux in MAST

Y. -c. Ghim, A. R. Field, A. A. Schekochihin +3

Experimental data from the Mega Amp Spherical Tokamak (MAST) is used to show that the inverse gradient scale length of the ion temperature R/LTi (normalized to the major radius R)…

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…

Experimental verification of Boltzmann equilibrium for negative ions in weakly collisional electronegative plasmas

Y. -C. Ghim, N. Hershkowitz

Weakly collisional Ar-O2 electronegative plasmas are investigated in a dc multidipole chamber. An electronegative core and an electropositive halo are observed. The density ratio o…

Measurement and physical interpretation of the mean motion of turbulent density patterns detected by the BES system on MAST

Y. -c. Ghim, A. R. Field, D. Dunai +4

The mean motion of turbulent patterns detected by a two-dimensional (2D) beam emission spectroscopy (BES) diagnostic on the Mega Amp Spherical Tokamak (MAST) is determined using a…
