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)…
