Abstract

The rotation and momentum transport has been studied at JET. The analysis showed that the rotation and temperature profiles match each other for the ITB discharges but not for the H-mode plasmas. This could be explained by the difference in NBI energy and momentum deposition in high density H-mode plasmas. The central Mach numbers differ between the ELMy H-modes and the ITB discharges. Higher values were found for the ITB discharges. The effective diffusion coefficients for ion heat and momentum deviate in the gradient region of JET plasmas, giving a Prandtl number of Pr=0.2 to 0.3.
