Research Abstract

Properties of the toroidal momentum diffusivity and the convection velocity in JT-60U H-mode plasmas have been obtained by various plasma parameter scans. The role of electron cyclotron resonance heating (ECRH) on the toroidal rotation velocity profile has been investigated in the JT-60U tokamak device by separating the effects of the change in momentum transport, the intrinsic rotation by pressure gradient and the intrinsic rotation by ECRH.
