Abstract

The spatially and temporally resolved toroidal rotation measurements made in DIII-D discharges with no externally applied torque were discussed. It was found that the velocity measurements were made using the charge exchange recombination (CER) technique viewing emission from the intrinsic carbon impurity in deuterium discharge. The cases of L mode, H mode with Ohmic heating and H model with electron cyclotron heating (ECH) were analyzed. Analysis shows that the counter-rotation measured for carbon in the core of the ECH mode was also predicted for the bulk deuterium species.
