Abstract

The application of Alcator C-Mod plasmas to measure toroidal rotation velocity using a tangentially viewing x-ray spectrometer array was discussed. It was found that in the EDA H-mode plasmas the rotation propagates in from the plasma edge on a time scale similar to the energy confinment time and evolves to a flat rotation profile, whereas in ELM-free discharges the rotation profiles were centrally peaked. The result shows that the H-mode observations indicated momentum diffusivity of ∼0.1 m ₂/s, which was larger than neoclassical value, and the momentum transport was regarded as anomalous.
