Impurity toroidal rotation has been observed in the center of Alcator C-Mod ohmic plasmas from the Doppler shifts of argon and molybdenum x-ray lines. The rotation is highest (~ 6 x 106 cm/s) in the early portion of the discharges, when the loop voltage is highest and the electron density is lowest, and then typically settles to values < 2 x 106 cm/s during(More)
