title = "Toroidal rotation in Ohmic and RF heated JET plasmas",
abstract = "The central region of Ohmic plasmas in the JET divertor configuration are counter rotating with toroidal frequencies up to -8 krad/s. ICRF heated plasmas have been found to either co or counter- rotate with central angular frequencies ranging from -6 krad/s to +10 krad/s. Once the Ohmic rotation is subtracted, one finds in most cases co-current acceleration when ICRF power is applied. In addition, the ICRF induced rotation appears to originate in the plasma core and it was found to be sensitive to the plasma current. The differences in frequency profile shape cannot be attributed to differences in sawtooth instability. The outer part of the plasma is observed to rotate in the co-current direction independently of heating scenario.",
