Plasma rotation in a Tokamak has a strong influence over plasma stability and the extent to which turbulent transport is suppressed. Driving plasma rotation in ITER and future fusion power plants with external momentum injection of neutral atoms is challenging considering the extreme temperature and density conditions of the plasma. This has driven a worldwide research effort to predict the intrinsic rotation levels of a plasma discharge i.e. in the absence of external momentum sources and on the transport mechanisms ruling plasma rotation .

The group is actively involved in international collaborations probing

  • Rotation mechanisms in JET ohmic and auxiliary heated plasmas including validation against gyrokinetic codes
  • Role of plasma density, magnetic shear and impurities on intrinsic toroidal rotation in Tokamaks (JET, DIII-D, Tore Supra)
  • Transport of plasma momentum in Tokamak discharges
