Toroidal Rotation in Ohmic and RF Heated JET Plasmas

Understanding the origin of rotation in ICRF heated plasmas is important for predictions for burning plasmas sustained by alpha particles, as both are characterised by a large population of fast ions and no external momentum input. Recent experiments performed at JET investigated rotation in Ohmic and purely ICRF heated plasmas. The aim of recent experiments with ICRF heating was to establish under which conditions co and counter rotation arise and to build up a database on how intrinsic rotation in JET scales with the plasma current and ICRF heating details. Determination of the rotation induced with ICRF heating requires taking into account the rotation in Ohmic heated plasmas. Previous studies of rotation with Ohmic heating were in limiter plasmas, here studies in the divertor configuration are reported.
