Transfer rates of toroidal angular momentum during neutral beam injection
At the onset of neutral beam injection in Joint European Torus (JET) the torodial angular momentum is observed to rise instantaneously in the outer regions of the plasma. The toroidal angular momentum in the plasma centre, where the fast ions are injected into passing orbits, and the thermal energy are found to rise on the slowing down time scale of the fast ions. This behaviour can be explained by a model that incorporates three mechanisms for momentum transfer of fast ions to the bulk. The model for the torque is applied to the study of toroidal angular momentum confinement in transient hot-ion H-mode plasmas in JET.
