Abstract

Experiments on the JET tokamak show that the wave-induced pinch in the presence of toroidally asymmetric waves can provide a tool for controlling the profile of ion-cyclotron-resonant [Formula presented] ions. Direct evidence for the wave-induced pinch has been obtained from the measured [Formula presented]-ray emission profiles. Concurrent differences in the excitation of Alfvén eigenmodes (AEs), sawtooth stabilization, electron temperatures, and fast-ion stored energies are observed. The measured location of the AEs and [Formula presented]-ray emission profiles are consistent with the fast-ion radial gradient providing the drive for AEs. © 2002 The American Physical Society.
