Abstract

The q-profile has been determined inside the q = 1 surface of ion cyclotron resonance frequency (ICRF) heated plasmas from the observed toroidicity induced Alfvén eigenmodes (TAE) that appeared before giant sawtooth crashes. The q-profile deduced from the TAE spectrum is in good agreement with the one obtained from motional Stark effect measurements.
