Abstract
Results on fast ion diagnosis by collective Thomson scattering at JET are p resented. 400 kW, 2 mm radiation was scattered in plasmas with energetic pr oton minority populations heated by 4-8 MW ion cyclotron resonance heating. Then is clear evidence of scattering from plasma fluctuations driven by th e fast ion population. In a few cases ion velocity distributions with energ ies in the MeV range could be inferred.
