Abstract
Different diagnostic information has been employed in JET to identify the level of interaction between lower hybrid waves and fast ions acce lerated up to few MeV by ion cyclotron waves. It is found that up to 2 5% of the lower hybrid power can be absorbed by fast ions under specif ic plasma conditions. Fourier analysis of neutron emission rates and f ast ion energy signals during lower hybrid modulation experiments show that the level of interaction depends on the relative position of the cyclotron resonance and the lower hybrid absorption layers.
