Notizen: A successful proof-of-principle experimental determination of ion temperature in a tokamak plasma via cw far-infrared (FIR) collective laser scattering from ion Bernstein waves is reported. The Bernstein waves are excited via mode conversion of an externally launched fast Alfven wave at the second-harmonic cyclotron layer. A fit of the experimentally determined ion Bernstein wave dispersion to the temperature-dependent theoretical dispersion yields the local ion temperature. Partial ion temperature profiles (chord averaged) have been obtained with temperature values consistent with charge exchange measurements. Single-shot measurements should be available in the near future with the use of the multichannel scattering systems and high-power laser sources developed at UCLA.
