Observation of fast wave and mode-converted ion Bernstein wave by magnetic probes and 2-mm microwave scattering

Abstract

The observation of mode conversion during ICRF heating in a deuterium-hydrogen plasma is described. The mode-converted ion Bernstein wave is detected near the ion-ion hybrid resonance layer by 2-mm microwave scattering. In addition, a fast magnetosonic wave is also observed by magnetic probes inserted into the plasma. The plasma dispersion of both waves as determined experimentally agrees well with the results of calculations for a hot plasma.
