The dispersion relation of the waves excited in a turbulently heated plasma has been studied by microwave scattering method, and it is identified to be that of the ion acoustic mode. The phase velocity of the wave has been observed to increase with time, indicating the increase of the electron temperature T_e with time. A space-averaged density fluctuation, as evaluated from a microwave interferometric measurement, has shown to build up at about 0.8μsec after the initiation of the heating discharge. The time when the density fluctuations saturate is found to correspond roughly to the time of the formation of a high energy tail in the ion distribution function observed in a previous experiment.
