Abstract

In the turbulent heating experiment of the high-field tokamak TRIAM-1, the bulk ion heating shown by the neutral energy analyzer measurement is confirmed by the Doppler broadening measurement of visible lines. The increasing rate and decay time of the Doppler ion temperature are almost the same as those derived from the neutral energy analyzer measurement.From both methods of ion temperature measurements, it is shown that the ion temperature has a parabolic profile within 50 jus after the application of the heating pulse.
