By using a spectrometer fitted with a multichannel detector, we have observed a chord dependence of emission-line profiles of OV and CV impurities in a WT-III tokamak plasma in a Joule-heating mode. After Abel-inversion of the observed intensity for each channel of the detector, we obtained a Doppler-line profile as a function of radius. Ion temperatures derived from the two lines agree with each other and are consistent with the energy distribution of neutral particles emanating from the plasma.
