Doppler broadenings of impurity (0, N and C) lines in hydrogen dischargeswere observed with the JET-2 and DIVA tokamak devices for the purpose ofdetermining the spatial distribution of the ion temperature. A l-meter Czerny-Turner type vacuum monochromator was used in higher orders for sufficientresolution. Impurity emissions are localized in shell-like regions in the minorcross-section. The radial distribution of the ton temperature was determinedfrom the Doppler broadening of various impurity lines and from the Iocalizationof line intensities. The Doppler temperatures of the 0" ion were found to be256 eV for a 100 kA, 14 kG discharge with JFT-2 and 220 eV for a 28 kA, 20 kGdischarge with DIVA.
