| Abstract: | Processing method of chord_integral spectral signal has been discussed. Radial profile of spectral line emission coefficient has been derived from the distribution of intensity by Abel inversion. The local ion temperature and rotation velocity has been obtained from the line shape by a chosen_point fitting technique. |
