Purpose： The ERD system is an effective method to research the radiation phenomenon of C, O, Li, N, He and Ar in visible range. The ERD has been used for the measurement of ion temperature and rotation velocity at the edge plasma. Methods： The measurement was done by using an optical fiber spectrometer and two systems of lenses. Results： The ion radiant flux coupled by each fiber can be expressed as an analytical form, and the sightline of each fiber was determinated, and the spectrometer was calibrated by using a halogen lamp. Conclusions： The initial experimental results were obtained by ana |
