MEASUREMENT OF H D RATIO AND ION TEMPERATURE ON A HT-6M TOKAMAK/

By combining optical fibers with piezoelectric scanning Fabry-Perot in terferometer, the profiles of H-alpha and D-alpha have been determined simultaneously in a single Tokamak discharge. Consequently, the ratio of hydrogen to deuterium and ion temperature are obtained. Not only i s the uncertainty of shot-to-shot avoided, the results of the experime nt indicate that this instrumentation has the advantage of rapid wavel ength scanning, large dispersion, high resolution, and good adaptabili ty of working in adverse circumstances such as at a Tokamak site.
