Abstract

A new filter spectrometer for the simultaneous measurement of plasma ion temperature and rotation velocity on the experimental advanced superconducting tokamak is proposed. The Doppler broadening and Doppler shift of the plasma spectral line is determined by the signal intensity ratio of the three-filter channels that have different peak wavelengths. A rapid calculated algorithm of the temperature and rotation velocity is presented. This filter spectrometer will allow researchers to measure spectra with a temperature and velocity range of 0.1–5 keV and
