Abstract

The new spectroscopic method for measurement of hot plasma parameters is developed. The method based on Ha profile monitoring. The profile was accurately calculated for a wide range of plasma parameters (n$_e \sim $ 10$^{14} \div $ 10$^{17}$ cm$^{-3}$, T$_e \sim 1\div$500 eV) Use of the method in the experiment gives the electron density and ion temperature dependence from the time. Measurements was in a good agreement with diamagnetic loop dates. Key words: H$_\alpha$ spectroscopy, line profile, density and high temperature measurement.
