H_α Spectroscopy for Hot Plasma Parameters Measurement

The new spectroscopic method for measurement of hot plasma parameters is developed. The method based on H_α profile monitoring. The profile was accurately calculated for a wide range of plasma parameters (n_e∼10¹⁴÷10¹⁷ cm⁻³, T_e∼1÷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.
