Hα 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 ∼ 10 14 +10 17 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.
