Calculation of the Hα line profile in a high-temperature plasma

A new method for calculating broadening of the H-alpha line profile in a high-temperature plasma is proposed. Using the new program H-ALPHA, one can calculate the H-alpha line profile with an error smaller than 3% in a wide range of electron temperatures and densities (T-e = 1-500 eV, n(e) = 10(14)-10(17) cm(-3)). On the basis of these calculations, a method for the measurement of plasma temperature and density from the experimental H-alpha line profile is developed. The experimental tests of the method showed a good agreement with the diamagnetic measurements. (C) 2001 MAIK Nauka/Interperiodica.
