Calculation of the H α line profile in a high-temperature plasma

Abstract

A new method for calculating broadening of the H α line profile in a high-temperature plasma is proposed. Using the new program H-ALPHA, one can calculate the H α line profile with an error smaller than 3% in a wide range of electron temperatures and densities (T e=1–500 eV, n e=1014−1017 cm−3). On the basis of these calculations, a method for the measurement of plasma temperature and density from the experimental H α line profile is developed. The experimental tests of the method showed a good agreement with the diamagnetic measurements.
