Computer simulated Balmer-alpha, -beta and -gamma Stark line profiles for non-equilibrium plasmas diagnostics

Balmer-alpha, -beta and -gamma lines have been calculated using computer simulations including ion dynamics effects for equilibrium and non-equilibrium conditions. The results obtained allow us to supply diagnostic maps based on the widths of those lines, as well as the Stark broadened full line profiles and the dipolar correlation functions obtained in the simulations. These profiles and correlation functions are a better diagnostic tool than the widths of the profiles in case of non-equilibrium plasmas. Calculations cover the range of electron densities between 10(20) and 10(25) m(-3) and of electron temperatures between 1000 and 175 000 K. The emitter and the perturber ions kinetic temperature may vary between the value of the electrons temperature and one tenth of it. (C) 2003 Elsevier B.V. All rights reserved.
