Abstract A self-consistent steady-state spatially averaged collisional-radiativemodel in which the rate coefficients involving electrons are calculatedfrom the solution to the electron Boltzmann equation has been developedfor describing an atmospheric pressure plasma in helium–nitrogen(He–N2) mixtures. The influence of small nitrogenconcentrations (typically less than 1%) on the discharge characteristicsis studied and compared with available experimental data. It is foundthat nitrogen is highly dissociated and that the density of metastablehelium atoms is considerably reduced by the presence of nitrogen, evenat such low concentrations.
