Resumo(s)
The model of the near-cathode plasma, developed previously for the case of a
single-species plasma-producing gas, is generalized for the case of multiple
plasma-producing species. Results are presented of calculation of a diffuse
mode of current transfer to tungsten cathodes in a mercury plasma with an
addition of sodium. It is found that the presence of 1% of sodium results in a
considerable expansion of the range of stability of the diffuse mode.
