Calculation of the population density in the low pressure mercury-argon discharge: analysis of the steady state and sinusoidal operating modes of the positive column [PDF]

open access: yesJournal de Physique III, 1993
This work deals with the setting up of a collisional-radiative model concerning low pressure mercury-argon discharge operating under different power supplies (dc and ac). This model allows determination of various characteristic quantities of the discharge using the population and electronic energy conservation equations. In view of optimisation of the
