In discharges with either high electron density or high gas pressure, it is often believed that an equilibrium Boltzmann distribution among excited particles will be reached due to the presence of strong collisional processes. In this work, using a new collisional–radiative model for low-temperature argon discharges, it is found that the population distribution of atoms in Paschen 2p excited levels significantly deviates from the Boltzmann distribution over a wide operating parameter range found in many discharges reported in the literature. The finding has also been confirmed by experimental measurement for several different types of discharges with pressure ranging from 1 Pa to atmospheric pressure. This result can have a significant impact on both plasma modelling and the interpretation of the optical emission spectra collected from the discharges, in particular in the microdischarges operated at atmospheric pressure. |
