“…In pure gases, the Townsend ionization coefficient α has been studied in several works and is well known in pure Ar [32][33][34][35] and pure N 2 [36][37][38][39]. To date various mixtures of Ar with other gases have been investigated: Ar with Ne [40,41], methane [42], ethane [43], and dimethyl-ether [44]. However, α in mixtures of Ar with N 2 has experimentally been determined only for N 2 fractions of 0.8 and 0.5 by Jovanovic et al [45] and a few works have computed α/N for 1:1 mixtures [46,47].…”

Mixtures of Ar with N 2 are relevant for many areas of plasma applications. In particular, modeling of atmospheric pressure plasma jets for biomedical applications requires precise knowledge of fundamental gas parameters such as the Townsend ionization coefficient α. This study determines α in mixtures of Ar with N 2 in a dark non-self-sustaining Townsend discharge. The discharge current versus electrode spacing was measured in the absolute pressure range of 10-800 Torr and reduced electric field strength E/N range of 40-1000 Td. The density normalized ionization coefficient α/N increases with E/N and decreased with N 2 content in the gas mixture. A good coincidence between measurements and calculations with Bolsig+ was observed. In case when N 2 concentration was between 10% and 50% in the mixture, experimental results were 20%-30% lower than predicted by Bolsig+ calculations. The results of this work were compared with α/N determined in mixtures of He with up to 10% of N 2
