An advanced time-dependent collisional-radiative model of helium plasma discharges

Abstract: A new spatially averaged time-dependent collisional-radiative model for helium plasmas, coupled to the electron Boltzmann equation (EBE), has been developed. Its main novelties are:(1) full time dependence for both the multi-species kinetics and the EBE. It is shown that this is necessary to correctly simulate discharges where the parameters vary on nanosecondsmicrosecond timescales. (2) All electron processes are accounted for accurately. In particular, for the various ionization and recombination processes, … Show more

“…During plasma formation, He + and He * created by C 3+ impact excitation and ionization of helium atoms transform rapidly into helium dimer ion, in fact He + 2 is well known to be the most abundant ion species in medium/ high density helium plasma 12,23,24 . Helium dimer ions formation follows fundamentally two paths:…”
