Discharge Parameters in Xe/He and Xe/Ne Mixtures and their Differences:

Boltzmann Equation Analysis

Abstract

The electron swarm parameters in Xe/He and Xe/Ne gas mixtures were analyzed using a Boltzmann equation in which generation of secondary electrons through Penning and cumulative ionizations, and ionization collision between two metastable Xe atoms as well as direct electron impact ionization were taken into consideration. The ionization coefficient and excitation frequency to the resonance level of Xe in Xe/Ne mixtures at a low E/N region were considerably larger than those in Xe/He. The other swarm parameters in both gas mixtures were compared and discussed.
