Characteristics of Electron Drift in an Ar–Hg Mixture

Resumo

The characteristics of electron drift in a mixture of argon with mercury vapor at reduced electric fields of E/N = 1–100 Td are calculated and analyzed with allowance for inelastic collisions. It is shown that even a minor additive of mercury to argon at a level of a fraction of percent substantially affects the discharge parameters, in particular, the characteristics of inelastic processes. The influence of the concentration of mercury vapor in argon on the kinetic characteristics, such as the diffusion and mobility coefficients and ionization frequency, is investigated.
