Electron swarm parameter in SF/sub 6/+Ar mixture gas

The electron swarm parameters in the 0.5% and 0.2% SF/sub 6/-Ar mixtures are calculated by Monte Carlo simulation over the E/N(Td) range from 30 to 300 (Td) and by a backward-prolongation of the Boltzmann equation considering the latest cross section. The result two-term approximation of the Boltzmann equation analysis shows that the values of electron parameters such as the ionization, attachment, effective ionization coefficients and the electron drift velocity. The measurements are carried out by the double shutter drift tube. Electron swarm parameters in pure Ar gas and SF/sub 6/-Ar mixtures are analyzed and compared by the electron Arrival Time Spectra (ATS) of Time Of Flight (TOF) method.
