Calculation Mobility & Transverse, Longitudinal Diffusion Coefficients In SF6 Gas Under The TOF Condition

الملخص

      The electron swarm parameters in electronegative gases for the Time – Of –Flight experiments condition  are calculated using a Boltzmann equation  for the a range of E/N values from 140 to 1000 Td(Townsend ) , using a set of electron collision cross- sections for the SF₆ .The calculated parameters : mobility , diffusion , negative ion mobility , longitudinal and transverse diffusion coefficients. The swarm parameters for important experimental condition are deduced and the validity of the two-term a Boltzmann method checked.
