Abstract
The electron transport parameters for both SF6 and O2 have been experimentally determined using the voltage transient method. The electron convective drift velocity (centre-of-mass velocity) We, the longitudinal diffusion coefficient NDL, and the effective ionization coefficient α'/N were determined for electron swarm energies in SF6 and O2. For SF6, the electron transport parameters were determined within the range 360 Td<E/N<720 Td and at a gas pressure range of p≅2 Torr. For O2, the electron transport parameters were determined within the range 20 Td<E/N<270 Td and at a gas pressure range of 2<p<50 Torr. Here, E is the applied electric field and N is the gas number density.
