Abstract
We have measured the electron drift velocity, longitudinal diffusion coefficient, and ionization coefficient in tetrafluoroethene (C_2F_4). Using these data and the results of ab initio calculations of the elastic, momentum-transfer, and neutral-excitation cross sections, along with measurements of the partial ionization cross sections, we have performed a swarm analysis in order to construct a self-consistent set of electron impact cross sections for C_2F_4. The swarm analysis consists of solutions to Boltzmann’s equation for electrons in C_2F_4 for values of E/N⩽500Td and direct Monte Carlo simulation of electron transport in C_2F_4 for 500Td⩽E/N⩽2000Td. We present an analysis and discussion of the sensitivity of cross sections derived from swarm data to uncertainties in the electron transport measurements. We also discuss the failure of the two-term spherical harmonic solution to Boltzmann’s equation for E/N>500Td, which necessitated the use of Monte Carlo simulations for high values of E/N.
