Abstract

Electron collision cross sections for CF₃I are estimated using the electron swarm method. Electron drift velocity, effective ionisation coefficient, and longitudinal diffusion coefficient in CF₃I are calculated using Monte Carlo method, and the calculated electron transport coefficients are compared with those measured. Calculated electron drift velocity agrees with measured data within the difference of 6% below 1600 Td, and calculated effective ionisation coefficient agrees with measured data within the difference of 10% above 460 Td. Further, those swarm parameters in CF₃I–N₂ mixtures are calculated, and calculated values of electron drift velocity and effective ionisation coefficient agree well with measured data in CF₃I–N₂ mixtures. This confirms the validity of the estimated set.
