Electron Mobility Studies in Mixtures of CHF3 and Argon
Abstract
Electron drift velocity measurements were made in CHF3 and Argon mixtures, using a pulsed Townsend type drift tube. Drift velocities were measured as a function of E/N in mixtures ranging from 0.1 to 2 percent CHF3 in Argon, and E/N range of 0.04 to 10 Td. A two term Boltzman transport code was used to unfolded a preliminary set of low energy electron scattering cross sections for CHF_3. The dominate cross sections considered in this low energy (0-10eV) range are the total momentum transfer and vibrational excitation. Comparison of experimental and calculated drift velocities will be presented.
