Electron attachment properties of c-C ₄ F ₈ O in different environments

The electron attachment properties of octafluorotetrahydrofuran (c-C 4 F 8 O) are investigated using two complementary experimental setups. The attachment and ionization cross sections of c-C 4 F 8 O are measured using an electron beam experiment. The effective ionization rate coefficient, electron drift velocity and electron diffusion coefficient in c-C 4 F 8 O diluted to concentrations lower than 0.6% in the buffer gases N 2 , CO 2 and Ar, are measured using a pulsed Townsend experiment. A kinetic model is proposed, which combines the results of the two experiments.
