avt cf4 monitor and record for gas measurement

Nov 10, 1989 · Measurements of the electron drift velocity and positive-ion mobility for gases containing CF 4 have been performed. The results are presented for four types of gas mixtures containing CF 4 and hydrocarbons: CF 4 +CH 4, CF 4 +C 2 H 6, CF 4 +C 3 H 8 and CF 4 +iso-C 4 H 10. To make a comparison, also positive-ion mobilities for Ar+C 2 H 6 and Ar+C 3 H 8 gas mixtures have been measured.
