Abstract : The dissociative attachment of low energy electrons to fluorine is a potential source of fluorine atoms in electrically initiated hydrogen-fluorine chemical laser systems. The ARL flowing afterglow system was developed to measure the rate of this reaction. Electrons are produced in a microwave discharge and react with fluorine, and the resulting negative ions are sampled through an orifice at the end of a reaction channel. Two other reactions were also studied in the process of developing the experimental technique: the charge transfer reaction between diatomic negative oxygen ion and sulfur hexafluoride and electron attachment to sulfur hexafluoride.
