Abstract
A methyl radical source has been developed for use in high vacuum. Methyl radicals are produced through azomethane pyrolysis in a tubular reactor located inside an ultrahigh vacuum chamber. Other gas products include nitrogen from azomethane pyrolysis, and methane, ethane plus hydrogen from the reactions of methyl radicals on the walls of the reactor. Methyl yields as high as 42% have been observed.Keywords
