This report discusses the Air Forces enhanced flow reactor. The major items purchased were a bakeable, differentially pumped, UHV envelope to interface the mass spectrometer to the flow tube and an excimer pumped dye laser system for laser excited fluorescence LEF detection of radicals in the flow tube. The LEF system, employing a Lambda Physik excimer pumped dye laser EMG 103 MSCFL 2001, has been operational since mid-autumn. It has already been used in preliminary studies of our new methoxy radical source. Completion of the mass spectrometer system was delayed by a variety of problems. However, by late October the required parts were on hand, and the vacuum envelope, sans mass spectrometer, was successfully pumped down. The complete system is currently assembled adn undergoing final testing reactions. Keywords Hydroxylradical, and Chemical reactions.
