Design and characterization of late-mixing flash pyrolytic reactor molecular-beam source Academic Article uri icon

abstract

  • We report on the design and characterization of an intense pulsed beam source for the generation of expansion-cooled radical species. The source combines both dual pulsed valve late mixing for coexpansion of reactive gases with a pyrolytic end nozzle as a flash kinetic reactor. As a demonstration of the source we present evidence of BrO and ClO radical production and subsequent photodissociation studies of these species using velocity map ion imaging. The radicals are characterized by a rotational temperature of 150±40 K although substantially lower temperatures should be possible. © 2005 American Institute of Physics.
