Monatomic-Oxygen Reactors For Materials Testing And Surface Chemistry

Two kinds of gas-flow reaction chambers expose specimens of materials to spatially even fluxes of monatomic oxygen. Monatomic oxygen diffuses along side-arm tubes attached to flowing-after-glow apparatus. If rate of diffusion high enough, specimens at ends of these tubes receive uniform doses. Monatomic oxygen generated by photolysis in pulsed laser beam diffuses sideways out of laser beam and onto nearby surfaces of specimens.
