Flash pyrolysis nozzle for generation of radicals in a supersonic jet expansion

Abstract
A method for the high‐temperature generation of reactive species in supersonic molecular beams has been developed. Pyrolysis temperatures (25–1800 °C) can be maintained for longer than 100 h for extended experiments. Short contact time (≊10 μs) of the seeded (14 cm−3 at the sonic orifice with radical fluxes of ≊1016 s−1.
