A simple counter-flow cooling system for a supersonic free-jet beam source assembly
1Centre for Organic Electronics, University of Newcastle, Callaghan, NSW 2308, Australia.
Abstract:
A simple design for an inexpensive, cooled, free-jet beam source is described. The source assembly features an integrated cooling system as supplied by a counter-flow of chilled nitrogen, and is composed primarily of off-the-shelf tube fittings. The design facilitates rapid implementation and eases subsequent alignment with respect to any downstream beamline aperture. The source assembly outlined cools the full length of the stagnation volume, offering temperature control down to 100 K and long-term temperature stability better than ±1 K.
