Shaped nozzles for cryogenic buffer gas beam sources
arXiv:1810.02910 · doi:10.1103/PhysRevA.99.013603
Abstract
Cryogenic buffer gas beams are important sources of cold molecules. In this work we explore the use of a converging-diverging nozzle with a buffer-gas beam. We find that, under appropriate circumstances, the use of a nozzle can produce a beam with improved collimation, lower transverse temperatures, and higher fluxes per solid angle.
