Abstract

We realize a novel high flux source of cold atoms and molecules employing hydrodynamic enhancement of an effusive aperture at cryogenic temperatures. Molecular oxygen from the source is coupled to a magnetic guide, delivering a cold, continuous, guided flux of 3e12 oxygen molecules per second, with a molecule temperature of a few kelvin. The dynamics of the source are studied by creating and spectroscopically analyzing high-flux beams of atomic ytterbium.
