Abstract
We have produced and characterized an intense, slow, and highly collimated atomic beam extracted from a standard vapor cell magneto-optical trap (MOT). The technique used is dramatically simpler than previous methods for producing very cold atomic beams. We have created a 0.6 mm diameter rubidium atomic beam with a continuous flux of and a pulsed flux 10 times greater. Its longitudinal velocity distribution is centered at 14 m/s with a FWHM of 2.7 m/s. Through an efficient recycling process, 70% of the atoms trapped in the MOT are loaded into the atomic beam.
