We have produced and characterized an intensc, slow, and highly collimatcd atomic bcani extracted from a standard vapor cell magneto-optical trap (MOT). Thc tcchniquc used is dramatically simpler than previous methods for producing very cold atomic beams. We have created a 0.6 nini diameter rubidium atomic beam with a continuous flux of 5 X 109/s 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 atonis trapped in the MOT are loaded into the atomic beam.
