We have produced a very cold sample of spin-polarized trapped atoms. The technique used dramatically simplifies the production of laser-cooled atoms. In this experiment, 1.8× 10 7 neutral cesium atoms were optically captured directly from a low-pressure vapor in a small glass cell. We then cooled the< 1-mm 3 cloud of trapped atoms and loaded it into a low-field magnetic trap in the same cell. The magnetically trapped atoms had an effective temperature as low as 1.1±0.2 μK, which is the lowest kinetic temperature ever observed and far colder than any previous sample of trapped atoms.
