Realization of a magnetically guided atomic beam in the collisional regime

Other Condensed Matter 2009-11-10 v1

Abstract

We describe the realization of a magnetically guided beam of cold rubidium atoms, with a flux of 7×1097\times 10^9 atoms/s, a temperature of 400 μ\muK and a mean velocity of 1 m/s. The rate of elastic collisions within the beam is sufficient to ensure thermalization. We show that the evaporation induced by a radio-frequency wave leads to appreciable cooling and increase in phase space density. We discuss the perspectives to reach the quantum degenerate regime using evaporative cooling.
