Abstract :
Magneto-optically trapped (in a mirror-MOT) 87Rb atoms have been observed in microgravity during the 4.5 s. flight. Furthermore, the experiment was able to capture 3ldr106 atoms at the temperature of 40 muK in an Ioffe-Pritchard magnetic chip trap. The corresponding phase-space density is of the order of 10-7. Evaporative cooling - the final stage on the way towards BEC - is currently being implemented.
