摘要：

We have observed Bose-Einstein condensation of large numbers of Rb-87 atoms in a magnetic time-averaged orbiting potential (TOP) trap. Over 1.5X10(9) atoms are captured in the trap and evaporatively cooled to produce condensates containing up to 2X10(5) atoms. We discuss special considerations relating to the production of large Bose-Einstein condensates in a TOP trap, and present measurements of the condensate fraction for this case.
