We have developed an apparatus for creating Bose–Einstein condensates of sodium atoms. Radio-frequency-induced forced evaporative cooling was studied experimentally and optimized to stably create sodium condensates containing a large number of atoms. The transition temperature, the spatial distribution of the condensate, and the aspect ratio of the Bose–Einstein condensate were analyzed quantitatively and compared with theoretical predictions. Several methods of ramping down the rf for evaporative cooling were tested.
