我们描述了实验装置生产大玻色-爱因斯坦凝聚的Na 23和Rb 87。在这两种情况下，高通量热原子束被塞曼减速器减速，然后被捕获并在磁光阱中冷却。然后，原子被转移到一个三叶草式的Ioffe-Pritchard磁阱中，并通过射频诱导的强制蒸发冷却到量子简并。典型的凝聚体含有20×106个原子。我们讨论的相似性和差异的技术用于生产大的Rb 87和Na 23冷凝物的上下文中几乎相同的设置。
We describe experimental setups for producing large Bose-Einstein condensates of Na23 and Rb87. In both, a high-flux thermal atomic beam is decelerated by a Zeeman slower and is then captured and cooled in a magneto-optical trap. The atoms are then transferred into a cloverleaf-style Ioffe-Pritchard magnetic trap and cooled to quantum degeneracy with radio-frequency-induced forced evaporation. Typical condensates contain 20×106 atoms. We discuss the similarities and differences between the techniques used for producing large Rb87 and Na23 condensates in the context of nearly identical setups.
