We have developed a method that enables loading a magneto-optical trap (MOT) in an ultrahigh vacuum environment. Nearly 1.0 × 108 atoms of 87Rb are trapped in the MOT at ∼2.0×10−10 Torr base pressure in the chamber. After the MOT loading, we have successfully demonstrated the working of a quadrupole magnetic trap in this chamber with a lifetime of ∼15 s.
