We describe the setup to create a large Bose-Einstein condensate containing more than 120x10^6 atoms. In the experiment a thermal beam is slowed by a Zeeman slower and captured in a dark-spot magneto-optical trap (MOT). A typical dark-spot…
We demonstrate a dual magneto-optical trap of $^{109}$Ag and $^{39}$K. For silver, a decreasing-field Zeeman slower loads a MOT of $1.5{\times}10^8$ atoms at a temperature of 0.74(5) mK, with laser cooling occurring primarily on the $D_2$…

We have examined loading of 85Rb atoms into a shallow Far-Off-Resonance Trap (FORT) from an optical molasses and compared it to loading from a Magneto-Optical Trap (MOT). We found that substantially more atoms could be loaded into the FORT…
In a recent paper, we have used the dark-spot Zeeman tuned slowing technique [Phys. Rev. A 62, 013404-1, (2000)] to measure the capture velocity as a function of laser intensity for a sodium magneto optical trap. Due to technical limitation…
