Here is a description of the apparatus (parts of Ananth Chikkatur's Thesis) (pdf, 1.7 MB). In 2007, the experiment was upgraded to have the capability of producing ultracold clouds of both fermionic lithium-6 and bosonic sodium-23. This allows us to study various quantum phase phenomena with fermions or Bose-Fermi mixtures. We are preparing for optical tweezer transport of fermionic lithium atoms into our science chamber, which will allow maximum optical access for various optical lattice experiments.

Main Experiment Table

Our ultracold atoms of sodium and lithium are produced here. They begin as hot gases at >300 degrees Celsius in a dual-species oven. Both types of atoms travel down a Zeeman slower and are captured by overlapping magneto-optical traps (MOT)

consisting of yellow and red lasers tuned to sodium and lithium transition frequencies respectively.

...

After being cooled to micro-Kelvin temperatures in the MOT, our atoms are transferred into a magnetic trap and evaporatively cooled to nano-Kelvin temperatures.
