FIG. 2. Simplified experimental sequence. The Yb MOT is loaded, then cooled and compressed to facilitate subsequent loading into an ODT. The Yb is then evaporated in the ODT by ramping the trap depth until a temperature of T = 550 nK is reached. The displaced Cs MOT is loaded before it is compressed, cooled, and transferred into a near-detuned optical lattice for DRSC. The DRSC stage loads Cs into the ODT, where it is held with Yb for a variable time t before the trap is switched off and the atoms are destructively imaged after a variable time of flight using dual-species absorption imaging.
