Description
We present the design, implementation and characterization of a new dual-species cold atomic mixture of $^{39}$K and $^{23}$Na with a large number of atoms. The dual species Magneto Optical Trap (MOT) has more than 10$^{10}$ $^{39}$K atoms and 5$\times$10$^9$ $^{23}$Na atoms, which are simultaneously loaded using two independent 2D$^+$MOT with high cold atomic beam flux. The dual cold atomic clouds were further cooled to tens of $\mu$K via sub-Doppler cooling and Gray molasses technique. The $^{23}$Na and $^{39}$K atoms are thereafter transferred into a quadrupole magnetic trap and transported towards the “Science cell” for further experiments. This versatile experimental system provides a favourable starting point for the realization of the quantum degenerate Bose-Bose mixture for quantum simulation with ultracold quantum gases in optical potentials.
