Trapping of Neutral ⁸⁷Rb Atoms on an Atomchip

We report an experiment of trapping of neutral ⁸⁷Rb atoms on a self-made atomchip. The H-shaped atomchip is made by magnetron sputtering technology, which is different from the atomchip technology of other teams. We collect 3×10^{6 87}Rb atoms in the mirror magneto-optical trap (MOT) using the external MOT coils, and 1×10^{5 87}Rb atoms are transferred to U-MOT using U-shaped wire in chip and a pair of bias coils.
