Transference of Cold 85Rb Atoms from a Mirror MOT to U-MOT on an External Atom Chip

다국어 초록 (Multilingual Abstract)

We have designed an atom chip for manipulating cold atoms with magnetic fields generated by electric currents. Electric wires with a U shape for a quadrupole trap and a Z shape for the Ioffe-Pritchard trap were printed on the 26 mm × 26 mm chip. This chip was bonded on a 16 × 16× 70 mm3 glass cell. The glass cell was for a mirror MOT. 85Rb atoms are magneto optically trapped near the chip’s surface (mirror-MOT); then, the trapped atoms are transferred from the mirror-MOT to the U-MOT by gradually decreasing the magnetic field for the mirror-MOT while increasing the current for the U-MOT. A transfer efficiency of 27.1% was measured by comparing the fluorescence from the atoms of U-MOT and the mirror-MOT.
