本文介绍了一种用于产生超冷（87）Rb和（39）K原子气体的双室原子芯片装置。该装置产生准纯玻色-爱因斯坦凝聚的10（4）（87）Rb原子在原子芯片陷阱，具有凹坑和良好的光学访问。我们还证明了超冷（39）K的生产和随后的加载到芯片陷阱。我们描述了双室真空系统，冷却激光器，磁阱，多线圈磁输运系统，原子芯片，和两个光学偶极阱的细节。部分由于使用光诱导原子解吸，激光冷却室具有足够好的真空，也支持基于光学偶极陷阱的实验。该装置非常适合于研究原子表面力，量子泵浦和传输实验，原子干涉，新型芯片为基础的陷阱，和一维多体系统的研究。
We present a dual chamber atom chip apparatus for generating ultracold (87)Rb and (39)K atomic gases. The apparatus produces quasi-pure Bose-Einstein condensates of 10(4) (87)Rb atoms in an atom chip trap that features a dimple and good optical access. We have also demonstrated production of ultracold (39)K and subsequent loading into the chip trap. We describe the details of the dual chamber vacuum system, the cooling lasers, the magnetic trap, the multicoil magnetic transport system, the atom chip, and two optical dipole traps. Due in part to the use of light-induced atom desorption, the laser cooling chamber features a sufficiently good vacuum to also support optical dipole trap-based experiments. The apparatus is well suited for studies of atom-surface forces, quantum pumping and transport experiments, atom interferometry, novel chip-based traps, and studies of one-dimensional many-body systems.
