We describe an experimental system that integrates the techniques for producing ultracold atomic gases with the techniques for cooling solid bodies to cryogenic temperatures. Ultracold clouds of 87Rb are prepared in a trap setup based on room-temperature coils and subsequently transported to a superconducting microstructure by means of optical tweezers. The superconducting microstructure generates a magnetic microtrap and is cooled by a helium-flow cryostat that can achieve temperatures down to 2 K. Both the room-temperature trap setup and the superconducting microtrap are installed in the same ultra-high-vacuum chamber. The presented system is well suited to create hybrid quantum systems by combining ultracold atomic gases and superconducting devices.
