Atom chips enable compact and robust apparatuses for matter-wave interferometry and condensed matter physics. Usually these setups are limited in the total number and the flux of atoms. In this talk we present the QUANTUS-II apparatus, which uses a combination of a chip-based atom trap with a pre-cooling stage. This apparatus allows to collect >3·109 atoms within 3 seconds in a mesoscopic chip MOT. This is an excellent starting point towards the realisation of a high precision matter-wave interferometer.
The QUANTUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM1131.
