Matter-wave sensors are considered as one of the most promising fields to progress in metrology and fundamental tests. In this poster, we report about the development of a miniaturized and robust experiment using ultra cold atoms in a free fall environment as a test-bed for matter-wave interferometry on long timescales. More than 200 experiments were successfully performed in microgravity and a BEC was observed after free expansions of up to 1s [1]. The implementation of an atom interferometer operating with a Bose-Einstein Condensate was recently demonstrated and several experiments carried out.
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 50 WM 1131.
