The NASA-DLR Bose-Einstein condensate and Cold Atom Laboratory (BECCAL) is a joint multi-user, multi-purpose facility to exploit the unique microgravity conditions on the International Space Station (ISS) for experiments with condensed Rb and K atoms in regimes inaccessible on ground. In microgravity, no gravitational sag acts on an atomic ensemble and it stays at rest with respect to its environment. This enables an extended time of flight in free fall at the order of seconds to tens of seconds. These two aspects are essential for the various experiments enabled by BECCAL.
The system will be based on an atom chip for efficient evaporation and excellent control of the quantum degenerate atomic clouds. The setup will provide a variety of trapping potentials including static and RF-dressed magnetic as well as red- and blue-detuned optical potentials. BECCAL will serve as a platform to realize experiments in atom optics, physics of quantum degenerate gases, their mixtures, and atom interferometry. Here, we present an insight on some of the proposed experiments and the current status of the project.
The BECCAL project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under the grant numbers 50 WP 1431 and 1700.
