A ground-based, transportable testbed for space-borne dual species atom interferometers — •Alexander Herbst, Dennis Becker, Kai Frye, Maike D. Lachmann, Baptist Piest, and Ernst M. Rasel — Leibniz Universität Hannover

Space-borne atom interferometers are promising candidates for a new generation of tests of the universality of free fall. After the sounding rocket mission MAIUS-1 which demonstrated the first Bose-Einstein condensate (BEC) in space using Rb-87, we aim to add K-41 and perform two-species atom interferometry on the upcoming missions MAIUS-2 and -3. Due to the complexity of the experiment and the strict requirements for space missions, extensive testing of the experimental procedures is required. We present a ground-based and transportable testbed for the creation of a dual species BEC of Rb-87 and K-41 in the MAIUS-B physics package. The overall layout and the control electronics closely resembles the flight system that will be used for MAIUS-2. The modular, fiber-based design of the laser system allows for independent operation at 780 nm and 767 nm, transportation to different testing facilities and easy extension regarding the tests of future experiments like the upcoming ISS multi-user facility BECCAL.
