Designing high precision electronics for atom interferometers in space applications — •Alexandros Papakonstantinou, Isabell Imwalle, Christian Reichelt, Matthias Koch, Thijs Wendrich, and Ernst M. Rasel — Institut für Quantenoptik, Leibniz Universität Hannover

Atom interferometers are a powerful tool for precision measurements. Their sensitivity scales with the free fall time, which on ground is limited by the size of the vacuum chamber. In microgravity this limitation disappears, enabling higher sensitivities. However, typical microgravity platforms like sounding rockets or the ISS have restrictions on size, weight and power. Also, the apparatus needs to be robust enough to survive the trip into space. In addition it should be fully remote controlled with a high degree of automation. For our microgravity experiments QUANTUS-1/-2 (drop tower), MAIUS-1/-2 (sounding rocket) and BECCAL (ISS), we have developed such components, including laser current drivers, atom-chip current drivers, RF and microwave generators, photodiode and temperature monitoring, power supplies and many more. This poster will show the progress and latest results of our developments.
