Electronics for Quantum Optics on a Sounding Rocket — •Thijs Wendrich, Hossein Abedi, Wolfgang Bartosch, Manuel Popp, and Ernst Maria Rasel for the QUANTUS collaboration — Leibniz Universität Hannover, Institut für Quantenoptik

Microgravity experiments with ultra cold degenerate quantum gases offer possibilities to test fundamental laws of physics to unprecedented precision. However, the apparatuses to make these measurements must be very compact and robust to operate in microgravity. Especially the operation of such an experiment on a sounding rocket to obtain several minutes of microgravity poses stringent requirements on the mass, volume and especially the reliability of the experiment. Due to these requirements, almost everything had to be designed ourselves for the MAIUS rocket missions.

In this poster we present the electronic systems of the MAIUS matter-wave microgravity experiments and some of its subcomponents like laser current drivers, BEC-chip current drivers and FPGA-based laser frequency controllers with automatic spectroscopy locking developed for these and other microgravity projects.

The QUANTUS/MAIUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number 604 107 22.
