QUANTUS-2 is a mobile, robust, high flux 87Rb atom interferometry device that can operate in the microgravity environment provided by the drop tower and Gravitower located in Bremen and act as a pathfinder for future space missions. QUANTUS-2 exploits a magnetic lens enhanced by the quadrupole field of the atom chip which enables longer coherence times under microgravity to perform atom interferometery over one second with double Bragg diffraction.
Here, we present the latest results on atom interferometry on extended time scales in the drop tower and initial experiments in the Gravitower.
This project is supported by the German Space Agency
DLR with funds provided by the Federal Ministry for Economic Affairs and Climate Action under grant number DLR 50WM1952-1957.
