Towards BEC-borne two-species atom interferometry in space — •Maike D. Lachmann¹, Baptist Piest¹, Dennis Becker¹, Wolfgang Ertmer¹, Ernst M.

Tests of the universality of free fall using two-species atom interferometers in space are currently of large interest. By increasing the free evolution time in the interferometer due to the microgravity environment the sensitivity can be enhanced significantly. After the successful launch of the MAIUS-1 mission and the first demonstration of Bose-Einstein condensates in space we aim for two-species atom interferometers on the sounding rocket missions MAIUS-2 and -3. The new system contains, in addition to Rb-87, K-41 as second species and will utilize Raman double-diffraction as beam splitters. The poster will show the mission goals, the setup and the current progress on ground.

QUANTUS & MAIUS are supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant numbers DLR 50WM 1131-1137.
