Towards dual species interferometry in space: MAIUS-B laser system — •Pawel Arciszewski1, Klaus Döringshoff1, Achim Peters1, and The MAIUS Team1,2,3,4,5 — 1Institut für Physik, Humboldt-Universität zu Berlin — 2Ferdinand-Braun-Institut gGmbH, Leibniz-Institut für Höchstfrequenztechnik, Berlin — 3ZARM, Zentrum für Angewandte Raumfahrttechnologie und Mikrogravitation, Bremen — 4Institut für Physik, JGU Mainz — 5IQO, Leibniz Universität Hannover
The first production of a space-borne BEC carried out during the MAIUS-1 sounding rocket mission in January 2017 paved the way for more advanced experiments with an ultra-cold matter in space. The goal of upcoming MAIUS-2 and MAIUS-3 missions is to perform dual-species interferometry onboard a sounding rocket to investigate the weak equivalence principle.
To make that possible a new laser system was developed. The designed equipment can provide the light needed for simultaneous laser cooling of rubidium and potassium and further stages used in atom interferometry experiments. Moreover, the system has to be robust and reliable to meet the demands of a sounding rocket mission.
We report on the current status of the system, its assembly process, and used technologies as well, as tests carried out to assure the equipment can face the present needs of the mission.
