FINAL DESIGN OF THE MAIUS-2/3 PAYLOAD AN ATOM INTERFEROMETER ON A SOUNDING ROCKET

Kurzfassung

In January 2017 a first sounding rocket mission housing experiments on matter-wave interferometry, MAIUS-1 (Materiewellen-Interferometrie unter Schwerelosigkeit Matter-Wave Interferometry under Microgravity), has been launched. Following this campaign, two sounding rocket missions, MAIUS-2 and MAIUS-3, are planned to perform sequential and simultaneous dual-species atom interferometry with Bose-Einstein condensates (BEC) of Potassium-41 and Rubidium-87. The scientific payload of the MAIUS missions will be launched on-board a VSB-30 sounding rocket launched from Esrange in Sweden. The ights of these rockets allows for approximately 360 s of microgravity conditions. It therefore overs a microgravity environment for experiments on timescales not accessible in ground based experiments, such as in the drop tower. During ascent of the rocket, vibrational loads of up to 1.8 g RMS in the frequency range of 20- 2000 Hz and accelerations of up to 13 g can occur. Furthermore, static loads, caused by the re-entry and the landing, can be as high as 50 g. Both missions MAIUS-2 and MAIUS-3 y the same payload, called MAIUS-B. Consequently, the payload needs to be designed to withstand the aforementioned loads
