Atom interferometry in the transportable Quantum Gravimeter QG-1 — •Nina Heine1, Pablo Nuñez von Voigt1, Ludger Timmen3, Waldemar Herr2, Christian Schubert2, Jürgen Müller3, and Ernst M.

The transportable Quantum Gravimeter QG-1 is based on the principle of atom interferometry with collimated Bose-Einstein condensates to determine the local gravitational acceleration aiming for an unprecedented level of accuracy <3 nm/s2. This talk elaborates on the design and implementation of the interferometry setup into the atom chip based experimental system. An introduction to the measurement concept and studies of the interferometer performance will be presented and put into perspective with perfomance estimates for given experimental parameters.
