A mobile atom interferometer for high precision measurements of local gravity — •Malte Schmidt, Alexander Senger, Tais Gorkhover, Ulrich Eismann, Evgeny Kovalchuk, and Achim Peters — Humboldt Universität zu Berlin, Institut für Physik, Hausvogteiplatz 5-7, 10117 Berlin, Germany

In recent years, matter wave interferometry has developed into a powerful tool for the ultra precise measurement of accelerations and rotations. It is used in various laboratories for experiments in the fields of fundamental physics and metrology.

We present a new design for a gravimeter based on atom interferometry which is optimized for mobility and mechanical stability. This setup will open up the possibility to perform on-site high precision measurements of local gravity. We report on the status of the project and its subsystems including a rack-mounted cooling and raman laser system.

This gravimeter is developed within the FINAQS project, a collaboration of five European research groups that aims at developing new atomic quantum sensors.
