First gravity measurements using the mobile atom interferometer GAIN

We present the compact Gravimetric Atom Interferometer (GAIN), based on laser-cooled 87 Rb atoms, and discuss its first measurements of the local gravitational acceleration. In this context, we also describe an active vibration isolation system and a tip-tilt stage, which allow for a suppression of...

Description
Summary:We present the compact Gravimetric Atom Interferometer (GAIN), based on laser-cooled 87 Rb atoms, and discuss its first measurements of the local gravitational acceleration. In this context, we also describe an active vibration isolation system and a tip-tilt stage, which allow for a suppression of vibrational noise and systematic effects like the Coriolis force due to Earth’s rotation.
