Interferometers with Bose-Einstein condensates (BECs) enable a very precise measurement of inertial forces like gravity. Potential applications can be in ground and space-borne geodesy. A lower size, weight, and power consumption of these sensors can be realized by using atom chips. The latter enables the creation of a high flux of delta-kick collimated BECs bringing in reach an unprecendented, low measurement uncertainty.
In this poster, we will present a concept to further reduce the sensor head to about shoe-box size. With a novel atom chip combined with the implementation of a relaunch scheme, an innovative single-beam quantum gravimeter is envisaged. The further miniaturization and reduction of complexity of the sensor head are the key features to improve the transportability and ease the in-field operation of the
quantum gravimeter.
