GG-TOP a multidisciplinary atom interferometry project — •Alexander Niggebaum, Tristan Valenzuela, Vincent Boyer, and Kai Bongs — Midlands Ultracold Atom Research Centre, School of Physics and Astronomy, University of Birmingham, Edgbaston, Birmingham B15 2TT, United Kingdom

We present the GG-TOP project, an holistic research program in the field of atom interferometry gravity gradiometry. GG-TOP is a joint effort by physicists, civil engineers and archaeologists to develop an applications driven full tensor gravity sensor based on cutting-edge atom interferometry. The project aims to develop two sensors. On the one hand, we will build a roughed gravity gradiometer capable of field deployment for applications in Civil Engineering and Archaeology. Its sensitivity should allow the detection small underground voids or other high density-contrast features located at depths in the range of 1 to 10 meters. On the other hand we will develop a laboratory sensor where we will seek the ultimate sensitivity using the latest technologies (eg. large momentum transfer, expansion suppression of cold atom clouds, ...).
