Abstract

The high precision and scalable technology offered by atom interferometry has the opportunity to profoundly affect gravity surveys, enabling the detection of features of either smaller size or greater depth. While such systems are already starting to enter into the commercial market, significant reductions are required in order to reach the size, weight and power of conventional devices. In
this article the potential for atom interferometry based gravimetry is assessed, suggesting that the key opportunity resides within the development of gravity gradiometry sensors to enable drastic improvements in measurement time. To push forward in realising more compact systems, techniques have been pursued to realise a highly portable magnetooptical trap system, which represents the core package of an atom interferometry system. This can create
clouds of 107 atoms within a system package of 20 litres and 10kg, consuming 80W of power.
