Underground operation at best sensitivity of the mobile LNE-SYRTE cold atom gravimeter

Underground operation at best sensitivity of the mobile LNE-SYRTE Cold Atom Gravimeter

Low noise underground environments offer conditions allowing to assess ultimate performance of high sensitivity sensors such as accelerometers, gyrometers, seismometers... Such facilities are for instance ideal for observing the tiny signals of interest for geophysical studies. Laboratoire Souterrain à Bas Bruit (LSBB) in which we have installed our cold atom gravimeter, provides such an enviro...

Short Communication

We report the direct comparison between the stabilities of two mobile absolute gravimeters of different technology: the LNE-SYRTE Cold Atom Gravimeter (CAG) and FG5X#216 of the Université du Luxembourg. These instruments rely on two different principles of operation: atomic and optical interferometry. The comparison took place in the Walferdange Underground Laboratory for Geodynamics in Luxembo...

iSense: A Portable Ultracold-Atom-Based Gravimeter

We present iSense, a recently initiated FET project aiming to use Information and Communication Technologies (ICT) to develop a platform for portable quantum sensors based on cold atoms. A prototype of backpack-size highprecision force sensor will be built to demonstrate the concept. © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V.
