Транспортируемый гравиметр на холодных атомах разработки LNE-SYRTE: работа в подземных условиях в режиме наилучшей чувствительности
Abstract
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 environment. We report here the best short term sensitivity ever obtained without any ground vibration isolation system with such an instrument: 10-8 m.s-2 in 100 s measurement time.
