High sensitivity cold atom gyroscope

We present the new cold atom gyroscope experiment developed at SYRTE since 2009. The experiment is based on a fountain configuration and a four light pulse atom interferometer which allows to reach a Sagnac area of at least 11 cm². We demonstrated a gyroscope stability of 3 nrad·s⁻¹ after 1 000 s of integration, which represents the state of the art for cold atom gyroscopes. Here we describe the main elements of the setup and the near future evolutions of the experiment to achieve better sensitivity levels.
