Description
We report the realization of a large scale gravity antenna based on matter-wave interferometry, the MIGA project. This experiment consists in an array of cold Rb sources correlated by a 150 m long optical cavity. MIGA is in construction at the LSBB underground laboratory, a site that benefits from a low background noise and is an ideal premise to carry out precision gravity measurements. The MIGA facility will be a demonstrator for a new generation of GW detector based on atom interferometry that could open the infrasound window for the observation of GWs. We describe here the status of the instrument construction, focusing on the infrastructure works at LSBB and the realization of the vacuum vessel of the antenna.
