Abstract

We will present the last developments on MIGA, a 150 m horizontal gravity-gradiometer being built underground as a demonstrator for gravitational wave detection using atomic sensors. We demonstrated the multi-photon Bragg diffraction in a prototype optical resonator 80 cm long, where we made use of the cavity modal structure to boost the atom optics efficiency. We will report on the work progress of the large baseline infrastructure.
