MIGA: STUDYING GRAVITY WITH AN HYBRID ATOM-OPTICAL INTERFEROMETER |
|
Abstract |
We are building a new, hybrid detector that couples laser and matter-wave interferometry to study sub Hertz variations of the strain tensor of space-time and gravitation. Using a novel approach exploiting a set of atomic interferometers simultaneously manipulated by the resonant optical field of a 200 m cavity, this instrument will allow at the same time a better understanding of the evolution of the gravitational field and a new tool for gravitational waves (GW) detection. Indeed, each atomic ensemble of the antenna will be manipulated by cavity enhanced Bragg pulses to create an atom interferometer that will simultaneously read out motion of the cavity, GW and inertial effects. This new infrastructure will be embedded into the French LSBB underground laboratory, ideally located away from major anthropogenic disturbances and benefitting from very low background noise. We will report about the details of the instruments and the status of the project. |
