The MAGIA experiment is designed to measure the Newtonian gravitational constant G using atom interferometry. A double differential measurement of the gravitational force produced by heavy source masses on two clouds of atoms allows the determination of G. We present the general idea and actual status of the experiment
We are building a cold atom absolute gravimeter based on atom interferometry with a projected accuracy of 10-9 g. It is part of the French watt balance project intending to link the SI Kg unit to fundamental constants
