Continuous g monitoring with atom interferomerty

Résumé

We present our cold atom interferometer using Rb-87 developed to perform absolute g measurement similar to the Stanford experiment [1] which used Cs. The device and the measurement protocol are described and an example of 12 days continuous measurement is presented. This measurement shows the capabilities of the instrument in the frame of a watt balance experiment, avoiding the use of environmental models to extrapolate the accurate value of g needed to link the Planck constant to the kilogram [2]. Limits in terms of sensitivity and accuracy are finally presented.
