Calibration of a superconducting gravimeter with an absolute atom gravimeter
S. Merlet, P. Gillot, B. Cheng +4
We present a 27-days long common view measurement of an absolute cold atom gravimeter (CAG) and a relative iGrav superconducting gravimeter, which we use to calibrate the iGrav sca…
Coherent population trapping in a Raman atom interferometer
Bing Cheng, Pierre Gillot, Sébastien Merlet +1
We investigate the effect of coherent population trapping (CPT) in an atom inter-ferometer gravimeter based on the use of stimulated Raman transitions. We find that CPT leads to si…
Metrology with Atom Interferometry: Inertial Sensors from Laboratory to Field Applications
Bess Fang, Indranil Dutta, Pierre Gillot +8
Developments in atom interferometry have led to atomic inertial sensors with extremely high sensitivity. Their performances are for the moment limited by the ground vibrations, the…
Influence of chirping the Raman lasers in an atom gravimeter: phase shifts due to the Raman light shift and to the finite speed of light
B. Cheng, P. Gillot, S. Merlet +1
We present here an analysis of the influence of the frequency dependence of the Raman laser light shifts on the phase of a Raman-type atom gravimeter. Frequency chirps are applied…
Effective velocity distribution in an atom gravimeter: effect of the convolution with the response of the detection
Tristan Farah, Pierre Gillot, Bing Cheng +3
We present here a detailed study of the influence of the transverse motion of the atoms in a free-fall gravimeter. By implementing Raman selection in the horizontal directions at t…
