Impact of direct digital synthesizer finite resolution on atom gravimeters
R Karcher, Franck Pereira dos Santos, S Merlet
We report on the study of the impact of the finite resolution of the chirp rate applied on the frequency difference between the Raman lasers beamsplitters onto the phase of a free…

Improving the accuracy of atom interferometers with ultracold sources
R Karcher, A Imanaliev, S. Merlet +1
We report on the implementation of ultracold atoms as a source in a state of the art atom gravimeter. We perform gravity measurements with 10 nm/s 2 statistical uncertainties in a…
