We report on the characterization of a dual cloud atom interferometer for gravity gradient measurements using third-order Bragg diffraction as atom optical elements. We study the dependence of the contrast and the gradiometer phase angle against the relevant experimental parameters and characterize the instrument sensitivity. We achieve a sensitivity to gravity gradient measurements of 2.6 × 10 −8 s −2 (26 E) after 2000 s of integration time.

Abstract
We report on the characterization of a dual cloud atom interferometer for gravity gradient measurements using third-order Bragg diffraction as atom optical elements. We study the dependence of the contrast and the gradiometer phase angle against the relevant experimental parameters and characterize the instrument sensitivity. We achieve a sensitivity to gravity gradient measurements of 2.6 × 10 −8 s −2 (26 E) after 2000 s of integration time.File in questo prodotto:
