    "abstract": "We developed a gravity-gradiometer based on atom interferometry for the\ndetermination of the Newtonian gravitational constant \\textit{G}. The\napparatus, combining a Rb fountain, Raman interferometry and a juggling scheme\nfor fast launch of two atomic clouds, was specifically designed to reduce\npossible systematic effects. We present instrument performances and show that\nthe sensor is able to detect the gravitational field induced by source masses.\nA discussion of projected accuracy for \\textit{G} measurement using this new\nscheme shows that the results of the experiment will be significant to\ndiscriminate between previous inconsistent values.",
