| Abstract | The AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) experiment, located at the Antimatter Factory at CERN, aims to study the asymmetry between matter and antimatter. In particular, its first goal is to measure the effect of gravity on antimatter. The method chosen is to determine the fall of a pulsed beam of anti-hydrogen, caused by the Earth's gravitational field, by mean of a moiré deflectometer. In this contribution the new anti-hydrogen production scheme is presented, together with the improvements that the experimental setup underwent in the last years, deemed necessary in order to reach an antihydrogen flux with the characteristics needed to obtain a precise gravity measurement. Last, the first technical results are described and the future steps outlined. |
