AEgIS experiment at CERN (European Organization for Nuclear Research). The AEgIS experiment (Antimatter Experiment: gravity, Interferometry, Spectroscopy) is designed to examine the effects of gravity on antimatter. Antihydrogen is produced by mixing positrons with antiprotons from the Antiproton Decelerator facility. An antihydrogen pulsed beam is shot horizontally through a vacuum tube in order to measure how far it falls in a given amount of time. Antihydrogen is chosen for this experiment because it is minimally affected by magnetic or electric fields, making it easier to probe any discrepancies.
