AEgIS (Antimatter Experiment: gravity, Interferometry, Spectroscopy), AD-6, is an experiment to measure directly the effect of Earth's gravitational field on antihydrogen atoms with significant precision. Indirect bounds that assume the validity of, for example, the universality of free fall, the Weak Equivalence Principle or CPT symmetry also in the case of antimatter constrain an anomalous gravitational behavior to a level where only precision measurements can provide answers. Vice versa, antimatter experiments with sufficient precision are essential to validate these fundamental assumptions. AEgIS was originally proposed in 2007. Construction of the main apparatus was completed in 2012. Since 2014, two laser systems with tunable wavelengths (few picometer precision) and synchronized to the nanosecond for specific atomic excitation have been successfully commissioned.
In 2024, AEgIS achieved the first demonstration of laser cooling of a gas composed of positronium atom. In April 2025, AEgIS announced a new antimatter detector made from modified smartphone cameras. This detector achieved the highest pixel count of any imaging detector to date.
