Description
The AEgIS experiment at CERN is primarily designed to investigate the gravitational interaction between matter and antimatter by measuring the free fall of antihydrogen in a field-free environment. Its core objective is to test the weak equivalence principle for antimatter using a pulsed antihydrogen beam and high-precision spatial detection. In parallel, AEgIS pursues a range of complementary research goals, including the physics of positronium in strong magnetic and cryogenic environments, as well as the formation and spectroscopy of exotic atoms involving antiprotons and negative ions.
In 2024, AEgIS completed a comprehensive set of upgrades to its experimental infrastructure, significantly enhancing the stability, automation, and performance of the apparatus. Key developments included the installation of a forward extraction beamline enabling antihydrogen transport beyond the magnetic confinement region, the integration of a higher-activity positron source, and improved control of Rydberg laser excitation. These advancements facilitated extended data-taking runs with increased antihydrogen yield and reproducibility. On the physics front, progress was made in positronium production and excitation under cryogenic, high-field conditions, as well as in the time-of-flight spectroscopy of ions from antiproton annihilation. Concurrently, the R&D program advanced the implementation of a moiré deflectometer for gravity measurements, developed position- and time-sensitive detection systems, and explored techniques for handling negative ions and portable antiproton traps to support future precision studies of exotic atoms.
