Abstract
| AE¯gIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy)
is an experiment at the Antiproton Decelerator (AD) facility at CERN
whose goal is to study the asymmetry between matter and antimatter and, in particular,
the effect of the Earth’s gravitational field on antihydrogen ( ¯ H). During
the 2018 run, ¯H
was formed, leading into considerable gain of knowledge on the
processes involved. Therefore, in the last two years, during CERN LS2, multiple
upgrades to the experiment have been carried out, spanning from new degraders,
a new ¯H
formation trap scheme, an entirely new control system, a more efficient
positronium (Ps) converter, and more efficient sensors. All this work is necessary
towards the goal of creating the first pulsed beam of neutral ¯H, which will enable
inertial studies on antihydrogen with high degrees of precision. This contribution
presents different upgrades, their validation with the antiprotons beam, and the
further developments foreseen in the future. |
