AEgIS (Antimatter Experiment: Gravity, Interferometry, Spec-troscopy) is an experiment at the Antiproton Decelerator (AD) facility at CERN whose goal is to study the asymmetry between matter and antimatter and, in par-ticular, the effect of the Earth's gravitational field on antihydrogen (Hbar ). During the 2018 run, Hbar 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 Hbar 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 Hbar , 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.

Abstract
AEgIS (Antimatter Experiment: Gravity, Interferometry, Spec-troscopy) is an experiment at the Antiproton Decelerator (AD) facility at CERN whose goal is to study the asymmetry between matter and antimatter and, in par-ticular, the effect of the Earth's gravitational field on antihydrogen (Hbar ). During the 2018 run, Hbar 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 Hbar 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 Hbar , 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.File | Dimensione | Formato | |
