AEGIS at CERN: Measuring Antihydrogen Fall

TL;DR

The AEGIS experiment at CERN aims to test fundamental physics principles by measuring the gravitational fall of antihydrogen, providing the first test of the Weak Equivalence Principle with antimatter.

Contribution

This work introduces a novel experimental approach to measure antihydrogen's free fall, testing the WEP with antimatter for the first time.

Findings

Antihydrogen beam formation at CERN

Measurement of antihydrogen fall using a Moire deflectometer

First test of WEP with antimatter

Abstract

The main goal of the AEGIS experiment at the CERN Antiproton Decelerator is the test of fundamental laws such as the Weak Equivalence Principle (WEP) and CPT symmetry. In the first phase of AEGIS, a beam of antihydrogen will be formed whose fall in the gravitational field is measured in a Moire' deflectometer; this will constitute the first test of the WEP with antimatter.
