Abstract:

After the first production of cold antihydrogen about ten years ago, second-generation experiments whose aim it is to measure the fundamental properties of this anti-atom are beginning to become operational. The AEGIS experiment will test the weak equivalence principle of General Relativity by measuring the gravitational interaction between matter and antimatter with the help of a pulsed, cold antihydrogen beam. The vertical deflection of antihydrogen atoms in the gravitational field of the Earth will be determined with a moiré deflectometer. In the present paper, the principle of the experiment will be reviewed and its present status will be presented.
