AEgIS experiment: Measuring the acceleration g of the earth's gravitational field on antihydrogen beam
Original language description
The AEgIS experiment [1] aims at directly measuring the gravitational acceleration g on a beam of cold antihydrogen (H) to a precision of 1%, performing the first test with antimatter of the (WEP) Weak Equivalence Principle. The experimental apparatus issited at the Antiproton Decelerator (AD) at CERN, Geneva, Switzerland. After production by mixing of antiprotons with Rydberg state positronium atoms (Ps), the H atoms will be driven to fly horizontally with a velocity of a few 100 ms-1 for a path length of about 1 meter. The small deflection, few tens of ?m, will be measured using two material gratings (of period ~ 80 ?m) coupled to a position-sensitive detector working as a moiré deflectometer similarly to what has been done with matter atoms [2]. The shadow pattern produced by the H beam will then be detected by reconstructing the annihilation points with a spatial resolution (~ 2 ?m) of each antiatom at the end of the flight path by the sensitive-position detector.
