The central goal of the project is the experimental realization of a setup which allows the direct and quantitative measurement of the gravitational acceleration of antimatter - a Moiré-deflectometer for antimatter. The setup is part of the general setup within the collaboration AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) at CERN where an anti-hydrogen beam will be realized. The defined goal is the measurement of gravitation acceleration of anti-hydrogen till end of 2015 with a precision of 5-10%. This will be the first direct test of the weak equivalence principle without additional assumptions. With the further development and improvement of the Moiré-deflectometer, a simple and robust apparatus will become available which has a projected sensitivity to gravitational acceleration allowing for an application in geology.

该项目的中心目标是实验实现一个装置，它可以直接和定量地测量反物质的引力加速度——一个反物质的莫伊尔变矩仪。该装置是欧洲核子研究中心合作AEgIS（反物质实验：重力，干涉测量，光谱学）总体装置的一部分，反氢束将在那里实现。确定的目标是到2015年底测量反氢的引力加速度，精度为5-10%。这将是对弱等效原理的第一个没有附加假设的直接检验。随着莫伊尔变矩仪的进一步发展和改进，一种简单而坚固的仪器将成为可能，它对重力加速度具有预期的灵敏度，从而允许在地质学中应用。
