Test of weak equivalence principle with antimatter

该项目的中心目标是实验实现一种装置，可以直接和定量测量反物质的重力加速度-反物质的莫尔偏转仪。该装置是CERN合作AEgIS（反物质实验：重力，干涉测量，光谱学）中的一般装置的一部分，其中将实现反氢束。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%。这将是第一次直接测试弱等效原理没有额外的假设。随着莫尔偏折仪的进一步发展和改进，一种简单而坚固的设备将变得可用，该设备对重力加速度具有预计的灵敏度，从而允许在地质学中应用。

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.
