Description
The field of atom optics has seen tremendous development during the past decades. Tools and methods from this field have evolved from proof-of-principle experiments to reliable instruments with unprecedented precision and are now utilized to tackle fundamental questions – also in different fields of physics. The AEgIS collaboration has used such a tool known as moiré deflectometer, an instrument that can be described with classical particle trajectories, to measure electromagnetic forces on antiprotons. The ultimate goal of this ongoing effort is to build a device for future measurements of antihydrogen’s gravitational acceleration in Earth’s field. Towards this challenging goal, one is interested in increasing the sensitive of the measuring apparatus. A promising way is to push the moiré deflectometer into the wave-regime, where it can be regarded as a Talbot-Lau interferometer. Realizing such an interferometer for antiprotons would represent an important, intermediate experimental step.
