Measuring $\bar{g}$ with ${\rm AE\bar{g}IS}$, progress and perspectives

2014
experiment's main goal is to measure the local gravitational accelerationof antihydrogenand thus perform a direct test of the weak equivalenceprinciple with antimatter. In the first phase of the experiment the aim is to measure with 1% relative precision. This paper presents the antihydrogenproduction method and a description of some components of the experiment, which are necessary for the gravity measurement. Current status of the experimental apparatus is presented and recent commissioning results with antiprotonsare outlined. In conclusion we discuss the short-term goals of the collaboration that will pave the way for the first gravity measurement in the near future.
