Measuring 
with 
, progress and perspectives
Abstract
experiment's main goal is to measure the local gravitational acceleration of antihydrogen 
and thus perform a direct test of the weak equivalence principle with antimatter. In the first phase of the experiment the aim is to measure 
with 1% relative precision. This paper presents the antihydrogen production 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 antiprotons are 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.
