Description

The ASACUSA collaboration at the Antiproton Decelerator of CERN aims at a precise measurement of the ground-state hyperfine splitting of antihydrogen, which promises to be one of the most sensitive tests of CPT symmetry. In a Rabi type setup, a dedicated antiproton-positron mixing trap produces antihydrogen atoms, which pass a tunable spin-flip microwave cavity and a sextupole magnet for spin-flip detection, before they are counted in a tracking detector [1].

In my presentation, I will give an overview of the current status of the experiment, as well as the achievements made during the most recent antiproton run at CERN.
