TL;DR
This paper discusses a planned experiment at CERN to measure the hyperfine structure of antihydrogen in a beam, aiming to test CPT symmetry with high precision.
Contribution
It proposes a novel experimental approach to measure antihydrogen's hyperfine structure using a beam at CERN, which has not been done before.
Findings
Design of the experimental setup at CERN
Expected high-precision measurement of antihydrogen hyperfine splitting
Potential to improve tests of CPT symmetry
Abstract
A measurement of the hyperfine structure of antihydrogen promises one of the best tests of CPT symmetry. We describe an experiment planned at the Antiproton Decelerator of CERN to measure this quantity in a beam of slow antihydrogen atoms.
