Abstract | <p>In this review, we describe a planned experiment of the Atomic Spectroscopy And Collisions Using Slow Antiprotons (ASACUSA) collaboration at CERN to test CPT symmetry via atomic beam spectroscopy of the ground-state hyperfine splitting of antihydrogen using a cusp trap. The cusp trap which consists of a superconducting anti-Helmholtz coil and a stack of ring electrodes, is expected to produce a spin-polarized antihydrogen beam. Recently, the ASACUSA collaboration succeeded in producing antihydrogen atoms in the cusp trap and extracting an antihydrogen beam. This paves the way towards precision in-flight spectroscopy of the antihydrogen atom.</p> <p> </p> |
