The ASACUSA CUSP collaboration at the Antiproton Decelerator (AD) of CERN is
planning to measure the ground-state hyperfine splitting of antihydrogen using
an atomic spectroscopy beamline. We describe here the latest developments on
the spectroscopy apparatus developed to be coupled to the antihydrogen
production setup (CUSP).Comment: Proceedings of the 11th International Conference on Low Energy
Antiproton Physics (LEAP 2013) held in Uppsala, Sweden, 10 to 15 June, 201
