The following stage of the experiment (NA48/1) was carried out in 2002 and was devoted to high precision study of rare decays of neutral kaons and hyperons. The next stage (NA48/2) was carried out in 2003–2004 and was dedicated to a large programme of studies of properties of charged kaons, including the search of direct CP violation, studies of rare decays of the charged kaon, and low-energy QCD using final state rescattering.
