The NA48/2 experiment at CERN performed a high precision study of direct CP-violation in charged kaon decays into three pions, using an upgraded NA48 setup and a novel design for simultaneous unseparated K± beams. The asymmetry in the Dalitz plot linear slopes Ag=(g+−g−)/(g++g−) is measured to be by studying decays and by studying decays. The unique K± simultaneuos beam system, the design of the detectors and the method of analysis provide good control of the instrumental charge asymmetries and allow to keep the precision of the result limited by statistics, reaching accuracy one order of magnitude better than in previous experiments. The large amount of charged kaon decays collected allow also precision measurements of several rare decay processes.
