The experiment started in 1999 and its aim is to measure the lifetime of π⁺ π^- and πK atoms in the ground state using the 24 GeV/c proton beam of the CERN Proton Synchrotron. This is a very challenging task requiring quite a lot of time and high precision of measurement

The Czech group participated in production of several detectors, e.g. Horizontal Hodoscope or Heavy Gas Cherenkov Counter. We are further responsible for calibration of measured data, study of the response of Ionization Hodoscope and another analyses needed for establishing final results.
