The experiment was started at 1999 and aims 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 very challenging task in light of time and precision of measurement

The Czech group participated on production of several detectors e.g. Horizontal Hodoscope or Heavy Gas Cherenkov Counter. Further this we are responsible for calibration of measured data, study of response of Ionization Hodoscope and another analyses needed for evaluation of final results.
