The DIRAC experiment aims to measure the lifetime of π + π -atoms in the ground state with 10% precision, using the 24 GeV/c proton beam of the CERN Proton Synchrotron. As the value of the above lifetime of order 10 -15 s is dictated by a strong interaction at low energy, the precise measurement of
