The DIRAC experiment at CERN aims to measure the lifetime of the pionium atom (A_2π), a π^+π^- bound state with an accuracy of 10 experimental setup consists of a high precision magnetic double arm spectrometer, located at the high intensity proton beam of the CERN Proton Synchrotron. This measurement will provide - in a model independent way - the S-wave pion scattering length difference |a_0 - a_2| with 5
