Identification of photons and particles in the segmented electromagnetic calorimeter TAPS

The algorithms devellped for the identification of one and two hard-photon events detected with TAPS are presented. After a presentation of the energy and time calibrations, the identification of single module events and the shower reconstruction, special emphasis is given to the rejection of the background generated by cosmic rays, π0 decay and e± conversion pairs. The effect of discontinuous showers is also discussed. The method was tested on data taken with TAPS at GANIL for heavy-ion collisions at energies of several tens of A MeV.
