Sumario:The Scintillator Pad Detector belongs to the ECAL system and has to separate photons and electrons at the level-0 of the ECAL trigger. It has its own read-out system and it is positioned just. before the preshower (PS). '['his note reports on the test beam for the Sl'D and shows its design, klonte Carlo simulation and results. The tagged photon bea.m allowed testing photon signals at the SPD. These signals are mainly due to pair production inside the scintillator and to charged particles generated in the shower at PS and ECAL (backsplash). The results show that both effects do not introduce large inefficiencies in photon-electron separation.
