The Positron Annihilation into Dark Matter Experiment (PADME) aims to search for the production of a dark photon in the process e+ e− → A'γ. It uses the ~500 MeV positron beam, provided by the LINAC of the Frascati National Laboratory of INFN, interacting with the electrons of a thin target.
The primary beam crosses an active diamond target and if it does not interact, it is bent by a dipole magnet towards a pixel beam-monitor. If Bremsstrahlung interaction causes the positrons to lose more than 50 MeV of energy, the magnet bends them into the acceptance of a charged particle detector providing a veto signal. In case of annihilation, dark photons are searched as a missing mass signal among the final states with a single photon. Therefore, the main component of the setup is a calorimetric system consisting of two stations.
In the talk it will be given an overview of the apparatus with details on the performance of each detector component.
