The active diamond target of the PADME experiment

Abstract

PADME (Positron Annihilation into Dark Matter Experiment) at the Laboratori Nazionali di Frascati of the INFN is an experiment that searches for the gauge boson of the dark sector, the dark photon A´, produced in the annihilation between a positron of a beam with an electron of a target. The PADME Lecce group designed and assembled the active diamond target, the heart of the experiment that is working since September 2018 in the beamline in vacuum in stable conditions, without any external interventions.
