Abstract
The PADME experiment at the Laboratori Nazionali di Frascati of the INFN searches for a hypothetical dark photon , produced in the annihilation between a positron of a beam with an electron of a target. The target is an active component of the experiment; it consists of a thin and large size diamond detector with a pattern of graphitic strips on both sides acting as ohmic electrodes for detector polarization and signal readout. In this paper the operation and performance of the active diamond target, as observed in the first PADME physics run, are reported.| File | Dimensione | Formato | |
