PADME (Positron Annihilation into Dark Matter Experiment) is an experiment that will search for the production of a dark photon A' from the annihilation of a positron beam on a thin diamond target. It will use the 550 MeV positron beam of the Beam Test Facility (BTF) of the Laboratori Nazionali di Frascati (LNF) of INFN. According to the PADME design, the region of sensitivity is M-A' <= 23.7 MeV/c(2) and epsilon(2) > 10(-6), where M-A' and epsilon are the dark photon mass and the A'gamma mixing parameter.This paper presents the status of the active diamond target, in particular the assembly of two 32 channel targets of polycrystalline Chemical Vapor Deposition (CVD) diamond, one with graphitic strips and another with traditional CrAu strips.

Abstract
PADME (Positron Annihilation into Dark Matter Experiment) is an experiment that will search for the production of a dark photon A' from the annihilation of a positron beam on a thin diamond target. It will use the 550 MeV positron beam of the Beam Test Facility (BTF) of the Laboratori Nazionali di Frascati (LNF) of INFN. According to the PADME design, the region of sensitivity is M-A' <= 23.7 MeV/c(2) and epsilon(2) > 10(-6), where M-A' and epsilon are the dark photon mass and the A'gamma mixing parameter.This paper presents the status of the active diamond target, in particular the assembly of two 32 channel targets of polycrystalline Chemical Vapor Deposition (CVD) diamond, one with graphitic strips and another with traditional CrAu strips.| File | Dimensione | Formato | |
