Characterization of a prototype for the electromagnetic calorimeter of the Mu2e experiment


The Mu2e experiment at Fermilab searches the neutrinoless conversion of the muon into electron in the field of an Aluminum nucleus. The observation of this process would be a proof of the Charged Lepton Flavor Violation (CLFV). In case of no observation, the upper limit will be set to R_(μe) < 6×10^(−17) @ 90% CL, improving by a factor of 4 the previous best determination. The Mu2e detector apparatus consists of a straw tubes tracker that will measure the electrons momentum, and an electromagnetic calorimeter that provides a tracking-independent measurement of the electron energy, time and position. In this paper, we describe the baseline project of the EMC and present results in terms of performances and R&D.

The authors are grateful to many people for the successful realization of the matrix. In particular, we thank all the LNF mechanical shop for the realization of the support and the APD boxes. We also thank the whole BTF and MAMI staffs for providing the beam time and helping us in getting a smooth running period.
