The LYSO crystal calorimeter for the Mu2e experiment


The Mu2e experiment at Fermilab searches the neutrino-less conversion of the muon into electron in the field of an Aluminum nucleus. If such a process will be observed, it will be a proof of the charged-lepton-flavor-violation (cLFV), otherwise Mu2e will set an upper limit of R_μe < 6 × 10^(−17) @ 90% C.L. (which represents an improvement by 3–4 order of magnitude over the existing limit). The Mu2e detector apparatus consists of a magnetic spectrometer, devoted to the measurement of the electrons momentum, and an electromagnetic calorimeter (EMC) which provides an independent measurement of the electron energy, time and position, used for validating or rejecting candidate tracks selected by the tracking system. In this paper, we describe the baseline project of the EMC and present results in terms of performances and R&D.
