Description

The Mu2e experiment at Fermilab aims to search for the neutrinoless coherent conversion of a muon to an electron, in the field of an aluminum nucleus. Observation of this process would be direct evidence of Charged Lepton Flavor Violation (CLFV), a phenomenon that probes physics beyond the Standard Model. This experiment will improve the current sensitivities by four orders of magnitude. Mu2e uses a state-of-the-art crystal calorimeter which consists of 1348 pure CsI crystals readout by UV-extended SiPMs and fast electronics (2 per crystal). The calorimeter comprises two annular disks that are placed 70 cm apart. In this talk, I summarize the absolute energy calibration of two calorimeter disks using deuterium-tritium source activated radioactive liquid fluorinert. This will include the mechanical structure, software and fitting analysis used to calculate calibration constants.
