Abstract

The Mu2e experiment at Fermilab seeks to probe physics beyond the standard model by observing direct neutrino-less conversion of muons to electrons, and it proposes to do this with a sensitivity that is four orders of magnitude better than any previous experiment. An extremely high sensitivity experiment requires well controlled backgrounds. Interactions of cosmic ray muons, within the experimental hall, can give rise to backgrounds that mimic or fake a conversion signal. Thus, it is critical for the success of the experiment to tag these muons with 99.99% efficiency. A scintillator-MPPC Cosmic Ray Veto (CRV) Detector covering most of the detector hall is in its final prototyping stages to achieve this stringent performance goal. Further challenges arise from the fact that the CRV will sit in a rich beam-induced background environment over the multi-year high-intensity operation of Mu2e. The present work is a study of the performance of multi-pixel photon counters used in the CRV detector as a function of the integrated radiation doses expected throughout the lifetime of the experiment.
