A High-efficiency Cosmic Ray Veto Detector for the Mu2e Experiment

Not scheduled


Ben Barton (Virginia) Danny Mills (Virginia)


The Mu2e experiment at Fermilab will search for the charged lepton flavor violating process of coherent muon-to-electron conversion in the presence of a nucleus with a sensitivity four orders of magnitude beyond current limits. The experiment will have a single event sensitivity of about 3×10^−17 while limiting the total background to about 0.5 events. One potential background is due to cosmic-ray muons producing an electron that is indistinguishable from signal within the Mu2e apparatus. The cosmic-ray-veto system of the Mu2e experiment is tasked with vetoing cosmic-ray-induced backgrounds with high efficiency, without inducing significant dead time and while operating in a high-intensity environment. The design of the cosmic-ray-veto system will be discussed.
