Description
The Mu2e experiment is designed to search for the charged-lepton-flavor-violating
process, $\mu^-$ to a $e^-$, with unprecedented sensitivity. The single 105-MeV
electron that results from this process can be mimicked by electrons produced by
cosmic-ray muons traversing the detector. An active veto detector surrounding
the apparatus is used to detect incoming cosmic-ray muons. To reduce the backgrounds
to the required level it must have an efficiency of about 99.99% as well as
excellent hermeticity. The detector consists of four layers of scintillator counters,
each with two embedded wavelength-shifting fibers, whose light is detected by
silicon photomultipliers. The design and expected performance of the cosmic ray
veto detector will be described.
