Description
Neutrino experiment results suggest that flavor can be violated for neutral leptons through neutrino oscillation, but no flavor violation has been measured for charged leptons yet. The COMET experiment at J-Parc searches for coherent neutrinoless conversion of a muon to an electron in muonic atoms ( μ- + N(A,Z) → e- + N(A,Z) ). The goal for COMET Phase-I is to reach an experimental sensitivity of $10^{−15}$ and then a sensitivity of $10^{−17}$ for the Phase-II, improving existing limits by a factor 10,000. To reach the expected sensitivity, the detector needs to be protected from the atmospheric muons, which are the main background source. For this purpose, a sub detector called Cosmic Ray Veto (CRV) is needed to operate in this very high radiation environment.
