Description
Mu3e is a novel experiment under preparation at PSI searching for lepton flavor violation in the neutrinoless $\mu \rightarrow eee$ decay. To suppress accidental backgrounds a scintillating fiber timing detector read out with multi-channel SiPM arrays at both ends has been developed. The SiPM arrays will be exposed to a very high flux of low energy positrons (E ∼ 10 to 50 MeV) from $\mu$ decays, which cause much more damage than MIPs. The expected dose during Phase I of the experiment is estimated around 10$^{11}$ neutron equivalent / cm$^2$. In this talk we will present our experience with the irradiated multi-channel SiPM arrays exposed at different doses and operated at different temperatures.
