Description

Mu3e is an experiment for the search for the charged lepton flavour violating decay $\mu \rightarrow \mathrm{eee}$ with a single event sensitivity of $10^{-16}$, which is an improvement of 4 orders of magnitude over the current limit of $B < 10^{-12}$ (90% CL, SINDRUM, 1988).
This poster explains the general detector concept and lays focus on the scintillating fibre sub-detector. High muon stopping rates of up to $10^8 \mu/s$ call for precise timing measurements to suppress combinatorial backgrounds (pileup). The scintillating fibre sub-detector (in combination with a scintillating tile sub-detector) makes for combinatorial background suppression by two orders of magnitude.
