Description

We present a compact scintillating fiber timing detector developed for the Mu3e experiment. Mu3e is a novel experiment for the search of the charged lepton flavor violating neutrinoless muon decay mu -> eee. Mu3e is about to start taking data at PSI using the world's most intense continuous surface muon beam. The scintillating fiber detector is formed by staggering three layers of 250 um scintillating fibers. The fiber ribbons are coupled at both ends to multi-channel silicon photo-multiplier arrays which are read out with the MuTRiG ASIC especially developed for this experiment.

In particular, we will focus on the performance of this very thin (thickness < 0.2% of a radiation length) fiber detector in terms of the achieved timing resolution of ~250 ps, efficiency of ~97%, and spatial resolution of ~100 um, including the time calibration of the detector. We will also discuss the operation and performance of the MuTRiG ASIC used for reading out the ~3000 channels of the fiber detector.
