Status update of the Mu3e Tile Detector — Konrad Briggl, •Hannah Klingenmeyer, Yonathan Munwes, Wei Shen, Tiancheng Zhong, and Hans-Christian Schultz-Coulon — Kirchhoff-Institut für Physik, Universität Heidelberg
The Mu3e experiment, which will be installed at the Paul Scherrer Institute (PSI) in Switzerland, is designed to search for the lepton-flavour violating decay µ → eee with a target sensitivity of 10−16. In order to determine the vertex of the three decay electrons, precise space and time measurements are required. Dedicated tracking and timing detectors are being developed for this purpose. One of the timing systems is the Mu3e Tile Detector, which allows precise timing of individual electrons with a resolution below 100 ps.
The Mu3e Tile Detector, which is currently in the pre-production phase, uses plastic scintillator tiles and silicon photomultipliers that are read out by the MuTRiG ASIC, also developed in Heidelberg. In this talk, a comprehensive overview of the current detector status is given; details on the pre-production process and first performance tests of the detector prototype are presented. In particular, the production steps, the developed production tools, and quality assurance are discussed.
