Mu3e Tile Detector Prototype — •Tiancheng Zhong, Yonathan Munwes, Hannah Klingenmeyer, Wei Shen, and Hans-Christian Schultz-Coulon for the Mu3e collaboration — Kirchhoff-Institut für Physik, Universität Heidelberg, Heidelberg 69120, Germanny
The Mu3e experiment is designed to search for the charged Lepton Flavour Violation (cLFV) decay µ+ → e+ e+ e− with detector sensitivity of 10−16. The observation of this decay would be a clear signal for new physics beyond the Standard Model (SM). To suppress both accidental and physics background in the experiment, a precise measurement of the vertex position, the decay time and the particle momenta is required. The tile detector, which employs scintillation tiles, SiPMs and dedicated readout ASICs, aims at a timing resolution of better than 100 ps.
At the Kirchhoff-Institut für Physik (KIP), Universität Heidelberg, which is responsible for the tile detector research and development, four 16-channel technical prototypes have been assembled and tested at the DESY electron test beam in Hamburg in December 2019. The preliminary results show a single channel timing resolution below 50 ps, which clearly fulfills the requirement of 100 ps.
