Development and simulation of the Mu3e tile detector prototype — •Hannah Klingenmeyer — Kirchhoff-Institut für Physik, Universität Heidelberg
The tile detector is a dedicated timing detector system developed for the Mu3e experiment, which 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 spatial and timing measurements are necessary, resulting in the requirement of a time resolution below 100 ps for the tile detector.
The tile detector, which is currently under development, employs plastic scintillator tiles and silicon photomultipliers read out by dedicated ASICs. In this talk, the status of the first technical prototype will be presented. Measurements of the prototype in two testbeam campaigns, undertaken at DESY in 2018, show a preliminary time resolution of the order of 40 ps, well below the required 100 ps. In addition, the experience gained from the construction of the prototype provides crucial input for the definition and finalisation of the production and assembly procedures, which are needed for the final detector system.
Furthermore, the prototype design has been implemented in a CAD software with built-in simulation options, which are used to simulate the heat flow and cooling capabilities of the detector. This is of particular importance regarding the integration of the tile detector within the full experimental setup, as constraints on the final detector design can first be tested and verified in simulation studies.
