Status of the Mu3e tile detector — •Hannah Klingenmeyer for the Mu3e collaboration — Kirchhoff-Institut für Physik, Universität Heidelberg
The aim of the Mu3e experiment is the search of the lepton-flavour violating decay µ → eee down to a sensitivity of 10−16. It will be operated at the Paul Scherrer Institute (PSI) in Switzerland and consists of dedicated tracking and timing detectors, which will provide precise spatial and time measurements in order to suppress any background mimicking the signal decay.
One of the timing systems is the Mu3e tile detector, which allows precise timing of individual electrons with a resolution below 100 ps. It uses plastic scintillator tiles and silicon photomultipliers that are read out by a custom-designed ASIC, and is currently in the pre-production phase. This talk will give an overview of the current status and development of the tile detector, as well as of the performance of individual detector components. The tile matrix production and quality assurance measurements will be discussed along with advancements in the readout electronics, the cooling system, and the integration into the full experiment. Furthermore, an outlook on the full detector production will be given.
