Status of the Mu3e Tile detector — •Elizaveta Nazarova, Konrad Briggl, Hans-Christian Schultz-Coulon, Jan Küpperbusch, Erik Steinkamp, and Anna Dunz for the Mu3e collaboration — Kirchhoff Institut für Physik, Universität Heidelberg, Heidelberg, Germany
The future Mu3e experiment at the Paul Scherrer Institute (PSI, Switzerland) will search for the decay µ+ → e+ e+ e− down to a branching ratio sensitivity of 10−16. Observation of such a lepton-flavour violating decay will test the Standard Model, where it is highly suppressed. The first phase of the experiment aims to reach the sensitivity of 2 × 10−15 using the availible at PSI muon beam with rates up to 1 × 108 Hz. In order to suppress possible background and perform the search with the proposed sensitivity, the experiment needs precise tracking and time measurements. The Mu3e tile detector is one the dedicated timing systems, providing precise detection of electrons with the time resolution below 100 ps. The detector consists of plastic scintillator tiles that are read out by silicon photomultipliers (SiPMs), while the analog signals of SiPMs are read by the MuTRiG ASICs.
This talk presents an overview of the current status of the Mu3e tile detector, including the development and production of individual components, as well as quality assurance measurements. The production of the full detector and its subsequent integration into the Mu3e experiment will be discussed.
