On the Production and QA of the Mu3e Tile Detector — •Küpperbusch Jan for the Mu3e collaboration — Kirchhoff-Institut für Physik, Heidelberg, Deutschland
The Mu3e experiment aims to find or exclude the occurrence of the decay µ+ → e+e−e+ with a sensitivity of O(10−15) in phase I and O(10−16) in phase II. In order to achieve this, the Mu3e experiment will be conducted at the Paul-Scherrer-Institute (PSI) utilizing the high rate muon beam (108 Hz in Phase I).
The Scintillating Tile Detector is one of the timing detector systems aiming to perform with a resolution of <100 ps and is located at the two outer stations. It consists of organic scintillators precisely milled into tiles with a surface profile of roughly 5× 5 mm2. The tiles are wrapped in highly-reflective foil, glued to a Silicon Photomultiplier (SiPM) and read out by the MuTRiG, an application-specific integrated circuit (ASIC) which was developed for the Mu3e timing systems. Individual Channels are geometrically grouped onto separate PCB matrices hosting 4× 4 channels, which simplifies production, calibration and quality assurance.
The talk will report on the quality assurance measurements of around 3200 individual channels including bare characterization of the SiPMs, as well as measurements of the finite assembled matrices with scintillator tiles.
