The Mu3e Detector

<!--HTML-->The Mu3e experiment searches for the lepton flavour violating decay µ→ eee with an ultimate aimed sensitivity of 1 event in 10^16 decays. This goal can only be achieved by reducing the material budget per tracking layer to X/X0 ≈ 0.1%. For this purpose, the vertex detector is based on HV-MAPS thinned to 50 µm. Also, the powering and data transmission is performed by means of kapton-aluminum HDIs, which serve as mechanical support as well. This talk will show the detector concept, focusing on the technical aspects of the pixel tracker and its several challenges.
