Description
The Mu3e experiment is searching for the lepton flavour violating decay μ+→e+e−e+. In an environment of up to 10^9 muon decays per second the detector needs to provide precise vertex, time and momentum information to suppress both physics and accidental background. The detector consists of cylindrical layers of 50 μm thin High Voltage Monolithic Active Pixel Sensors (HV-MAPS) placed in a 1 T magnetic field, which allow a precise vertex and momentum reconstruction. Additional layers of fast scintillating fibre and tile detectors are providing sub-nanosecond time resolution.
The development of the Mu3e vertex and tracking system are described, showing the R&D progress on the chip technology and module construction.
