Description
The Mu3e experiment will search for the charged lepton flavour violating decay
The Mu3e detector will use four layers of thin Mupix sensors (high voltage monolithic active pixel sensors, HV-MAPS) to track electrons and positrons. A time resolution of O(100ps) will be provided by scintillating tile and fibre detectors, which are coupled to SiPMs and read out by the Mutrig chip. A FPGA-based, triggerless DAQ system will collect data from these detectors, which will then be reconstructed in a GPU filter farm.
With Mupix11 and Mutrig3 the sensor developement for phase 1 has concluded and the collaboration has performed engineering runs with a fist prototype of the inner detector region in order to validate a variety of systems and to identify potential issues. With the experience gained from the engineering runs the collaboration is now in the process of constructing the phase 1 detector.
The talk will present the design of the detecor and readout system and discuss the ongoing activities for Mu3e phase 1.
