Description
The Mu3e experiment aims to find or exclude the lepton flavor violating decay $\mu^+ \rightarrow e^+e^-e^+$ with a sensitivity of one in 10$^{16}$ muon decays. The first phase of the experiment is currently under construction at the Paul Scherrer Institute (PSI, Switzerland), where beams with up to 10$^8$ muons per second are available. The detector will consist of an ultra-thin pixel tracker made from high-voltage monolithic active pixel sensors (HV-MAPS), complemented by scintillating tiles and fibres for precise timing measurements. The experiment produces about 80 GBit/s of zero-suppressed data which are transported to a filter farm using a network of FPGAs and fast optical links. On the filter farm, tracks and three-particle vertices are reconstructed using highly parallel algorithms running on graphics processing units, leading to a reduction of the data to 100 Mbyte/s for mass storage and offline analysis. The talk introduces the system design and reports on progress in building and testing the hardware, firmware and software for this data acquisition system.
