Description
The Mu3e experiment at the Paul Scherrer Institute searches for the lepton flavour violating decay $\mu^+ \rightarrow e^+ e^+ e^-$.
The experiment aims for an ultimate sensitivity of one in $10^{16}$ $\mu$ decays.
The first phase of the experiment, currently under construction, will reach a branching ratio sensitivity of $2\cdot10^{-15}$ by observing $10^{8}$ $\mu$ decays per second over a year of data taking.
The highly granular detector based on thin high-voltage monolithic active pixel sensors (HV-MAPS) and scintillating timing detectors will produce about 100 GB/s of data at these rates.
The Field Programmable Gate Array based Mu3e Data Acquisition System will read out this data from the detector and identify interesting events using a farm of graphics processing units.
The poster presents the status of the DAQ and first results from the 2021 integration run, which for the first time operated a slice of the Mu3e detector with the muon beam at PSI.
