Data Flow in the Mu3e DAQ

The Mu3e experiment at the Paul Scherrer Institute (PSI) searches for charged lepton flavour violating decay $\mu^+ \rightarrow e^+ e^-$. aims an ultimate sensitivity of one in $10^{16}$ $\mu$ decays. first phase experiment, currently under construction, will reach a branching ratio $2\cdot10^{-15}$ by observing $10^{8}$ decays per second over year data taking. highly granular detector based on thin high-voltage monolithic active pixel sensors (HV-MAPS) and scintillating timing detectors produce about 100 GB/s these particle rates. Field Programmable Gate Array Data Acquisition System (DAQ) read out different parts. trigger-less readout system is used to sort, time align analyze while running. A farm PCs equipped with powerful graphics processing units (GPUs) perform event reconstruction reduction. paper presents ongoing integration sub into DAQ, especially focusing aligning flow inside FPGAs filter farm. It also show DAQ Integration Runs performed spring 2021 2022.
