Synchronisation of the Mu3e DAQ System — •Martin Müller for the Mu3e collaboration — Institute for Nuclear Physics, JGU Mainz
The Mu3e experiment will search for the lepton flavour violating decay µ+ → e+ e− e+ and is aiming for a sensitivity of one in 1016 muon decays. Since this decay is highly suppressed in the Standard Model to a branching ratio of below O(10−54), an observation would be a clear sign for new physics.
In the Mu3e detector, four layers of silicon pixel sensors will be used to track electrons and positrons and a time resolution of O(100 ps) will be provided by scintillating tile and fibre detectors. The overall detector is expected to produce a data rate from 80 Gbit/s (Phase I) to 1 Tbit/s (Phase II), which will be processed in a three-layer, triggerless DAQ system using FPGAs and a GPU filter farm for online event selection.
The talk will focus on the synchronisation of the different detector parts and the firmware implementation of the clock and reset distribution in the Mu3e DAQ system.
