Tests of the Mu3e DAQ in the Cosmic run 2022 — •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.
A prototype of the detector was operated in summer 2022 in the first Mu3e cosmic run with the intent to test and validate a variety of systems. The operated prototype included two cylindrical layers of pixel sensors, a scintillating fibre module and a vertical slice of the final data acquisition (DAQ) system. The talk will focus on the commissioning and validation of the DAQ in this run.
