Mu3e electrical readout chain — •Lars Olivier Sebastian Noehte for the Mu3e collaboration — Physikalisches Institut, Heidelberg
The Mu3e experiment is going to search for the charged lepton-flavour violating decay µ+ → e+ e− e+ with a sensitivity of 1 in 1016 decays in phase 2.
The pixel tracker is based on HV-MAPS and creates an untriggered continuous data stream with a total data rate of approximately 1 Tbit/s.
The tracker is read out via 3060 differential links running at 1.25 Gbit/s.
To minimise multiple Coulomb scattering ultra-thin tracking layers, consisting of monolithic pixel sensors with a thickness of 50 µ m and high density interconnects made out of aluminum and polyimide are used.
The tracking layers are designed to have a total radiation length of about X/X0 = 0.115 % per layer.
This talk focuses on the Mu3e electrical readout chain between the sensor chips and FPGA-frontend boards.
It is going to cover high density interconnects being aluminum polyimide flexprints as well as micro twisted pair cables and high-speed interposer arrays.
Results of the commissioning tests are presented and discussed.
