An 8-channels read-out front-end for LHC ATLAS Muon-Drift-Tubes detectors is presented (8xAFE). The system is composed by the cascade of the analog signal processing FrontEnd and of the Wilkinson A/D (to perform voltage-to-time conversion for time-over-threshold detection). The sensitivity at the output of the analog signal processing chain is 13.8mV/fC, while the Equivalent-Noise-Charge (ENC) is...
In the ATLAS Muon Spectrometer, Monitored Drift Tube (MDT) chambers and sMDT chambers with half of the tube diameter of the MDTs are used for precision muon track reconstruction. The sMDT chambers are designed for operation at high counting rates due to neutron and gamma background irradiation expected for the HL-LHC and future hadron colliders. The existing MDT read-out electronics uses bipolar signal...
