Status of the front-end electronics for the Phase-II upgrade of the ATLAS Monitored Drift Tube detector

The ATLAS monitored drift tube (MDT) chambers are the main component of the precision tracking system in the ATLAS muon spectrometer. The MDT system is capable of measuring the sagitta of muon tracks to an accuracy of 60 μm, which corresponds to a momentum accuracy of about 10% at pT=1 TeV. ATLAS plans to use the MDT detector in the first stage of the trigger system in the Phase 2 upgrade for the High-Luminosity LHC to improve the muon transverse momentum resolution and to reduce the trigger rate. A new trigger and readout system has been proposed. Front-end electronics, which include two application-specific integrated circuits (ASICs) and a prototype of a data transmission board, have been produced and tested. I will present the current production and test status of the MDT front-end electronics.
