Abstract: To cope with the large amount of data and high event rate expected from the planned High-Luminosity LHC (HL-LHC) upgrade, the monitored drift tube (MDT) readout electronics for the ATLAS muon spectrometer will be upgraded. In addition, the MDT detector will be used at the first-level trigger to improve the muon transverse momentum resolution and reduce the trigger rate. About 100 small-radius MDT chambers have been built to replace the current MDT chambers in the innermost barrel region. A new trigger and readout system will be used. Designs for two frontend ASICs and a data transmission board have been finished and detailed standalone and joint tests have been performed. In this paper, we will present the construction of sMDT chambers and the latest studies of the new trigger and readout system.
