Abstract	The goals of the ongoing and planned ATLAS muon detector upgrades are to increase the acceptance for precision muon momentum measurement and triggering and to improve the rate capability of the muon chambers in the high-background regions corresponding to the increasing LHC luminosity. Smalldiameter Muon Drift Tube (sMDT) chambers have been developed for these purposes. With half the drift-tube diameter of the current ATLAS Muon Drift Tube (MDT) chambers with 30 mm drift tube diameter and otherwise unchanged operating parameters, the sMDT chambers share all the advantages of the MDTs, but have an about an order of magnitude higher rate capability and can be installed in detector regions where MDT chambers do not fit in. The construction of twelve chambers for the feet regions of the ATLAS detector has been completed for the installation in the winter shutdown 2016/17 of the Large Hadron Collider. The purpose of this upgrade of the ATLAS muon spectrometer is to increase the acceptance for three-point muon track measurement which substantially improves the muon momentum resolution in the regions concerned.
