Query: Commissioning and installation of the new small-Diameter Muon Drift Tube
  (sMDT) detectors for the Phase-I upgrade of the ATLAS Muon Spectrometer   The Monitored Drift Tubes, as a part of the ATLAS muon spectrometer, are
precision drift chambers designed to provide excellent spatial resolution and
high tracking efficiency independent of the track angle. Through the life of
the LHC and ATLAS experiment, this detector has already demonstrated that they
provide precise tracking over large areas. The aim of the ATLAS muon
spectrometer upgrade is to increase the muon trigger efficiency, precise muon
momentum measurement and to improve the rate capability of the muon system in
the high-background regions during the High-Luminosity LHC runs. To meet these
requirements, the proposed solution is based on the small (15 mm) diameter Muon
Drift Tube chamber (sMDT) technology. The new detector provides about an order
of magnitude higher rate capability and allows for the installation of
additional new triplet Resistive Plate Chambers (RPCs) trigger detectors in the
barrel inner layer of the muon system. A pilot project for the barrel inner
layer upgrade is underway during the 2019/21 LHC shutdown. For this reason, the
Max-Planck-Institute for Physics in Munich has built 16 sMDT chambers, each
will cover an area of about 2.5 $m^{2}$. To ensure their proper operation in
the experiment, the sMDT detectors have to pass a set of stringent tests both
at the production site and after their delivery at CERN. After their
installation in the ATLAS muon spectrometer, the muon stations are further
tested and commissioned with cosmic rays. The author will describe the detector
design, the quality assurance and certification path, as well as will present
the experience with the chamber tests, the integration procedure and
installation of the muon stations in the ATLAS experiment.
