Description
The ATLAS experiment at the Large Hadron Collider (LHC) at CERN is
currently being assembled to be ready to take first data in fall 2007. Its
muon spectrometer is designed to achieve a momentum resolution of better
than 10% at pμ = 1 TeV. The spectrometer consists of one barrel and two
endcap superconducting air-core toroid magnets and is instrumented with
three layers of Monitored Drift Tube chambers (Cathode Strip Chambers in
the extreme forward region) as precision detectors. Resistive Plate Chambers
in the barrel and Thin Gap Chambers in the endcap regions form a dedicated
trigger system. We report on our experience with the commissioning and
installation of the precision and trigger chambers. First results of the cosmic
ray test of the barrel muon spectrometer with and without magnetic field
are presented, including results of the calibration of the MDT chambers and
the spectrometer alignment.
