Abstract :
The ATLAS experiment at the Large Hadron Collider (LHC) at CERN is currently being assembled to be ready to take first data in 2008. Its muon spectrometer is designed to achieve a momentum resolution of better than 10% up to transverse muon momenta of 1 TeV. The spectrometer consists of one barrel and two endcap superconducting air-core toroid magnets instrumented with three layers of precision drift chambers as tracking detectors and a dedicated trigger system. Detailed studies have been performed with a new approach of the autocalibration, a method to determine the space-to-drift- time relation of the ATLAS MDT chambers, and are presented.
