Resumen:
The ATLAS detector at the Large Hadron Collider has collected several
hundred million cosmic ray events during 2008 and 2009. These data were
used to commission the Muon Spectrometer and to study the performance
of the trigger and tracking chambers, their alignment, the detector
control system, the data acquisition and the analysis programs. We
present the performance in the relevant parameters that determine the
quality of the muon measurement. We discuss the single element
efficiency, resolution and noise rates, the calibration method of the
detector response and of the alignment system, the track reconstruction
efficiency and the momentum measurement. The results show that the
detector is close to the design performance and that the Muon
Spectrometer is ready to detect muons produced in high energy
protonproton collisions.
