    "abstract": "Monitored Drift Tube (MDT) chambers will constitute the large majority of\nprecision detectors in the Muon Spectrometer of the ATLAS experiment at the\nLarge Hadron Collider at CERN. For commissioning and calibration of MDT\nchambers, a Cosmic Ray Measurement Facility is in operation at Munich\nUniversity. The objectives of this facility are to test the chambers and\non-chamber electronics, to map the positions of the anode wires within the\nchambers with the precision needed for standalone muon momentum measurement in\nATLAS, and to gain experience in the operation of the chambers and on-line\ncalibration procedures.\n  Until the start of muon chamber installation in ATLAS, 88 chambers built at\nthe Max Planck Institute for Physics in Munich have to be commissioned and\ncalibrated. With a data taking period of one day individual wire positions can\nbe measured with an accuracy of 8.3 micrometers in the chamber plane and 27\nmicrometers in the direction perpendicular to that plane.",
