Abstract

The ATLAS muon spectrometer will measure muon tracks along a spectrometer arm of up to 15 m length, embedded in a magnetic field of similar to 0.5 T. The precision tracking devices in the muon system will be high-pressure drift tubes (MDTs). To achieve a momentum resolution of similar to 10% for muons with a transverse momentum of p(T) = 1 TeV/c, the systematic error to the space-time relationship has to be smaller than delta (r.m.s.) < 70 <mu>m. Contributions to a systematic error delta (r.m.s.) and its impact on the muon-momentum resolution are discussed. LHC physics require excellent knowledge of the absolute momentum scale. We show a calibration method which will achieve an accuracy at the 10(-4) level, (C) 2001 Elsevier Science B,V. All rights reserved.
