Beschreibungen/Notizen

• The ATLAS muon spectrometer will measure muon tracks along a spectrometer arm of up to 15 m length, embedded in a magnetic field of ∼0.5 T . The precision tracking devices in the muon system will be high-pressure drift tubes (MDTs). To achieve a momentum resolution of ∼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 δ r.m.s. <70 μm . Contributions to a systematic error δ 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.
