Limits to drift chamber performance at LHC luminosities

Muon spectrometers of the Large Hadron Collider experiments such as ATLAS and CMS have to operate at count rates up to 1 kHz/cm 2 . The ATLAS muon spectrometer physics requires a momentum resolution of ∼10% for muons with a transverse momentum of p T =1 TeV/c . This translates into a spatial resolut...

Description
Summary:Muon spectrometers of the Large Hadron Collider experiments such as ATLAS and CMS have to operate at count rates up to 1 kHz/cm 2 . The ATLAS muon spectrometer physics requires a momentum resolution of ∼10% for muons with a transverse momentum of p T =1 TeV/c . This translates into a spatial resolution of σ ̄ =80 μm for a single-tube measurement and a systematic error to the space–time relationship due to changes of the environmental parameters of smaller than δr r.m.s
