Performance of the ATLAS Precision Muon Chambers under LHC Operating Conditions
/ Deile, M. (Munich, Max Planck Inst.) ; Dietl, H (Munich, Max Planck Inst.) ; Dubbert, J (Munich U.) ; Horvat, S (Munich, Max Planck Inst.) ; Kortner, O (Munich, Max Planck Inst.) ; Kroha, H (Munich, Max Planck Inst.) ; Manz, A (Munich, Max Planck Inst.) ; Mohrdieck, S (Munich, Max Planck Inst.) ; Rauscher, F (Munich U.) ; Richter, Robert (Munich, Max Planck Inst.) et al.
For the muon spectrometer of the ATLAS detector at the large hadron collider (LHC), large drift chambers consisting of 6 to 8 layers of pressurized drift tubes are used for precision tracking covering an active area of 5000 m2 in the toroidal ?eld of superconducting air core magnets. The chambers have to provide a spatial resolution of 41 microns with Ar:CO2 (93:7) gas mixture at an absolute pressure of 3 bar and gas gain of 2?104. [...]

(CERN ; Munich U. ; Munich, Max Planck Inst.) et al.
The resolution and efficiency of a precision drift-tube chamber for the ATLAS muon spectrometer with final read-out electronics was tested at the Gamma Irradiation Facility at CERN in a 100 GeV muon beam and at photon irradiation rates of up to 990 Hz/square cm which corresponds to twice the highest background rate expected in ATLAS. A silicon strip detector telescope was used as external reference in the beam. [...]

Development of Fast High-Resolution Muon Drift-Tube Detectors for High Counting Rates

Pressurized drift-tube chambers are e?cient detectors for high-precision tracking over large areas. The Monitored Drift-Tube (MDT) chambers of the muon spectrometer of the ATLAS detector at the Large Hadron Collider (LHC) reach a spatial resolution of 35 micons and almost 100% tracking e?ciency with 6 layers of 30 mm diameter drift tubes operated with Ar:CO2 (93:7) gas mixture at 3 bar and a gas gain of 20000.

Upgrade of the ATLAS Muon Trigger for the SLHC
/ Dubbert, Jorg (Munich, Max Planck Inst.) ; Horvat, Sandra (Munich, Max Planck Inst.) ; Kortner, Oliver (Munich, Max Planck Inst.) ; Kroha, Hubert (Munich, Max Planck Inst.) ; Richter, Robert (Munich, Max Planck Inst.)
The outer shell of the ATLAS experiment at the LHC consists of a system of toroidal air-core magnets in order to allow for the precise measurement of the transverse momentum p$_T$ of muons, which in many physics channels are a signature of interesting physics processes. For the precise determination of the muon momentum Monitored Drift Tube chambers (MDT) with high position accuracy are used, while for the fast identification of muon tracks chambers with high time resolution are used, able to select muons above a predefined p$_T$ threshold for use in the first Level of the ATLAS triggering system (Level-1 trigger).
