Muon tracks are reconstructed with 97% efficiency and a momentum resolution between 3% and 4% for 10 GeV< pT <500 GeV and better than 10% for transverse momenta up to 1 TeV. In this note, the performance of a perfectly calibrated and aligned muon spectrometer will be reviewed and the impact of deteriorations of the magnetic field, the calibration and misalignment of the muon chambers on the performance will be discussed. The main part of the note describes how the performance of the muon spectrometer can be determined using dimuon decays of Z bosons and JPsi mesons</Abstract> Wed, 31 Dec 2008 23:00:00 GMT http://hdl.handle.net/2307/524 2008-12-31T23:00:00Z http://hdl.handle.net/2307/367 <Title>Study of the ATLAS MDT spectrometer using high energy CERN combined test beam data</Title> <Authors>Adorisio, C.; Aielli, G.; Alexopoulos, Th.; Alviggi, M.; Amelung, C.; Anastopoulos, Ch.; Avolio, G.; Avramidou, R.; Bachas, K.; Bagnaia, P.; Ball, R.; Barisonzi, M.; Baroncelli, Antonio; Barone, M.; Bauer, F.; Bellomo, M.; Benhammou, Y.; Bensinger, J.; Beretta, M.; Bianchi, Riccardo Maria; Bianco, M.; Bini, C.; Bobbink, G.; Borisov, A.; Boterenbrood, H.; Boyko, I.; Branchini, Paolo; Brambilla, E.; Brandenburg, G.; Bratzler, U.; Bressler, S.; Brouwer, G.; Cambiaghi, M.; Canale, V.; Caprio, M.; Cardarelli, R.; Cerutti, F.; Chapman, J.

Section A</Is part of> <Volume>598</Volume> <Pages>400-415</Pages> <Abstract>In 2004, a combined system test was performed in the H8 beam line at the CERN SPS with a setup reproducing the geometry of sectors of the ATLAS Muon Spectrometer, formed by three stations of Monitored DriftTubes (MDT). The full ATLAS analysis chain was used to obtain the results presented in this paper. The basic design performances of the Muon Spectrometer were verified. The stability of MDT calibration constants, the alignment system using optical devices and high energy tracks, as well as the intrinsic sagitta resolution of the Muon Spectrometer were studied and found to agree with expectations. The reconstruction of muon tracks using the combined information from both the Inner Detector and the Muon Spectrometer are also presented.</Abstract> Sat, 10 Jan 2009 23:00:00 GMT http://hdl.handle.net/2307/367 2009-01-10T23:00:00Z
