2010 ATLAS Detector Performance I

During the 2010 LHC run the ATLAS detector recorded 45 $\mathrm{pb^{-1}}$ of proton-proton collision data with 93.6\% data taking efficiency and 9.17$\mathrm{\mu b^{-1}}$ of heavy ion collision data. This poster presents the main performance results for each sub-detector which enabled the excellent ATLAS performance during the past year. Particle identification, alignment, tracking resolution and efficiency results are shown for the Inner Detector and Muon Spectrometer. Results on electromagnetic and jet energy scales are presented for the Liquid Argon and Tile calorimeters. Finally, the LUCID and ZDC luminosity measurements are described.
