Performance of the ATLAS Tile Calorimeter in pp collisions at the LHC

The Tile Calorimeter is the central section of the ATLAS hadronic calorimeter at the Large Hadron Collider. This detector is instrumented for the measurements of hadrons, jets, tau leptons and missing transverse energy. The data quality procedures used during the LHC data-taking and the evolution of the detector status during the LHC Run1 are presented. The energy and the time reconstruction performance of the digitized signals is summarized and the calorimeter response to hadrons is investigated with collision data.
