Calibration and signal reconstruction in the ATLAS Tile Hadronic calorimeter

Abstract : TileCal is the barrel hadronic calorimeter of the ATLAS experiment at LHC/CERN, made of steel and scintillating tiles and read out by optical fibers and photomultiplier tubes. It provides measurements for hadrons, jets and missing transverse energy. The TileCal calibration procedures rely on the performance of dedicated calibration systems: - calibration of the full signal read-out path with movable radioactive 137Cs gamma source; - monitoring of the Photomultiplier tube gains with the laser system; - calibration of the front-end electronic gains with the charge injection system. In this talk we will describe the energy and time calibration procedures used in TileCal to establish the reference detector response and synchronization. We will also discuss the calibration systems performance and the corresponding uncertainties to the energy and timing measurements.
