Performance of the ATLAS Tile Calorimeter

The Tile Calorimeter is the central section of the ATLAS hadronic calorimeter. It is a key detector for the measurement of hadrons, jets, tau leptons and missing transverse energy. Because of its very good signal to noise ratio it is also useful for the identification and reconstruction of muons. The calibration and performance of the calorimeter have been established through test beam measurements, cosmic ray muons and the large sample of $pp$ collisions. Results on the calorimeter performance are presented, including the absolute energy scale, time resolution, and associated stabilities.
