ATLAS tile calorimeter data quality assessment and performance with calibration, cosmic and first beam data

The commissioning of the barrel hadronic calorimeter (Tile) of the ATLAS detector at the Large Hadron Collider (LHC) has been the focus of an extensive project over the last several years. Work with Tile has resulted in a fully operational detector before the first LHC beam test on 10 September 2008. A set of tools has been developed spanning from the hardware and software systems of the detector and online monitoring to the offline reconstruction. This set of tools constitutes the final Tile data quality system and is highly integrated with all ATLAS online and offline frameworks. ew of the final data quality system of the Tile hadronic calorimeter will be presented together with selected results on hardware reliability. This will be followed by the detector performance checks performed on cosmic data and on the first LHC beam data taken on 10 September 2008.
