ATLAS Tile calorimeter commissioning status and performance

The ATLAS Hadronic Tile calorimeter is the barrel hadronic calorimeter for ATLAS at the LHC/CERN. It is made of iron and scintillating tiles, read-out by WLS fibers and PMTs. It should provide precision measurements of jets and missing transverse energy produced at LHC. In the last two years a large effort of commissioning and integration with the ATLAS detector was carried over. Large amount of calibration data has been collected, including Cosmic muon data, first triggered via specially developed trigger boards on the LVL1 output of the Tile calorimeter and later with the standard ATLAS LVL1 calorimeter trigger. In September 2008, with the first single beams circulating in the LHC events resulting from beam-collimator splashes were also recorded. We will describe the most recent aspects of the commissioning activities, status of the calibrations and provide the detector readiness for pp collisions expected at the end of 2009.
