Commissioning of the ATLAS Tile Hadronic Calorimeter with cosmic muons, single beams and first collisions

After an extensive period of commissioning with cosmic rays, the ATLAS detector received a brief period of single-proton beam, followed by months of proton-proton collisions from the LHC. The focus of this running period was to commission ATLAS detector for the 2010 collision run during which physics results are expected. In this talk, we will show how early collision data has been used to commission and to calibrate the Tile Hadronic Calorimeter of the ATLAS detector.
