Installation, commissioning and operation of the tile hadron calorimeter of ATLAS

Within the ATLAS experiment at the pp-collider LHC at CERN, the Tile Hadron Calorimeter is the first subdetector to be assembled, commissioned and operated. The calorimeter has successfully been deployed in the ATLAS cavern. The installation of the services and the routing of connections is in progress. The final certification of the front-end electronics has started, using both a temporary and the final back-end. Cosmic muons are used to test the performance and alignment of the whole calorimeter. In parallel, the integration with other ATLAS systems has started.
