Argonne has contributed centrally to all phases of the ATLAS Tile Calorimeter. Design, prototyping, and fabrication of modules and electronics were carried out in the United States in close collaboration with the University of Chicago, University of Illinois, Michigan State University, and the University of Texas at Arlington. Bob Stanek from Argonne was the project leader for the Tile Calorimeter System from 2005 until 2009. The modules for Extended Barrel A (EBA), one of three barrel assemblies that comprise the Tile Calorimeter, were assembled and tested at Argonne. In the picture above, EBA is shown in the ATLAS cavern at the moment of completion of its assembly from 64 separate modules in May 2006. This completed the mechanical installation of the calorimeter (the barrel was installed in December of 2004 and EBC in February of 2006). The group is now working on calorimeter commissioning, software development and validation, and optimization of the use of the calorimeter signals to reconstruct a measure jets.

Currently the group is involved in TileCal operation and performance studies, monitoring low-voltage power supplies (see Low-Voltage Power Supplies monitoring) , design and fabrication of such power supplies, HV distribution boards for photomultipliers (HV-Opto), signal reconstruction, and QIE development for the Tile readout.
