Abstract [en]

The construction of the ATLAS liquid argon electromagnetic calorimeters is about to be completed. The barrel calorimeter and the first end-cap are inserted in their cryostats. The quality control performed during the production has resulted in only a very small fraction of malfunctioning channels (similar to0.1%) and a low constant term in the energy resolution. Several modules of the calorimeter and their corresponding presampler sectors have been tested in electron beams, and their energy resolution has been shown to be within the ATLAS requirements. The local constant term is better than 0.4% for all measured cells and the global constant term which includes the cell-to-cell response variation is less than 0.7%.
