Abstract

The construction of the ATLAS liquid argon electromagnetic calorimeter has been completed and commissioning is in progress to prepare the cryostats for lowering into the ATLAS pit. After a brief description of the detector, its construction and readout electronics, this paper summarizes results of quality checks (electrical, connectivity) carried out during the integration of the calorimeter wheels into the cryostats. We present also selected results of its performance, such as linearity, energy resolution, timing resolution, uniformity of the energy response, obtained in beam tests with several series modules.
