摘要：

The ATLAS liquid argon calorimeter system is an electromagnetic barrel calorimeter and two electromagnetic, hadronic and forward, endcap calorimeters. This system has finished its construction. It is now in the integration and commissioning phase at CERN. The barrel electromagnetic calorimeter has performed its first complete cool down test. The two endcap calorimeters which contain, in each cryostat, an electromagnetic wheel, two hadronic wheels and three forward wheels, are finalized and prepared for cold tests. A complete status on the construction and integration phases as well as the on going commissioning is presented including quality check results (mechanics and connectivity). Several modules of these calorimeters were beam tested in stand-alone mode as well as in combined mode with electrons, photons and pions of various energies. A selection of the results is presented including energy and position resolution, response uniformity, time measurements, pion and muon responses, comparison to simulations... A status of expected general performances is given.
