The ATLAS Liquid Argon Calorimeters : Construction, Integration, Commissionning

The ATLAS liquid argon calorimeter system consists of an electromagnetic barrel calorimeter and two end-caps comprising electromagnetic, hadronic and forward calorimeters.The construction of the full calorimeter system is completed since mid-2004. After construction in the home institutes, the modules have been integrated into wheels, and inserted into their respective cryostats. Results of electrical and mechanical quality checks performed during module construction, integration into wheels, cold test of complete calorimeter systems before and after lowering into the ATLAS cavern are reported. Finally, some results obtained from the first commissionning data are presented.
