The ATLAS detector is a multi-purpose experiment located at one of the collision points the LHC, at CERN. The detector is complete and acquiring data since June 2008. The commissioning of the calorimeter system has been possible since then, in particular through the study of the "missing transverse energy" variable. This variable is essential for precision measurements of the Standard Model, and for the search of New Physics ; it was then tested in situ for the first time. The detector was ready for the first LHC collisions at the end of 2009, and showed good performances, in particular when created by minimum bias events. With the collision data, it was also possible to study the electron performances, in particular the identification vari...
