abstract : The ATLAS liquid argon calorimeter has been operating continuously since August 2006. At
this time, only part of the calorimeter was readout, but since the beginning of 2008, all calorimeter cells
have been connected to the ATLAS readout system in preparation for LHC collisions. This paper gives an
overview of the liquid argon calorimeter performance measured in situ with random triggers, calibration
data, cosmic muons, and LHC beam splash events. Results on the detector operation, timing performance,
electronics noise, and gain stability are presented. High energy deposits from radiative cosmic muons and
beam splash events allow to check the intrinsic constant term of the energy resolution. The uniformity of
the electromagnetic barrel calorimeter response along η (averaged over φ) is measured at the percent level
using minimum ionizing cosmic muons. Finally, studies of electromagnetic showers from radiative muons
have been used to cross-check the Monte Carlo simulation. The performance results obtained using the
ATLAS readout, data acquisition, and reconstruction software indicate that the liquid argon calorimeter
is well-prepared for collisions at the dawn of the LHC era.
