The construction and performance of the barrel pre-series module 0 of the future ATLAS electromagnetic calorimeter at the LHC is described. The signal reconstruction and performance of ATLAS-like ...electronics has been studied. The signal to noise ratio for muons has been found to be 7.11±0.07. An energy resolution of better than
9.5%
