Measurement of the response of the ATLAS liquid argon barrel calorimeter to electrons at the 2004 combined test-beam

• During summer and fall 2004, the response of a full slice of the ATLAS barrel detector to different particles was studied in controlled beam. One module of the ATLAS liquid argon barrel calorimeter identical to the production modules and read out by the final front-end and back-end electronics was used for electromagnetic calorimetry. This paper presents and discusses the electron performance of the LAr barrel calorimeter, including linearity, uniformity, and resolution with different amounts of material upstream the calorimeter and energies ranging from 1 to 250 GeV.
