“…More specifically, a highly granular electromagnetic (EM) calorimeter with accordion-shaped electrodes and lead absorbers covers the pseudo rapidity range | | < 3.2, and contains a barrel part (EMB [3], | | < 1.475) and an end cap part (EMEC [4], 1.375 < | | < 3.2). For | | < 1.8, a pre sampler (PS [4,5]), consisting of an active LAr layer and installed directly in front of the EM calorimeter, provides a measurement of the energy lost upstream. Located behind the EMEC is a copper-liquid argon hadronic end cap calorimeter (HEC [6], 1.5 < | | < 3.2), and a copper/tungsten-liquid argon forward calorimeter (FCal [7]) covers the region closest to the beam at 3.1 < | | <4.9.…”

The ATLAS calorimeters provide precision measurements of electrons, photons, jets and missing transverse energy produced in the LHC proton-proton collisions. High granularity liquid-argon electromagnetic and hadronic sampling calorimeters are used. An iron-scintillator hadronic calorimeter surrounds the liquid-argon detectors. Results assessing the calorimeter performance obtained using cosmic ray muons are presented. The non-uniformity of the barrel electromagnetic calorimeter response is consistent at the percent level with the simulated response. The response uniformity of the hadronic calorimeter layers is at the level of 4%. The determination of the global energy scale was performed in the hadronic calorimeter with an uncertainty of ±4%.

The ionization signals in the liquid argon of the ATLAS electromagnetic calorimeter are studied in detail using cosmic muons. In particular, the drift time of the ionization electrons is measured and used to assess the intrinsic uniformity of the calorimeter gaps and estimate its impact on the constant term of the energy resolution. The drift times of electrons in the cells of the second layer of the calorimeter are uniform at the level of 1.3% in the barrel and 2.8% in the endcaps. This leads to an estimated contribution to the constant term of (0.29 +0.05 −0.04
