Description
The ATLAS liquid argon (LAr) calorimeter system consists of an
electromagnetic barrel calorimeter and two endcaps with electromagnetic,
hadronic and forward calorimeters. The liquid argon sampling technique,
with an accordion geometry was chosen for the barrel electromagnetic
calorimeter (EMB) and adapted to the endcap (EMEC). The hadronic endcap
calorimeter (HEC) is using a copper-liquid argon sampling technique with flat
plate geometry and is subdivided into two wheels in depth per end-cap.
Finally, the forward calorimeter (FCAL) is composed of three modules
featuring cylindrical electrodes with thin liquid argon gaps.
