Noise dependence with pile-up in the ATLAS Tile Calorimeter

Detalhes bibliográficos
Resumo:The Tile Calorimeter, TileCal, is the central hadronic calorimeter of the ATLAS experiment, positioned betweentheelectromagneticcalorimeterandthemuonchambers.It comprises alternating layers of steel (as absorber material) and plastic (as active material), known as tiles. Between 2009 and 2012, the LHC has performed better than expected producing proton-proton collisions at a very high rate. These conditions are really challenging when dealing with the energy measurements in the calorimeter since not only the energy from an interesting event will be measured but a component coming from other collisions, which are difficult to distinguish from the interesting one, will also be present. This component is referred to as pile-up noise.Studiescarriedouttobetterunderstandhowpile-upaffects calorimeter noise under different circumstances are described.
