Description
The Tile Calorimeter (TileCal) is the central hadronic calorimeter of
the ATLAS experiment at the LHC. It provides precise measurements of
hadrons, jets, taus and missing transverse energy. The monitoring and
calibration of the calorimeter response at each stage of the signal
development is allowed by a movable Cs^{137} radioactive source, a
laser calibration system and a charge injection system. Moreover,
during the LHC data taking, an integrator based readout provides the
signals coming from inelastic proton-proton collisions at low momentum
transfer (minimum bias currents) and allows to monitor the
instantaneous ATLAS luminosity as well as the response of calorimeter
cells. Minimum bias currents have been used to detect and quantify the
effect of TileCal scintillators irradiation using the data taken
in 2012 and 2015, and that corresponds to about 21 fb^{-1} and 4 fb^{-1} of integrated luminosity.
FInally, the response variation for an irradiated cells has been studied combining the information from three calibration systems (cesium, laser and minimum bias).
The result of the irradiation on the Tile calorimeter response will be reported.
