Description
The Tile Calorimeter (TileCal) is the hadronic calorimeter covering the central
region of the ATLAS experiment at the LHC. This sampling device is made of plastic
scintillating tiles alternated with iron plates and its response is calibrated
to electromagnetic scale by means of several dedicated calibration systems.
The accurate time calibration is important for the energy reconstruction,
non-collision background removal as well as for specific physics analyses.
The initial time calibration with so-called splash events and subsequent
fine-tuning with collision data are presented. The monitoring of the time
calibration with laser system and physics collision data is
discussed as well as the corrections for sudden changes performed still before
the recorded data are processed for physics analyses. Finally, the time
resolution as measured with jets and isolated muons particles is presented.
