Calibration of the ATLAS Tile Calorimeter: Laser events in the empty bunch crossing.
/ Romano Saez, Silvestre Marino (Laboratoire de Physique Corpusculaire (LPC), Clermont Universite, Universite Blaise Pascal, CNRS/IN2P3, Clermont-Ferrand, France) ; Calvet, Samuel (Laboratoire de Physique Corpusculaire (LPC), Clermont Universite, Universite Blaise Pascal, CNRS/IN2P3, Clermont-Ferrand, France)
/ATLAS Collaboration
The laser system provides a set of calibration constants applied in the energy measure- ments made for the PMTs of the hadronic calorimeter of the ATLAS detector. The object of this study is to determine if the collision runs can be used to perform the calibration. [...]

Energy response uniformity to cosmic muons of the ATLAS Hadronic Tile Calorimeter, with calorimeter-based reconstruction
/ Sousa, M J ; Saraiva, J G ; Filho, L M A ; Maio, A ; Maneira, J ; Ribeiro, N ; Seixas, J M ; Sumida, T
This note presents a study of the Tile Calorimeter (TileCal) energy response uniformity carried out using the energy loss of cosmic ray muons. The muon tracks are reconstructed with the TileMuonFitter (TMF) algorithm, applying the Hough Transform method and using only quantities from and measured by TileCal. [...]
