Summary
The modules of the ATLAS Tile hadronic calorimeter (Tilecal) underwent extensive tests
in the SPS beams at CERN. Studies were carried out with electrons, muons and
hadrons ranging in energy from 10 GeV to 350 GeV.
The Tilecal calibration systems and energy reconstruction algorithms were also
studied in great details, the associated systematics has been evaluated. The
updated calibration scheme led to improved linearity and uniformity of the
response.
Electrons and muons were used to set and understand the EM scale and the
uniformity of the calorimeter. The pion response shows the expected behaviour
with energy. The performance of the real Tile calorimeter modules to
pions in terms of linearity and resolution corresponds well to that of earlier
Tilecal prototype modules, after accounting for the different lengths and
segmentations of the calorimeters.
The experimental results are also compared to several MC simulation samples.
