Resumen:
The Tile hadronic calorimeter of the ATLAS detector has undergone
extensive testing in the experimental hall since its installation
in late 2005. The readout, control and calibration systems
have been fully operational since 2007 and the detector has successfully
collected data from the LHC single beams in 2008 and first
collisions in 2009. This paper gives an overview of the Tile Calorimeter
performance as measured using random triggers, calibration
data, data from cosmic ray muons and single beam data. The detector
operation status, noise characteristics and performance of
the calibration systems are presented, as well as the validation
of the timing and energy calibration carried out with
minimum ionising cosmic ray muons data. The calibration systems
precision
is well below the design value of 1%. The determination of
the global energy scale was performed with an uncertainty of 4%.
