ATLAS tile calorimeter data quality assessment with commissioning data

TileCal is the barrel hadronic calorimeter of the ATLAS experiment presently in an advanced state of installation and commissioning at the LHC accelerator. The complexity of the experiment, the number of electronics channels and the high rate of acquired events requires a detailed commissioning of the detector, during the installation phase of the experiment and in the early life of ATLAS, to verify the correct behaviour of the hardware and software systems. This is done through the acquisition, monitoring, reconstruction and validation of calibration signals as well as processing data obtained with cosmic ray muons. To assess the detector status and verify its performance a set of tools has been developed spanning from the hardware detector verification tests and the online monitoring to the offline reconstruction. Tools allowing for a fast and semi-automated analysis of the result have been developed and the system includes web interfaces to allow for remote monitoring and data quality assessment.
