ATLAS Pixel Detector: Running Experience

The ATLAS Pixel Detector is the innermost tracking device of the ATLAS Experiment. It was successfully commissioned in the year 2008. Calibration measurements have been performed in-situ to set and measure important detector parameters like threshold, charge measurement calibration and timewalk. In combined data taking with the other ATLAS subdetectors by now more than half a million cosmic ray tracks have been collected, which have been used to perform a first alignment and to measure pixel efficiency and noise occupancy. This paper presents results both from the calibration effort in 2008 and from data taking with cosmic rays. A summary of the current detector status is given.
