ATLAS Pixel Detector: Analysis of test beam data Magdalena Bazalova

at CERN (European Center for Particle Physics) will use silicon pixel detectors for the three innermost layers of the semiconductor tracker. Their aim is to provide precise posi-tion of particles passing through the detector. A number of test has been performed and a lot of data have been analyzed. Studies of behavior of irradiated and non-irradiated detectors were required; charge collection eciency, spatial resolution, depletion depth, and Lorentz angle measurements had to be dealt with. Data acquired in a high luminosity beam have been analyzed, as well. The analysis of test beam data is the main goal of the paper. Key words: ATLAS Pixel detector, test beam analysis, spatial resolution, depletion depth
