Wednesday 29 October 2008 Speaker: Andreas Korn (LBNL) Title: The ATLAS Pixel Detector: Overview and Commissioning Abstract: The ATLAS experiment at the Large Hadron Collider uses a Pixel Detector as the innermost part of its tracking detector. The Pixel detector is designed to operate in a harsh radiation environment and cope with the fast 40 MHz bunch crossing frequency. The Pixel detector consists of 1744 modules with an active area of about 1.7 square meters and a total of 80 million pixels. An overview of the project is given and the construction experience illustrated. First commissioning results will be highlighted.
