Overview and Status of the ATLAS Pixel Detector

The ATLAS experiment at the Large Hadron Collider will use a Pixel Detector as the innermost part of its tracking detector. The Pixel detector is designed to operate with a 40 MHz bunch crossing frequency, a high particle flux density and an unprecedented extreme radiation environment. The Pixel detector will consist of 1744 modules, arranged in three layers in the barrel part and three disks at each of the two forward regions. The total active area will cover about 1.7 m2 with over 80 million pixel cells. An overview of the project is given and the construction experience illustrated.
