Overview and status of the ATLAS Pixel detector

The ATLAS experiment, currently under construction at the large hadron collider (LHC) at CERN (Geneva, Switzerland), will use a silicon Pixel detector as the innermost part of its semiconductor tracker, providing three spacial measurements for tracks produced in high-energy pp collisions. The detector is designed to operate at a 40 MHz bunch crossing frequency, a high-particle flux density and an extreme radiation environment at LHC. The main characteristics of the project are illustrated together with the status of production and recent experimental results.
