Overview and status of the ATLAS pixel detector

The silicon pixel detector for the ATLAS experiment has been completed and installed. The number of dead channels after the assembly is 0.3%. Before the final assembly, a system test, including all services and DAQ system, was performed on one endcap corresponding to 8% of the detector. This system was used for data taking with cosmic rays, showing an efficiency greater than 99% and an almost noiseless opertion.
