Operational experience and performance with the ATLAS Pixel Detector

The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector. It has undergone significant hardware and software upgrades to meet the challenges imposed by the higher collision energy, pile-up, and luminosity that are being delivered by the Large Hadron Collider. With the LHC recently surpassing instantaneous luminosities of 1.3×10$^{34}$ cm$^{-2}$s$^{-1}$ , the key status and performance metrics of the ATLAS Pixel Detector are summarized. The operational experience and requirements to ensure optimum data quality and data taking efficiency are described, with special emphasis to radiation damage experience.
