The LHC instantaneous luminosity of pp collisions has been increased during the operation and reached a maximal value of 2.2 × 10 34 cm −2 s −1 in 2017, more than twice of LHC design value (1.0 × 10 34 cm −2 s −1 ). Even with such high luminosity, the Inner Detector took physics data with high efficiency, improving the data-taking system and optimizing the operation settings. The Inner Detector was exposed to a radiation dose higher than what has ever been experienced in any other detectors in high energy physics experiments. Effects of radiation damage on silicon sensors and front-end ASICs were intensively studied. In this paper, the operational experience of the Inner Detector in the ATLAS experiment as well as its performance after high radiation dose are described.

The ATLAS Pixel Detector is the innermost part of the ATLAS Detector at the Large Hadron Collider (LHC) at CERN. It is crucial for tracking and vertexing of charged particles originating from primary or secondary vertices and hence allows track reconstruction and particle tagging, utilised in the many analyses performed on ATLAS data. The LHC has provided an excellent amount of data, leading to challenging conditions for the various subdetectors, which have to cope with an increased data rate and increased radiation damage. In this report, the operational conditions under those circumstances for the ATLAS Pixel Detector are discussed, followed by a brief discussion of some of the effects of radiation damage on the current detector. The challenges for the future, as well as the actions needed to ensure a stable operation, in the upcoming periods of data taking, are outlined.
