Abstract: The tracking and vertexing performance of the ATLAS detector relies critically on the silicon and gaseous tracking subsystems that form the ATLAS Inner Detector. They have been successfully operated with high performance since Run 1 (2010) at the LHC. Those subsystems have undergone significant upgrades to meet the challenges imposed by the higher pileup and luminosity that are being delivered by the LHC, well beyond its original design goals. Furthermore, the Inner Detector was exposed to a radiation dose higher than 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. The key status and performance metrics of the Pixel Detector and the Semi Conductor Tracker are summarised, and the operational experience and requirements to ensure optimum data quality and data taking efficiency are described.
