Abstract
The performance of ATLAS SemiConductor Tracker (SCT) in Run-2 at Large Hadron Collider (LHC) has been reviewed during the current long shutdown. The LHC successfully completed its Run-2 operation (2015-2018) with a total integrated delivered luminosity of 156 fb$^{-1}$ at the centre-of-mass $pp$ collision energy of 13 TeV. The LHC high performance provides a good opportunity for physics analysis. The instantaneous luminosity and pileup conditions were far in excess of what the SCT was originally designed to meet. This document will summarise the operational experience and performance of the SCT during Run-2, with a focus on the impact and mitigation of radiation damage effects, which were observed in Run-2.
