The semiconductor tracker (SCT) is one of the tracking systems forcharged particles in the ATLAS detector. It consists of 4088 siliconstrip sensor modules. During Run 2 (2015-2018) the Large Hadron Colliderdelivered an integrated luminosity of 156 fb(-1) to the ATLAS experimentat a centre-of-mass proton-proton collision energy of 13 TeV.
