The performance of the ATLAS Inner Detector alignment has been studied using pp collision data at √ s = 13 TeV collected by the ATLAS experiment during Run 2 (2015-2018) of the Large Hadron Collider (LHC). The goal of the detector alignment is to determine the detector geometry as accurately as possible and correct for time-dependent movements. The Inner Detector alignment is based on the minimization of track-hit residuals in a sequence of hierarchical levels, from global mechanical assemblydoi:10.22323/1.276.0196 fatcat:riextprm2nc5tfxb2zz2r53ezi
