Data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are used to reconstruct millions of secondary vertices from these nuclear interactions. Precise positions of the beam pipe and the inner tracking system elements, such as the pixel detector support tube, and barrel pixel detector inner shield and support rails, are determined using these vertices. These measurements are important for detector simulations, detector upgrades, and to identify any changes in the positions of inactive elements. ? 2018 CERN for the benefit of the CMS collaboration.Pixels; Radiation detectors; Readout systems; Tellurium compounds; Tracking (position); Detector simulations; Inner tracking system; Nuclear interaction; Pixel detector; Precise position; Precision measurement; Proton proton collisions; Secondary vertices; Nuclear reactions[SDGs]SDG7journal article10.1088/1748-0221/13/10/P100342-s2.0-85056089778
