Popis: The large hadron collider short straight sections (SSS) are currently being installed in their final position in the accelerator tunnel. For all the SSSs, both those in the regular arcs as well as those in the insertion regions, magnetic axis and geometric measurements are made at different steps of their assembly. These stages range from production in the industry to the cryostating at CERN, as well as during and after cold tests or during installation of the BPM/beam screen assembly. The results of the geometry at the various production stages by means of different procedures and analysis tools are reported and discussed in details in this paper.
