The HL-LHC project aims at allowing to increase the collisions in the Large Hadron Collider by a factor ten in the decade 2025 - 2035. One essential element are the superconducting magnets around the interaction region points, where large aperture magnets will be installed to allow to further reduce the beam size in the interaction point.

Summary of Test Results of MQXFS1—The First Short Model 150 mm Aperture Nb$_3$Sn Quadrupole for the High-Luminosity LHC Upgrade
/ Stoynev, S (Fermilab) ; Ambrosio, G (Fermilab) ; Anerella, M (Brookhaven) ; Bossert, R (Fermilab) ; Cavanna, E (CERN) ; Cheng, D ; Dietderich, D (LBNL, Berkeley) ; DiMarco, J (Fermilab) ; Felice, H (Saclay) ; Ferracin, P (CERN) et al.
The development of $Nb_3Sn$ quadrupole magnets for the High-Luminosity LHC upgrade is a joint venture between the US LHC Accelerator Research Program (LARP)* and CERN with the goal of fabricating large aperture quadrupoles for the LHC in-teraction regions (IR). The inner triplet (low-β) NbTi quadrupoles in the IR will be replaced by the stronger Nb$_{3}$Sn magnets boosting the LHC program of having 10-fold increase in integrated luminos-ity after the foreseen upgrades.

Applied metrology in the production of superconducting model magnets for particle accelerators
/ Ferradas Troitino, Jose (CERN) ; Bestmann, Patrick (CERN) ; Bourcey, Nicolas (CERN) ; Carlon Zurita, Alejandro (CERN) ; Cavanna, Eugenio (ASG Supercond., Genova) ; Ferracin, Paolo (CERN) ; Ferradas Troitino, Salvador (CERN) ; Holik, Eddie Frank (Fermilab) ; Izquierdo Bermudez, Susana (CERN) ; Lackner, Friedrich (CERN) et al.
The production of superconducting magnets for particle accelerators involves high precision assemblies and tight tolerances, in order to achieve the requirements for their appropriate performance. It is therefore essential to have a strict control and traceability over the geometry of each component of the system, and also to be able to compensate possible inherent deviations coming from the production process..
