Finite Element Analysis of the Mechanical Conditions of the Nb$_3$Sn Cable of the 11 T Dipole Magnet During Operation / Löffler, Christian (CERN) ; Daly, Michael (CERN) ; Nilsson, Emelie (CERN) ; Savary, Frederic (CERN)
The development of the 11 T Dipole for the Dispersion Suppressor Collimators (DS11T) for the HiLumi LHC Project at CERN is nearly completed for the RRP conductor route. The DS11T magnet has a cosine theta 60-mm bore design with a removable pole, 56 turns, five wedges, and six coil blocks per quadrant. [...]

Mechanical analysis of the collaring process of the 11 T dipole magnet / Ferracin, Paolo (CERN) ; Bottura, Luca (CERN) ; Bourcey, Nicolas (CERN) ; Daly, Michael (CERN) ; Devred, Arnaud (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Ferradas Troitino, Jose (CERN) ; Ferradas Troitino, Salvador (CERN) ; Grosclaude, Philippe (CERN) ; Guinchard, Michael (CERN) et al.
As part of the Large Hadron Collider (LHC) accelerator upgrades foreseen by the high luminosity-LHC project, the CERN 11 T program is aimed at replacing standard LHC Nb-Ti main dipole magnets, operating with a bore field of 8.3 T, with pairs of shorter Nb$_3$Sn dipole magnets with a bore field of 11 T and the same total integrated field, thus providing space for additional collimators in the dispersion suppressor region. At the time of the submission of this paper, six single-aperture and two double-aperture short models have been fabricated and tested. [...]

Effect of Applied Compressive Stress and Impregnation Material on Internal Strain and Stress State in Nb$_3$Sn Rutherford Cable Stacks / Wolf, Felix (CERN) ; Scheuerlein, Christian (CERN) ; Lorentzon, Marcus (CERN) ; Katzer, Balduin (CERN) ; Hofmann, Michael (Forschungsreaktor Munich) ; Gan, Weimin ; Lackner, Friedrich (CERN) ; Schoerling, Daniel (CERN) ; Tommasini, Davide (CERN) ; Savary, Frederic (CERN) et al.
The Nb3Sn superconductor in accelerator magnets must resist high mechanical stresses. In order to better understand the effect of the coil impregnation system on the stresses exerted on the strain-sensitive Nb3Sn superconductor, we have measured the elastic strain evolution in the conductor constituents under externally applied loads. [...]

3-D thermal-electric finite element model of a Nb$_3$Sn coil during a quench / Ferradas Troitino, Jose (U. Geneva (main) ; CERN) ; Ambrosio, Giorgio (Fermilab) ; Bajas, Hugo (CERN) ; Bordini, Bernardo (CERN) ; Ferracin, Paolo (CERN) ; Fleiter, Jerome (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Gomez, Jose Vicente Lorenzo (Barcelona Supercomputing Ctr.) ; Perez, Juan Carlos (CERN) ; Vallone, Giorgio (LBNL, Berkeley) et al.
High field superconducting magnets for particle accelerators often exhibit premature quenches. Once a normal zone is generated within the conductor, the quench may propagate causing temperature and resistive voltage rise along the coil. [...]

Effect of Epoxy Volume Fraction on the Stiffness of Nb$_3$Sn Rutherford Cable Stacks / Wolf, Felix (CERN) ; Lackner, Friedrich (CERN) ; Hofmann, Michael (Forschungsreaktor Munich) ; Scheuerlein, Christian (CERN) ; Schoerling, Daniel (CERN) ; Tommasini, Davide (CERN)
For the optimization of Nb3Sn superconducting accelerator magnet design and assembly parameters the stress-strain behavior of the coils needs to be known. We have measured the stiffness of Nb3Sn Rutherford cable stacks with different epoxy volume fraction. [...]

Direct measurement of Nb$_{3}$Sn filament loading strain and stress in accelerator magnet coil segments / Scheuerlein, C (CERN) ; Wolf, F (CERN) ; Lorentzon, M (CERN) ; Hofmann, M (Forschungsreaktor Munich)
We have directly measured, for the first time, the Nb3Sn and Cu loading strains and stresses in 11 T dipole coil segments upon compressive loading using neutron diffraction. For this purpose a load frame that enables rotation of the sample load axis with respect to the neutron scattering geometry was installed in the Stress-Spec beamline at the Heinz Maier-Leibnitz FRM II neutron source.

The U.S. High-Luminosity LHC Accelerator Upgrade Project (HL-LHC AUP) team is collaborating with CERN in the design and fabrication of the first 4.5 m long MQXFA magnets, a 150 mm aperture high-field Nb$_3$Sn quadrupole magnet that uses the aluminum shell-based bladder-and-key technology. [...]

Mechanical Comparison of Short Models of Nb$_3$ Sn Low-$\beta$ Quadrupole for the Hi-Lumi LHC / LARP Collaboration
-MQXF is the Nb3Sn Low-β quadrupole magnet that the HL-LHC project is planning to install in the LHC interaction regions in 2026 to increase the LHC integrated luminosity. The magnet will be fabricated in two different lengths: 4.2 m for MQXFA, built in the US by the Accelerator Upgrade Project (AUP), and 7.15 m for MQXFB, fabricated by CERN. [...]

Assembly and Test Results of the RMM1a,b Magnet, a CERN Technology Demonstrator Towards Nb3Sn Ultimate Performance / Gautheron, Emma (CERN) ; Bordini, Bernardo (CERN) ; Campagna, Guillaume (CERN) ; Felice, Hélène (CERN) ; Fleiter, Jerome (CERN) ; Guinchard, Michael (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Mugnier, Sylvain (CERN) ; Perez, Juan Carlos (CERN) ; Petrone, Carlo (CERN) et al.
As part of the High Field Magnet technology development carried out at CERN, demonstrators are under construction to explore the full potential of Nb 3 Sn. The Racetrack Model Magnet (RMM) is one of them, building upon the successful Enhanced Racetrack Model Coil (eRMC) eRMC1a magnet which reached 16.5 T peak field or 16.3 T bore field at 1.9 K. [...]
