Status and Challenges in the MQXFB Nb3Sn Quadrupoles for the HL-LHC / LARP Collaboration
The inner triplet (or low-$\beta$) quadrupole magnets are among the components to be upgraded in LHC interaction regions for the HL-LHC project. The new quadrupole magnets, called MQXF, are based on Nb3Sn superconducting magnet technology, with a conductor peak field of 11.3 T. [...]

Conceptual Design of BOND: A 14 T Dipole for FCC-Hh / Perez, Juan Carlos (CERN) ; Bellini, Gloria (CERN) ; Mora, Elena Fernandez (CERN) ; Ferradas Troitino, Jose (CERN) ; Haziot, Ariel (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Todesco, Ezio (CERN)
High Field Nb$_{3}$Sn superconducting magnets are a core technology to increase the collision energy of particle accelerators beyond that of the Large Hadron Collider (LHC). In the framework of the conceptual design of a Future Circular Collider (FCC), or an energy upgrade of the LHC, different magnet layouts are being considered within the so-called High Field Magnet program.

First CERN Cold Masses for the HL-LHC Interaction Regions / Prin, Herve (CERN) ; Axensalva, Jerome (CERN) ; Bampton, Tavis (CERN) ; Bourcey, Nicolas (CERN) ; Devred, Arnaud (CERN) ; Duarte Ramos, Delio Luis (CERN) ; Ferradas Troitino, Jose (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Milanese, Attilio (CERN) ; Pentella, Mariano (CERN) et al.
In the framework of the HL-LHC project, CERN has the responsibility to develop, qualify and assemble three different types of cold masses, namely Q2 (final focus quadrupole in the triplet), CP (corrector package) and D2 (separation dipole). In this paper, we describe the various designs, which incorporate several novel features. [...]

Investigating the effect of rolling deformation on the electro-mechanical limits of Nb$_{3}$Sn wires produced by RRP$^{®}$ and PIT technologies / Bagni, T (U. Geneva (main) ; Uppsala U.) ; Calzolaio, C (PSI, Villigen) ; Bovone, G (U. Geneva (main)) ; Ferradas-Troitino, J (CERN) ; Barth, C (CERN) ; Ballarino, A (CERN) ; Senatore, C (U. Geneva (main))
Future high-field magnets for particle accelerators hinge on the crucial development of advanced Nb$_{3}$Sn wires engineered to withstand the large stresses generated during magnet assembly and operation. The superconducting properties of Nb$_{3}$Sn enable the design of compact accelerator-quality magnets above 10 T, but at the same time the brittleness and strain sensitivity of the material impose careful consideration of the mechanical limits.

Towards MQXFB Series Coils / Lusa, Nicholas (CERN) ; Devred, Arnaud (CERN) ; Ferradas Troitino, José (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Milanese, Attilio (CERN) ; Quassolo, Penelope Matilde (CERN) ; Straarup, Simon (CERN) ; Todesco, Ezio (CERN)
The cold powering test of the first two MQXFB prototype quadrupoles, the Nb$_3$Sn inner triplet magnets to be installed in the HL-LHC, has found performance limitations. This prompted putting on hold the coil fabrication, to review in depth the full manufacturing process, while in parallel performing destructive inspections on selected coils. [...]

Degradation of I $_{c}$ due to residual stress in high-performance Nb$_{3}$Sn wires submitted to compressive transverse force / Senatore, C (U. Geneva (main) ; Geneva U.) ; Bagni, T (U. Geneva (main)) ; Ferradas-Troitino, J (U. Geneva (main) ; CERN) ; Bordini, B (CERN) ; Ballarino, A (CERN)
Future particle colliders in search for new physics at the energy frontier require the development of accelerator magnets capable of producing fields well beyond those attainable with Nb-Ti. As the next generation of high-field accelerator magnets is presently planned to be based on Nb$_{3}$Sn, it becomes crucial to establish precisely the mechanical limits at which this brittle and strain sensitive superconductor can operate safely.
