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. [...]

Magnetic measurements and analysis of the first 11-T Nb$_3$ Sn 2-in-1 model for HL-LHC / Fiscarelli, Lucio (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Dunkel, Olaf (CERN) ; Russenschuck, Stephan (CERN) ; Savary, Frederic (CERN) ; Willering, Gerard (CERN)
In the framework of the High-Luminosity upgrade of the Large Hadron Collider, the design and development of new magnets, relying on Nb$_{3}$Sn superconducting cables, is progressing. In particular, a double-aperture dipole, with a bore diameter of 60 mm and a central field of 11 T, is required for the replacement of some Nb-Ti dipoles in the dispersion suppressor areas. [...]

Mechanical analysis of the Nb$_3$Sn 11 T dipole short models for the High Luminosity Large Hadron Collider / Izquierdo Bermudez, S (CERN) ; Nilsson, E (CERN) ; Bottura, L (CERN) ; Bourcey, N (CERN) ; Devred, A ; Ferracin, P (CERN) ; Ferradas Troitino, S (CERN) ; Fiscarelli, L (CERN) ; Guinchard, M (CERN) ; Löffler, C (CERN) et al.
For the Large Hadron Collider luminosity upgrade, two of the NbTi 8.3 T main bending dipoles will be replaced by two shorter Nb$_3$Sn 11.2 T dipoles to create space for the installation of collimators in the dispersion suppression region. With the aim to verify the design features, several 2 m long 11 T models have been constructed and tested at CERN. [...]

Field Quality of MBH 11-T Dipoles for HL-LHC and Impact on Beam Dynamic Aperture / Fiscarelli, Lucio (CERN) ; Giovannozzi, Massimo (CERN) ; Hermes, Pascal Dominik (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Russenschuck, Stephan (CERN) ; Savary, Frederic (CERN)
For the high-luminosity upgrade of the Large Hadron Collider (HL-LHC), the development of the 11-T Nb$_{3}$Sn dipole (MBH) is progressing. At present, one double-aperture and five single-aperture short-model magnets have been built and tested. [...]

Optimization of the Electromagnetic Design of the FCC Sextupoles and Octupoles / Louzguiti, Alexandre (CERN) ; Araujo, Douglas Martins (CERN) ; Pracht, Dimitri (CERN) ; Prioli, Marco (CERN) ; Ravaioli, Emmanuele (CERN) ; Schoerling, Daniel (CERN) ; Vallone, Giorgio (CERN)
The future circular collider (FCC) will require 696 double-aperture lattice sextupoles, 9336 single-aperture sextupole corrector magnets, and 480 double-aperture octupoles. The tunnel length and the overall integrated field of the main dipoles have to be kept constant so that the FCC can both reach the specified center of mass collision energy and fit into the Geneva basin.

Characterization of the Mechanical Properties of Nb$_3$Sn Coils / Fernández, José Luis Rudeiros (CERN) ; Perez, Juan Carlos (CERN) ; Ferradas Troitino, Salvador (CERN) ; Guinchard, Michael (CERN) ; Grosclaude, Philippe (CERN) ; Crouvizier, Mickael D (CERN) ; Langeslag, Stefanie (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Savary, Frederic (CERN)
The 11 T magnet and other high-field magnets in the framework of the High-Luminosity Large Hadron Collider project are based on epoxy resin impregnated Nb3Sn coils. This paper presents the development of an experimental measurement setup, and associated methodology for the determination of the mechanical properties in compression of epoxy resin impregnated Nb3Sn coils.

Length Changes of Unconfined Nb$_3$Sn Rutherford Cables During Reaction Heat Treatment / Michels, Matthias (CERN) ; Lackner, Friedrich (CERN) ; Scheuerlein, Christian (CERN) ; Carlon Zurita, Alejandro (CERN) ; Ferradas Troitino, Salvador (CERN) ; Bourcey, Nicolas (CERN) ; Savary, Frederic (CERN) ; Tommasini, Davide (CERN)
In order to predict volume changes of Nb3Sn coils during reaction heat treatment (RHT), coefficients of thermal expansion (CTE) of the involved materials need to be known. While the CTEs of bulk materials are widely available, there is a lack of knowledge about the dimensional changes of the Nb3Sn Rutherford cables. [...]

Quench protection study of a 11 T Nb$_3$Sn model dipole for the High Luminosity LHC / Izquierdo Bermudez, Susana (CERN) ; Mangiarotti, Franco (CERN) ; Willering, Gerard (CERN) ; Bajko, Marta (CERN) ; Bottura, Luca (CERN) ; Ferradas Troitino, Jose (CERN) ; Guinchard, Michael (CERN) ; Savary, Frederic (CERN) ; Vallone, Giorgio (CERN)
The planned upgrade of the Large Hadron Collider collimation system requires the installation of 11 T Nb$_3$Sn dipole magnets in the dispersion suppressor areas. Due to the large stored energy density and the low copper stabilizer section, the quench protection of these magnets is particularly challenging. [...]

Coil manufacturing process of the first 1-m-long Canted–Cosine–Theta (CCT) model magnet at PSI / Montenero, Giuseppe (PSI, Villigen) ; Auchmann, Bernhard (CERN ; PSI, Villigen) ; Arbelaez, Diego (LBNL, Berkeley) ; Brouwer, Lucas (LBNL, Berkeley) ; Caspi, Shlomo (LBNL, Berkeley) ; Felder, Roland (PSI, Villigen) ; Lackner, Friedrich (CERN) ; Sanfilippo, Stephane (PSI, Villigen) ; Sidorov, Serguei (PSI, Villigen) ; Smekens, David (CERN) et al.
At the Paul Scherrer Institute (PSI), the Canted-Cosine-Theta (CCT) magnet program aims at demonstrating that CCT technology is a viable candidate for the development of 16-T dipole magnets, required for future circular colliders. The first step in this direction is the implementation of a Nb$_3$Sn 1-m-long, two-layer CCT single-aperture dipole, referred to as Canted Dipole One (CD1), which is designed to achieve a peak field in the bore of ~11 T.

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. [...]
