Design of a Canted-Cosine-Theta Superconducting Dipole Magnet for Future Colliders
/ Caspi, Shlomo (LBL, Berkeley) ; Arbelaez, Diego (LBL, Berkeley) ; Brouwer, Lucas (LBL, Berkeley) ; Gourlay, Steve (LBL, Berkeley) ; Prestemon, Soren (LBL, Berkeley) ; Auchmann, Bernhard (CERN)
A four-layer canted-cosine-theta 16-T dipole has been designed as a possible candidate for future hadron colliders. The design maintains part of the future-circular-collider magnet requirements, i.e., a 50 mm clear bore and 16 T operating at 1.9 K. [...]

Electromechanical Design of a 16-T CCT Twin-Aperture Dipole for FCC
/ Auchmann, Bernhard (CERN) ; Brouwer, Lucas (LBL, Berkeley) ; Caspi, Shlomo (LBL, Berkeley) ; Gao, Jiani (PSI, Villigen) ; Montenero, Giuseppe (PSI, Villigen) ; Negrazus, Marco (PSI, Villigen) ; Rolando, Gabriella (CERN) ; Sanfilippo, Stéphane (PSI, Villigen)
Canted-cosine-theta (CCT) technology has been studied for its suitability for a future-circular-collider (FCC) main dipole in terms of magnetic and mechanical performance, electrothermal protectability, as well as efficiency. In this paper, we present lessons learnt from our search for efficient CCT solutions by means of two-dimensional (2-D) magnetic and mechanical simulations, discuss the 3-D periodic mechanical model, as well as 3-D electromagnetic analysis of the end regions.

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.

Mechanical Structure for the PSI Canted-Cosine-Theta (CCT) Magnet Program

Abstract: The Canted-Cosine-Theta (CCT) technology has the potential, by its intrinsic stress-management, to lower coil stresses in high-field accelerator magnets. This is especially relevant for Nb3Sn magnets, which may be subject to irreversible degradation if the coil stresses exceed critical values. [...]

Modeling of Quench Protection Concepts for Canted-Cosine-Theta Type High-Field Magnets
/ Gao, Jiani (PSI, Villigen) ; Auchmann, Bernhard (CERN ; PSI, Villigen) ; Brouwer, Lucas (LBNL, Berkeley) ; Pautz, Andreas (PSI, Villigen ; Ecole Polytechnique, Lausanne) ; Sanfilippo, Stephane (PSI, Villigen)
An innovative high-field superconducting magnet of Canted-Cosine-Theta (CCT) type has been proposed for Future Circular Collider 16 T dipole magnet design. The unique mechanical structure intercepts the accumulated forces lowering the stress on the windings, constituting intrinsic stress management in high-field Nb $_{3}$ Sn accelerator magnets. [...]

Quench Protection of a 16-T Block-Coil Dipole Magnet for a 100-TeV Hadron Collider Using CLIQ
/ Ravaioli, E (CERN) ; Ghini, J Blomberg (CERN) ; Datskov, V I (CERN) ; Kirby, G (CERN) ; Maciejewski, M (CERN) ; Sabbi, G (LBL, Berkeley) ; ten Kate, H H J (CERN) ; Verweij, A P (CERN)
Abstract:
Protection against the effects of a quench is a crucial challenge for 16-T-class superconducting dipole magnets for a future 100-TeV Hadron collider. To avoid damage due to overheating of the coil's hot spot, heat generated during the quench has to be homogeneously distributed in the winding pack by quickly and uniformly transferring to the normal-state voluminous coil sections.

High Gradient Nb$_{3}$Sn Quadrupole Demonstrator MKQXF Engineering Design
/ Kokkinos, Charilaos (EAC Engineering P.C., Patras) ; Karppinen, Mikko (CERN)
The future upgrades of the CERN accelerator chain along with the future high-energy colliders, notably the future circular collider (FCC), will require high gradient quadrupoles. As part of the High Luminosity Large Hadron Collider (HL-LHC) project, the 11 T dipole was designed to be compatible with accelerator requirements and industrial production. [...]

The Future Circular Collider (FCC) study at CERN is investigating the design of a proton-proton collider with a center of mass energy of 100 TeV and a tunnel circumference of 100 km (FCC-hh). Nb_3Sn arc dipoles with 50-mm aperture and 16-T operating field are required for this application. [...]

Superconducting Curved Canted–Cosine–Theta (CCT) for the HIE-ISOLDE Recoil Separator Ring at CERN
/ Kirby, G (CERN) ; Rodin, V (Liverpool U.) ; Kirby, O (Exeter U.) ; Foussat, A (CERN) ; Resta-Lopez, J (Valencia U.) ; Martel, I (Huelva U.) ; Welsch, C (Liverpool U.)
The ISOLDE facility at CERN delivers the largest range of low-energy radioactive beams, exploited by several detector systems to investigate nuclear properties from the stable isotopes to the very exotic systems close to the neutron or proton drip lines. These studies can largely benefit from the use of a high-resolution fragment separator. [...]
