/ Lechner, Anton (CERN) ; Amorim, David (CERN) ; Bottura, L (CERN) ; de Sousa, P Borges (CERN) ; Caiffi, B (INFN, Genoa) ; Calzolari, D (CERN) ; Carli, C (CERN) ; Ferreira Somoza, J (CERN) ; Frasca, A (CERN) ; Lerner, G (CERN) et al.
Circular muon colliders provide the potential to explore center-of-mass energies at the multi-TeV scale within a relatively compact footprint. Because of the short muon lifetime, only a small fraction of stored beam particles will contribute to the physics output, while most of the muons will decay in the collider ring. [...]

/International Muon Collider Collaboration
Magnets have been identified as one of the critical technologies for a proton-driven Muon Collider. Within the scope of the International Muon Collider Collaboration we have progressed in the review of requirements, and the development of concepts towards the initial engineering of several of the most critical magnets identified from our previous work.

Magnets for a Muon Collider—Needs and Plans
/ Bottura, L (CERN) ; Accettura, C (CERN) ; Amemiya, N (Kyoto U.) ; Auchmann, B (PSI, Villigen) ; Berg, J S (Brookhaven Natl. Lab.) ; Bersani, A (INFN, Genoa) ; Bertarelli, A (CERN) ; Boattini, F (CERN) ; Bordini, B (CERN) ; Borges de Sousa, P (CERN) et al.
We describe the magnet challenges for a Muon Collider, an exciting option considered for the future of particle physics at the energy frontier. Starting from the comprehensive work performed by the US Muon Accelerator Program, we have reviewed the performance specifications dictated by beam physics and the operating conditions to satisfy the accelerator needs.

Protecting the magnets in case of a quench is a challenge for the 16 T superconducting dipole magnets presently designed for the 100 TeV: Future Circular Collider (FCC). These magnets are driven to the foreseen technological limits in terms of critical current, mechanical strength and quench protection. [...]

The Development of MBRD Magnets, the Separation/Recombination Dipoles for the LHC High Luminosity Upgrade
/ Farinon, Stefania (INFN, Genoa) ; Angius, Silvano (ASG Supercond., Genova) ; Barutti, Alberto (ASG Supercond., Genova) ; Bersani, Andrea (INFN, Genoa) ; Bracco, Michela (Genoa U. ; INFN, Genoa) ; Caiffi, Barbara (INFN, Genoa) ; Fabbricatore, Pasquale (INFN, Genoa) ; Fiscarelli, Lucio (CERN) ; Foussat, Arnaud (CERN) ; Gagno, Andrea (Genoa U. ; INFN, Genoa) et al.
As part of the high-luminosity upgrade of CERN LHC accelerator project, the National Institute of Nuclear Physics (INFN) in Genoa, Italy, has developed the MBRD separation-recombination dipole, also known as D2, whose function is to bring beams into collision before and after the interaction regions of the CMS and ATLAS experiments. It is a NbTi cos-theta double aperture dipole that generates a 4.5 T field in a 105 mm aperture, with a magnetic length of 7.78 m, and has the specific feature that the magnetic field in the two apertures is oriented in the same direction.

Validation of the Protection Scheme for the HL-LHC MBRD Magnet by Simulations and Prototype Tests
/ Caiffi, Barbara (INFN, Genoa) ; Bender, Lennard (Hochschule, Eng. Econ., Karlsruhe) ; Bersani, Andrea (INFN, Genoa) ; Bracco, Michela (INFN, Genoa) ; Farinon, Stefania (INFN, Genoa) ; Foussat, Arnaud (CERN) ; Gagno, Andrea (INFN, Genoa) ; Levi, Filippo (INFN, Genoa) ; Mangiarotti, Franco (CERN) ; Ninet, Gaelle (CERN) et al.
The High-Luminosity upgrade of the Large Hadron Collider (LHC) (Todesco et al., 2021) foresees the replacement of the magnets around the interaction points of the ATLAS and CMS experiments at CERN. One of the new magnets is the separation-recombination dipole, also called Main Bending Recombination Dipole (MBRD)(Caiffi et al., 2021), (Levi et al., 2022) in the D2 cryomagnet assembly. [...]

Analytical Evaluation of Dipole Performance Limits for a Muon Collider

Rome La Sapienza (main) ; INFN, Genoa) ; Bersani, Andrea (INFN, Genoa) ; Bottura, Luca (CERN) ; Caiffi, Barbara (INFN, Genoa) ; Fabbri, Siara (CERN) ; Farinon, Stefania (INFN, Genoa) ; Mariotto, Samuele (INFN, Milan ; Milan U. ; LASA, Segrate) ; Musenich, Riccardo (INFN, Genoa) ; Pampaloni, Alessandra (INFN, Genoa) ; Salmi, Tiina (Tampere U. of Tech.) et al.
Following the recommendation of the Updated European Strategy for Particle Physics, an International Muon Collider Collaboration has been formed and is currently studying the feasibility of a 10 TeV center-of-mass energy muon collider facility. Several technical challenges must be faced, mainly due to the limited muon lifetime at rest, 2.2 µs. [...]

The quest for advancing science and technology continues with the Future Circular Collider (FCC), which requires 16 T bending dipoles to be installed along its 100 km tunnel to achieve a center-of-mass energy of 100 TeV, in its hadron-hadron version. The promising Nb$_3$Sn technology for superconducting magnets presents a potential solution for large-scale production. [...]
