/ 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.

R2D2, the CEA Graded Nb$_3$Sn Research Racetrack Dipole Demonstrator Magnet
/ Calvelli, Valerio (IRFU, Saclay) ; Mallon, Philip (LBNL, Berkeley) ; Durante, Maria (IRFU, Saclay) ; Felice, Helene (IRFU, Saclay) ; Rochepault, Etienne (IRFU, Saclay) ; Manil, Pierre (IRFU, Saclay) ; Minier, Gilles (IRFU, Saclay) ; Rifflet, Jean-Michel (IRFU, Saclay) ; Perez, Juan (CERN)
As a part of a collaborative effort with CERN on the long road to FCC-hh, CEA is developing a 1.4 m-long single aperture short dipole demonstrator. This Nb$_3$Sn block dipole, named F2D2, is foreseen to produce 15.5 T with a 14% margin at 1.9 K, and will use a shell-based support structure. [...]

Chapter 2: High-field magnets
/ Védrine, P (Saclay) ; García-Tabarés, L (Madrid, CIEMAT) ; Auchmann, B (PSI, Villigen) ; Ballarino, A (CERN) ; Baudouy, B (Saclay) ; Bottura, L (CERN) ; Fazilleau, P (Saclay) ; Noe, M (KIT, Karlsruhe) ; Prestemon, S (LBNL, Berkeley) ; Rochepault, E (Saclay) et al.
High-field magnets (HFM) are among the key technologies that will enable the search for new physics at the energy frontier. Approved projects (HL-LHC) and potential future circular machines such as proton-proton Future Circular Collider (FCC-hh) and Super proton-proton Collider (SppC) require the development of superconducting (SC) magnets that produce fields beyond those attained in the LHC.The programme proposed here rests on the results achieved over the past twenty years of European and international programmes devoted to Nb$_{3}$Sn and HTS accelerator magnets, such as CARE, EuCARD, EuCARD2, ARIES and the recently launched I-FAST.

In the framework of a design study for a post-LHC 100 TeV circular hadron collider, namely FCC-hh, high-gradient Nb$_3$Sn lattice quadrupoles were investigated, following closely the specifications from the optic layout of that machine. After several iterations, a baseline design of the main quadrupole was selected and, then, included in the FCC-hh Conceptual Design Report. [...]
