In hadron colliders, they are used needed for beam separation before and after interaction points. In a muon collider, they are considered for both the arc and the interaction regions to provide room for internal absorbers protecting magnets from the muon decay products. These magnets can also be used in test facilities to produce a background magnetic field for testing conductor samples or insert coils. High level of magnetic field and large aperture size lead to large Lorentz forces and mechanical strains and stresses which can damage brittle Nb3Sn coils. This paper describes conceptual designs of 120-mm aperture dipoles with magnetic fields up to 15 T based on cos-theta coils. Stress management technique and magnet parameters are also presented and discussed.

Large-aperture high-field dipole magnets based on Nb3Sn superconductor are necessary for various accelerator systems of future hadron and muon colliders. In hadron colliders, they are used needed for beam separation before and after interaction points. In a muon collider, they are considered for both the arc and the interaction regions to provide room for internal absorbers protecting magnets from the muon decay products. These magnets can also be used in test facilities to produce a background magnetic field for testing conductor samples or insert coils. High level of magnetic field and large aperture size lead to large Lorentz forces and mechanical strains and stresses which can damage brittle Nb3Sn coils. This paper describes conceptual designs of 120-mm aperture dipoles with magnetic fields up to 15 T based on cos-theta coils. Stress management technique and magnet parameters are also presented and discussed.

Nb3Sn dipole magnets with a nominal field of 16 T and sufficient operation margins are being considered for the LHC energy upgrade or a future Very High Energy Hadron Collider.

This paper describes the conceptual design of a 17 T dipole magnet with 60 mm aperture and 4-layer cos-theta coil being developed at Fermilab. The results of magnetic and mechanical analyses, including the non-linear effects in magnetic field and the possible stress management techniques, are also presented and discussed.
