Description
Cost-effective superconducting dipole magnets with operating fields up to 16 T are being considered for the LHC energy upgrade (HE-LHC) or a Future Circular Collider (FCC). To demonstrate feasibility of 15 T accelerator quality dipole magnets, Fermilab as a part of US-MDP has started the development of a single-aperture Nb3Sn dipole demonstrator based on a 4-layer graded cos-theta coil with 60 mm aperture and cold iron yoke. In parallel, to explore the limit of the Nb3Sn accelerator magnet technology, optimize magnet design and performance parameters, and reduce magnet cost, magnet design studies are also being performed based on 3- and 4-layer 50 mm aperture cos-theta coils with and without stress management elements. Results of these studies are reported and discussed in this paper.
