Summary

Large-aperture high-field superconducting (SC) magnets are used in various accelerator systems of particle accelerators/colliders. Large Lorentz forces and mechanical stresses can degrade or damage the brittle SC coils. The stress-managed cos-theta (SMCT) coil is a new concept for high-field and/or large-aperture accelerator magnets based on low-temperature and high-temperature superconductors. This concept was proposed and is being developed at Fermilab in the framework of the US Magnet Development Program (US-MDP). The SMCT structure is used to reduce the large coil deformations under Lorentz forces and, thus, the excessively large strains and stresses in the coil.
