Summary
This paper describes design refinements to a 20 T hybrid superconducting dipole magnet intended for high-energy particle collider applications. The work builds on prior concepts by optimising both the magnetic performance and mechanical stress management of a block-coil configuration that combines low-temperature (Nb₃Sn) and high-temperature (Bi2212) superconductors. The authors demonstrate improved field quality and reduced peak stresses through enhanced stress-management geometry, with innovations in coil-end design presented as practical implementations.
