An Initial Look at the Magnetic Design of a 150 mm Aperture High-Temperature Superconducting Magnet With a Dipole Field of 8 to 10 T

Summary

This paper presents an initial design study of a high-temperature superconducting REBCO dipole magnet with a 150 mm aperture, intended for application in future multi-TeV muon colliders. Using a canted cosθ magnet configuration to manage electromagnetic stresses, the authors model the magnet's performance characteristics across a 8–10 T field range and two operating temperatures (4.2 K and 20 K), providing technical input for REBCO magnet and conductor development for collider-ring applications.

UK applicability
