Summary
This paper presents detailed finite element modelling of a hybrid Nb₃Sn/Bi-2212 superconducting dipole magnet being developed at Fermilab as part of the US Magnet Development Program. The authors compare heterogeneous and homogeneous conductor models and implement a Python-based simulation incorporating current degradation due to mechanical stress in the HTS conductor during energisation. The analysis provides electromagnetic and mechanical characterisation of the 2D cosine-theta magnet design intended to achieve 20 T bore field.
UK applicability
This work is relevant to UK research institutions involved in high-energy physics infrastructure and superconducting magnet development, though the specific application (US-MDP collaboration) is US-based. UK participation in international magnet research programmes may benefit from the methodological advances presented.
Key measures
Magnetic field distribution, mechanical stress, current degradation in LTS and HTS conductors, Lorentz forces, conductor stress-strain behaviour
Outcomes reported
The study reports 2D electromagnetic and mechanical finite element analysis results of a hybrid LTS/HTS cosine-theta dipole magnet, including comparison between detailed heterogeneous and homogeneous conductor models and simulation of current degradation due to stress.
