Summary
This paper documents the development and validation of a finite element analysis model for a 15-T Nb₃Sn superconducting dipole magnet demonstrator being developed by Fermilab for potential use in future high-energy physics accelerators. The magnet design incorporates a novel mechanical structure—a vertically split iron yoke supported by aluminium clamps and a stainless steel skin—to manage the extreme Lorentz forces at 15 Tesla. The parametric FEA model and sensitivity analysis provide insights into how geometrical tolerances and assembly variations affect structural integrity and performance.
UK applicability
This research has limited direct applicability to UK agricultural or food systems contexts. It may be relevant to UK-based particle physics research infrastructure or engineering programmes requiring high-field magnet technology, but falls outside the scope of farming systems and human nutrition.
Key measures
Lorentz force distribution, stress and strain in magnet structure components, effects of geometrical tolerances and assembly parameters on structural performance
Outcomes reported
The study presents a parametric multiphysics finite element analysis model of a 15-T Nb₃Sn dipole demonstrator magnet and reports sensitivity analysis results for geometrical tolerances and assembly parameters affecting mechanical performance.
