Summary
This paper documents the 3D mechanical design optimisation of F2D2, an innovative 15 T Nb₃Sn block-coil short-model dipole demonstrator being developed by CEA Paris-Saclay and CERN. The design work focuses on managing the technical complexity of splicing two cable grades outside the magnet and optimising the longitudinal pre-load system (via tie-rods and end-plates) to contain large Lorentz forces whilst minimising coil stress. The study demonstrates how advanced CAD and finite-element methods can resolve demanding engineering constraints in high-field superconducting magnet development.
UK applicability
This research is not directly applicable to UK farming systems, soil health, nutrient density or food production, as it concerns fundamental physics infrastructure development rather than agricultural or nutritional science.
Key measures
Operating field strength (15 T), pre-load levels, stress distribution in coils, Lorentz force containment, magnet end geometry optimisation
Outcomes reported
This paper reports the preliminary 3D mechanical design phase of F2D2, a 15 T Nb₃Sn block-coil dipole magnet prototype. The study optimised coil geometry, cable routing at magnet ends, and longitudinal pre-load systems using CAD and finite-element modelling.
