Summary
This paper describes the mechanical structure design for the Paul Scherrer Institut's Canted-Cosine-Theta superconducting magnet programme. The CCT technology offers inherent stress management benefits for high-field accelerator magnets, particularly Nb₃Sn designs, but requires careful external mechanical support to compensate for the current-density dilution caused by internal structural features. The authors present a bladder-and-key-based mechanical structure with associated two and three-dimensional finite element analyses and tolerance assessments.
UK applicability
This paper is not applicable to UK agricultural research or food systems. It addresses high-energy physics magnet engineering and has no relevance to farming, soil health, nutrition, or food production.
Key measures
Coil stresses, engineering current density, mechanical stiffness, tolerance analysis under loading, cooling, and powering conditions
Outcomes reported
The paper reports the design, analysis, and tolerance evaluation of an external mechanical structure (based on the bladder and key concept) for the Paul Scherrer Institut's Canted-Cosine-Theta magnet prototype, including two-dimensional and three-dimensional mechanical analysis across loading, cooling, and powering stages.
