Multiscale structural assessment of toroidal field coils via reduced-order models

Lorenzo Zoboli et al.

Summary: This paper investigates the effectiveness of reduced-order models in analyzing the mechanical response of Toroidal Field Coils (TFC) when non-ideal shapes are considered. Different beam models, based on different treatments of shear and bending effects, are introduced. A bottom-up homogenization technique is used to account for the subscale arrangement of TFC components, providing quantitative indications on average localisation effects. The beam-like approaches are validated by comparing with detailed finite element models, showing their reliability in preliminary design stages.

Magnetic and Electromechanical Characterization of a High-JC RRP Wire for the HL-LHC MQXF Cable

Gianluca De Marzi et al.

Summary: In this study, the electromechanical performance of a 0.85 mm diameter RRP wire procured for the HL-LHC project was evaluated through a series of inductive and transport measurements. The results showed that the critical current of the wire is influenced by the magnetic field, temperature, and strain, providing an important reference for magnet design.

Design Studies, Magnetic Calculations and Structural Assessment For the DTT Central Solenoid

Lorenzo Giannini et al.

Summary: The DTT is an experimental fusion reactor being built in Frascati, Italy, with a Central Solenoid that operates in a pulsed regime to induce plasma current. The design of the Central Solenoid is optimized using the Design Explorer algorithm to maximize magnetic flux density and minimize mechanical stress. This manuscript includes electromagnetic calculations, structural assessments, and analyses for the qualification of main components of the CS structure.
