Finite element modelling and experimental measurement of the mechanical properties of Nb3Sn multi-filamentary composite superconducting wires
… and high field superconducting magnets are Nb3Sn multi-tilamentary composite wires. The mechanical properties of these wires can have a strong bearing on the capabilities of the magnets because their superconducting properties are strongly dependent on the strain state within the Nb3Sn. The …

Light scattering studies of phonon anomalies and superconductivity in A15 compounds
… mean free path. Raman scattering measurements on Nb3Sn, V3Si, and Niobium show for the first time new peaks in the superconduct1ng state close in energy to the superconducting gap 28. These are attributed to direct electronic Raman scattering by pairs of superconducting quasiparticles. A theory is …

Advanced Characterization of Materials for Superconducting Radiofrequency Accelerator Cavities
… in the first instance and coating with Nb3Sn in the second. Materials characterization is key to achieving understanding and directing RandD. However, very little has been done. This present work aims to fill the knowledge gap and to provide needed, validated tools to the accelerator …

Actively shielded air-core superconducting machines: optimization and design considerations
… is presented employing mature and low-cost Nb3Sn windings on a conduction cooled assembly. First, electromagnetic performance of the device is rigorously explored using evolutionary optimization techniques. Armature flux densities of up to 5 Tesla are shown to be achievable. Next, mechanical …

Nonlinear Dynamics of Vortices in Different Types of Grain Boundaries
… of SRF materials, particularly Nb and Nb3Sn, we performed extensive numerical simulations of nonlinear dynamics of Josephson vortices in grain boundaries under strong dc and RF fields. The RF power due to penetration of vortices both in weakly-coupled and strongly-coupled grain …
