dc.description.abstract
An increase of the high field critical currents in commercial Nb3Sn wires by about 50 % is required for the design of Future Circular Collider (FCC) superconducting magnets. Creating additional flux pinning centers by means of fast neutron irradiation that induces defects in the crystal structure is one promising approach for reaching this target. In this study, the underlying mechanisms are investigated through combined microstructural and magnetic analyses. This knowledge is a requirement for manufacturing such high-performance superconductors in an industrial process. The nuclear research reactor of TU Wien was used to irradiate various Nb3Sn wires produced by different manufacturing techniques as well as transmission electron microscopy (TEM) specimens. Micro- and nanostructural examinations of grain geometry, grain boundary morphology, compositional gradients, local texture and defect structure were performed before and after irradiation by transmission electron microscopic methods such as high-resolution TEM (HRTEM), energy-dispersive X-ray spectroscopy (EDX), electron energy loss spectroscopy (EELS) and selected area diffraction. The results thereof are correlated with measurements of the superconducting properties, in particular scanning Hall probe experiments and SQUID magnetometry to determine the global critical current as well as the local critical current density within the superconducting subelements. The established correlation contributes to a better understanding of the influence of irradiation damage and the resulting microstructure on local superconducting properties and ultimately on the macroscopic performance of the superconductor.
