Talk title: Radiation damage of high temperature superconductors for fusion magnets

Susie Speller is a Professor of Materials Science at the University of Oxford where she leads the Superconducting Materials research group and co-directs the Oxford Centre for Applied Superconductivity. Over the last 20 years, she has worked on a wide variety of superconducting materials, ranging from superconducting solders for persistent mode joints to high temperature superconducting cuprates and iron-based materials. Her research focuses on correlating processing with microstructure and superconducting properties using advanced microscopy and spectroscopy techniques. She is currently undertaking a 5 year EPSRC Fellowship to study irradiation damage of coated conductors for compact fusion applications. Her group has carried out pioneering in situ experiments to measure the effects of cryogenic irradiation on superconducting properties, as well as investigating the nature of irradiation-induced defects using the combination of atomic-resolution electron microscopy, synchrotron x-ray absorption spectroscopy and density functional theory. She enjoys working closely with industrial collaborators and national laboratories, including Tokamak Energy, United Kingdom Atomic Energy Authority (UKAEA), Oxford Instruments and Siemens Healthineers, on industrially-relevant projects. Susie is currently the Letters Editor for Superconductor Science and Technology and has published a book for the general audience: “A materials science guide to superconductors: and how to make them super”.
