AB  - High temperature superconducting materials are currently utilised to generatethe magnetic fields required for the confinement of plasma in fusion reactors.The present study aims to assess the microstructural degradation resulting fromion implantation at room temperature with 2 MeV Xe+ ions to a total fluence of1 x 1016 ions/cm2 in Yttrium Barium Copper Oxide (YBCO) using high-resolutioncharacterisation techniques. Atom Probe Tomography (APT) and TransmissionElectron Microscopy (TEM) analyses were performed and correlated withalterations in superconducting behaviour measured using a Magnetic PropertiesMeasurement System (MPMS). TEM analysis was performed to depth-profile thedegree of crystallinity on irradiated samples. The maximum-damage layer wasfound 800 nm below the sample surface. Ion implantation caused thesuperconducting temperature to decrease by 10 K and the critical currentdensity to display a 10-fold reduction.
