Radiation Damage in High Temperature Superconducting Materials for Fusion applications

The toroidal field magnets of Magnetic Confinement Fusion (MCF) devices need to operate at high current density for cost effective operation, requiring the use of superconducting wires. To aid in the design of the toroidal magnets being proposed by this work’s sponsor, Tokamak Energy, this work aims to better understand how ReBCO superconductors will perform when subjected to the exotic particle environment present in MCF devices. This has been achieved using 2MeV He and 3.1MeV O ion irradiation as a proxy. A brief summary of the phenomenon of superconductivity is presented, along with results and conclusions from these two irradiation campaigns, and proposed future work.
