AI Technical Summary
Technical Problem
High temperature superconductors (HTS) materials, such as REBCO, experience degradation of grain boundaries when exposed to neutrons and ions, leading to reduced critical current and performance in devices like MRI systems and nuclear fusion reactors, particularly at higher fluences and room temperature.
Method used
Exposing HTS materials to neutrons at cryogenic temperatures before incorporation into devices creates and enhances pinning sites, minimizing grain boundary degradation and potentially improving electrical characteristics.
Benefits of technology
This approach enhances the critical current density of HTS materials by forming pinning sites while reducing grain boundary degradation, allowing for more compact fusion reactors with reduced neutron shielding.
