Researchers at Berkeley Lab's Accelerator Technology & Applied Physics (ATAP) Division have developed a method for detecting and predicting the local loss of superconductivity in large-scale magnets that are capable of generating high magnetic fields. These high-field magnets are a core enabling technology for many areas of scientific research, medicine, and energy, where they are used in a range of applications, including in particle accelerators and colliders for high-energy and nuclear physics, diagnostic and therapeutic medical devices, and energy generation, transmission, and storage technologies.
