"Ensuring the Safety of Superconducting Magnets"

Researchers at Berkeley Lab's Accelerator Technology & Applied Physics 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. The method employs an array of Hall probes to measure the magnetic fields produced around Rare-earth barium copper oxide (ReBCO) CORC cables. This innovative technique has the potential to serve as a key element in solving the quench protection for high-temperature superconductor cables, a fundamental issue for the scientific community working on the next generation of superconducting magnets.
