Overview

• The Institute of Plasma Physics at the Chinese Academy of Sciences confirmed a steady 35.1‑tesla field, surpassing the prior 32.35‑tesla superconducting record set by another CAS division.
• The field strength equals about 351,000 gauss, roughly 700,000 times Earth’s magnetic field according to the institutes’ announcement.
• The magnet maintained stable operation for about 30 minutes and was then safely demagnetized, demonstrating reliability for sustained use.
• Researchers report resolving key low‑temperature, high‑field engineering issues including stress concentration, shielding‑current effects, and multi‑field coupling.
• The team includes ASIPP, the Hefei International Applied Superconductivity Centre, the Energy Research Institute of the Hefei Comprehensive National Science Centre, and Tsinghua University, with ASIPP noting localized superconducting supply chains and its role supplying ITER components.
