Superconductor Showdown: Two Fusion Magnet Rivals Battle Radiation

Superconductor showdown: Two fusion magnet rivals battle radiation

Researchers compared two superconductors under identical radiation conditions, revealing a sharp difference in their structural stability.

Radiation Exposes a Resilience Gap Between Fusion Superconductors

Future fusion reactors will rely on superconducting magnets that must keep working for years while exposed to energetic particles. A new head-to-head irradiation study shows that two candidate superconductors can respond very differently under the same electron-beam conditions. The layered cuprate Bi-2212 progressively lost its crystalline order and became fully amorphous, whereas the A15 superconductor Nb3Al retained its crystal structure even after a substantially longer exposure.
