Superconductor showdown: Two fusion magnet rivals face intense radiation test

Researchers tested two superconducting materials, Bi-2212 and Nb3Al, under identical radiation conditions to see which could better withstand the harsh environment inside future fusion reactors. Bi-2212 broke down completely within 50 minutes, losing its crystal structure entirely, while Nb3Al held its structure after 90 minutes. The results give scientists a clearer starting point, but more testing under fusion-specific conditions is still needed.
