Dr. Joseph Minervini of the MIT Plasma Science and Fusion Center joins Priyanca Ford for a masterclass in the technology at the heart of magnetic confinement fusion. They cover why high-temperature superconductors like REBCO changed the game, the twin challenges of quench protection and structural stress, why tokamaks are inherently pulsed, and hard-won lessons from decades on ITER and the world’s largest superconducting magnet systems.
