Researchers at international magnetic confinement facilities have maintained stable high-temperature plasma for over six minutes, a critical threshold for net-energy fusion viability.
Superconducting Magnet Upgrades
The milestone was made possible by high-temperature superconducting magnets, which allow higher magnetic field density without increased electrical resistance.
Heat Exhaust Management
Engineers must now solve material degradation issues in the reactor divertor plates, which sustain heat flux comparable to solar surfaces.
