In a landmark achievement for fusion energy, ITER has completed all components for the world’s largest, most powerful pulsed superconducting electromagnet system.

ITER is an international collaboration of more than 30 countries to demonstrate the viability of fusion—the power of the sun and stars—as an abundant, safe, carbon-free energy source for the planet.

The final component was the sixth module of the Central Solenoid, built and tested in the United States. When it is assembled at the ITER site in Southern France, the Central Solenoid will be the system’s most powerful magnet, strong enough to lift an aircraft carrier.
