In a significant step forward for fusion energy, the ITER reactor project in Southern France has completed all major components for its superconducting magnet system. This accomplishment is a turning point for the world's largest fusion experiment, demonstrating the feasibility and scalability of replicating the Sun's energy. The final module of the Central Solenoid, ITER's most powerful magnet, is now ready for assembly. This magnet system drives the fusion process at ITER, aiming to produce clean, safe, and virtually limitless energy. ITER, a global partnership involving over 30 countries, harnesses nuclear fusion to create a carbon-free energy source. The Tokamak chamber, at the core of ITER, superheats hydrogen isotopes to achieve fusion without long-lived radioactive waste. The pulsed superconducting magnet system enables fusion by fuel injection, ionization, magnetic containment, extreme heating, and fusion ignition. The Central Solenoid, completed in the United States, is crucial for initiating and maintaining the plasma current within ITER's Tokamak. International collaboration from entities like the US, Russia, Europe, China, Japan, Korea, and India has been instrumental in constructing the magnet system. ITER's achievement signifies progress towards commercial fusion energy, offering a real-world testing ground for future fusion power plants. The completion of the magnet system signals a step closer to practical fusion energy, emphasizing global cooperation and a commitment to a sustainable energy future.
