US ITER is a DOE Office of Science project managed by Oak Ridge National Laboratory
With the successful lift of the final module at the end of June, the stacking of the central solenoid—the powerful magnet at the heart of the ITER tokamak—is now complete. While crucial technical work remains before the magnet is ready to be transferred into the tokamak pit, the completed stack is a milestone moment for […]
US ITER has completed final deliveries to the international ITER fusion project for the central solenoid, the world’s most powerful pulsed superconducting magnet. The most recent deliveries included a turnover tool for handling the 110-ton modules plus bus bars and leads for electrical connections between the modules. Earlier, all magnet modules, support structures and tooling […]
As of early 2026, US ITER has completed three technical systems for the international ITER fusion project: the central solenoid magnet system, the toroidal field coil conductor, and the steady state electrical network. The central solenoid was completed in April 2026 with the final deliveries of tooling and components. Previously the United States had completed […]
The spare central solenoid module arrived safely at the ITER site in mid-January after a weeks-long journey by boat and truck from the United States. “It’s very satisfying to see the transport executed so smoothly,” said Jeff Parrott, logistics and transportation coordinator for US ITER. “There will be other large components we deliver but none […]
The fifth module has been placed on the central solenoid magnet stack in the ITER Assembly Hall. See a video of the delicate operation of moving and positioning the 121-ton module into place. The sixth and final module, delivered to ITER in September, is scheduled to be moved into place at the top of the […]
The United States has delivered the sixth and final module needed to complete the central solenoid magnet of the ITER tokamak. The event marks the culmination of more than a decade of engineering design and fabrication of a first-of-its-kind pulsed superconducting magnet that will sit at the center of the ITER tokamak. “This is another […]
After a month’s long journey from the port of Houston, Texas, the fifth central solenoid module has reached the ITER site in southern France. Meanwhile, the sixth and final module needed to complete the central solenoid stack at ITER is now en route after successfully completing testing in the United States. Read the article.
After being transported by land to the port of Houston, Texas, the fifth central solenoid module has been loaded onboard an oceangoing vessel for transport to France. Manufactured by General Atomics in Poway, California, on behalf of US ITER, the module is expected to arrive at the ITER site later this month. The sixth and […]
US ITER and supplier General Atomics have finished testing the sixth and final module required for the 60-foot-tall superconducting magnet at the heart of ITER. Each cylindrical module is wound from ~3.5 miles of niobium-tin superconducting cable supplied by ITER Japan, with more than two years of precision fabrication and verification required. The final phase, […]
This week the fifth 110-tonne module of ITER’s central solenoid magnet was loaded at the manufacture site in California for transport to the ITER site in southern France. Manufactured by General Atomics on behalf of US ITER, the module is one of six being stacked vertically to form the central solenoid. Considered the heart of the […]
