General Atomics in San Diego, Calif., is overseeing the fabrication of the central solenoid, including the development of specialized tooling stations. This de-spooling tool—being developed by Tauring in Torino, Italy—will become part of the part of the conductor winding station at GA. Photo: General Atomics

Sample conductor, which is not superconducting, has been delivered to General Atomics in preparation for fabrication of the mock-up module Photo: US ITER
