New Animation Brings Central Solenoid to Life
Watch how invisible forces generated by the "heart of ITER" will help make fusion happen.
Central Solenoid
The US is responsible for 100% of the central solenoid (CS) magnet, including design, R&D, fabrication of 7 CS modules using supplied conductor (from Japan), associated structure, assembly tooling, bus extensions, and cooling connections.
The central solenoid serves as the backbone of the ITER magnet system. The CS induces the majority of the magnetic flux change needed to initiate the plasma, generate the plasma current, and maintain this current during the burn time. The CS is made of six independent coil packs that use a niobium-tin (Nb3Sn) cable-in-conduit superconducting conductor, held together by a vertical pre-compression structure. The conductor will be produced in unit lengths up to 910 m. The US is responsible for the 6 modules of the CS, a spare module, and the structure that ties them together and links these modules to the rest of the magnet system.

CS tests and verifications prior to assembly
In January next year, the "most powerful magnet in the world" will begin taking shape. The first module of the Tokamak's central solenoid will be positioned on a bespoke platform and the assembly process will begin in the ITER Assembly Hall. One by one, the six modules that make up the 18-metre tall, 1,000-tonne component will be stacked one upon the other and held together by a sets of tie plates (18 exterior and 9 interior).

US ITER wraps up a year of technical achievements and record contracts
Despite the pandemic, US ITER made great strides over the past year.
ITER Project ~75% Complete for First Plasma; Central Solenoid Module Deliveries Underway
The first two poloidal field coil magnets have been positioned in the tokamak pit.
First-of-a kind superconducting magnet en route to ITER site
The first of six superconducting magnet modules for the ITER central solenoid left General Atomics’ Magnet Technologies Center in Poway, California for the ITER site in France. The second module will depart later this summer. The international ITER fusion facility under construction in France has already begun initial tokamak assembly activities; the central solenoid is expected to be installed in 2023.
Strong bonds: MPEX magnet system benefits from US ITER expertise
As Oak Ridge National Laboratory’s Material Plasma Exposure eXperiment (MPEX) prepares for the start of fabrication, ORNL’s Phil Ferguson credits US ITER staff for sharing hard-earned expertise to help jump-start the design of the MPEX superconducting magnet system.
