The next generation

2025-11-05 - The 2025 PhD event of the European Fusion Education Network FuseNet takes place at ITER in November. Approximately 150 fusion students and researchers take part in the three-day program, with lectures, roundtables, site vists, networking, Pecha-Kucha-style presentations, and poster sessions.

2025-11-04 - Within the grasp of a bespoke lifting tool, a 110-tonne superconducting magnet for the central solenoid begins its ascent to the top of the stack where it will join four others.

2025-11-04 - The penultimate module of the central solenoid stack is lifted into place on 4 November. One more of these superconducting modules will bring the tower-like central magnet of the ITER machine to its full height.

2025-11-03 - Two families of pipe bundles for the tokamak cooling water system (TCWS) have been positioned in this L3 bioshield opening above the machine. In all, there are 18 bioshield openings reserved for TCWS piping.

2025-11-03 - At the L3 level of the Tokamak Building, pipe bundles are inserted into waiting sleeves in the bioshield. The sleeves are part of "penetration assemblies" that seal the openings in the bioshield wall while allowing equipment to pass through to the tokamak.

2025-11-03 - This large lid is part of the cryochamber that will be used to test a selection of ITER superconducting magnets at the temperature of -269 °C (4 K). It waits on temporary supports for the start of commissioning activities.

2025-10-31 - Workers look small against the backdrop of the huge ITER vacuum vessel. Two of nine sector modules have been installed and a third is expected later this month.

2025-10-28 - The ITER tokamak pit, where the assembly of the ITER machine is underway. Around the top, near the rim, are arrival pipes for cooling water.

2025-10-28 - Looking down at a sector module—one-ninth of the plasma chamber built from two toroidal field magnets (thickest steel component), thin thermal shield panels, and a vacuum vessel sector (double-walled, with walls outlined in black tape).

2025-10-27 - Miter bends (photo) and expansion units are the first transmission line components for the electron cyclotron resonance heating (ECRH) system to be shipped to ITER by the US Domestic Agency. Transmission lines—built from 10 main components—will carry the high-intensity beams hundreds of metres between the radiofrequency sources and vacuum vessel port plugs. Photo: US ITER/ORNL

2025-10-24 - The 49 recipients of the 2025 ITER Star Awards are celebrated on 24 October for exemplifying the ITER CARE values of Collaboration, Accountability, Respect, and Excellence.

2025-10-18 - Stefan Jachmich is the coordinating scientist for disruptions in ITER's Experiments & Plasma Operation Section. On 18 October, at the 30th IAEA Fusion Energy Conference in Chengdu, China, he is awarded the prestigious "Nuclear Fusion" journal award for a paper validating shattered pellet injection as a key method for disruption mitigation.

2025-10-16 - The ITER stand at the 30th IAEA Fusion Energy Conference in Chengdu, China, serves as a central meeting point for the ITER delegation and colleagues between technical presentations, poster sessions, and networking events. Nearly 2,000 fusion experts, scholars, and industry representatives from 61 countries are attending this premier biennial gathering.

2025-10-14 - The first four completed divertor cassettes, manufactured by the SIMIC–CNIM consortium for the European Domestic Agency Fusion for Energy, have successfully completed factory acceptance testing, including hot helium leak tests. The first units are expected at ITER in 2026.
