2025-08-06 - In August, the pre-production cryopump is used to commission the cryopump test facility. The test bench creates vacuum and cold conditions similar to ITER operation, allowing the teams to test the pump in different ITER scenarios. Next: at least four of the production cryopumps will be tested.

2025-07-07 - At the top of the three-floor Radiofrequency Building, 24 gyrotrons will be installed in three rows of eight. The first to be installed is a gyrotron delivered by Japan, which will be in place and connected to its power supply by late August.

2025-06-18 - The second of nine modules required to form the ITER plasma chamber is installed in the tokamak assembly pit on 17-18 June 2025. Sector modules #7 and #6 are now side by side in the pit, with 15 cm between them.

2025-04-10 - The first of nine modules required to form the ITER plasma chamber is installed in the tokamak assembly pit on 10 April. Sector module #7 was created from one vacuum vessel sector, its thermal shield and two toroidal field coils in 6 months and 10 days; for reference, the first time this sub-assembly operation was carried out it took 18 months to accomplish.

2025-03-28 - Sector module #7 is the first to be finalized, a litte ahead of schedule, after vacuum vessel sub-assembly restarted in September 2024. It will be lowered into the tokamak pit in April, the first of nine modules required to form the ITER plasma chamber.
