Continuing Testing of the ITER CS Modules

The ITER Central Solenoid (CS) is under fabrication by the US ITER organization and its subcontractors. US ITER will supply seven modules to ITER IO, six of which will be assembled in a stack that forms the ITER Central Solenoid. All CS modules (CSM) were or will be tested at 40 kA in the Final Test facility at General Atomics (GA). CSM 5, 6, and 7 were tested in 2023 and 2024. Some instrumentation was updated to obtain information on the suppression of the inductive noise in the CSMs at high dB/dt events, which will lead to improved quench detection and protection of the modules. All the standard tests performed on previous CSMs to validate the properties of the CSM have also been performed on CSMs 5-7 to confirm the consistency of the CSM properties for ITER CS. The Tcs margin demonstration was done for the first time at the GA Facility on CSM6. Test results and analysis are presented and discussed.
