Diagnostics Magnetics Inner Vessel Coils (IVC) are inductive magnetic sensors to measure local magnetic field in various frequency ranges. They are located on the inner surface of the ITER Vacuum Vessel (VV) in a high vacuum environment and nominal operating temperature of 150 C. The IVCs include 6 assemblies with each assembly comprising of a sensor head (pick-up coil) and a platform. The scope of this procedure relates to the supply of High-Frequency (HF) sensor heads for the IVC assemblies and includes:

— preparation for manufacture of the sensor heads,

— manufacture of sensor heads, and

— testing, cleaning, packaging and delivery of the sensor heads.
