HF RESONATOR
R&D for the development of the ITER ICRH system, aimed at testing radiofrequency window prototypes under operational conditions in the Tokamak WEST reactor.
The stainless steel parts have a copper coating on the surfaces in contact with the electromagnetic field, which is intended to improve the electrical conductivity of the material.
The mission's challenge
The combination of multiple factors and their complexity has led to significant investment in industrialization and methods to successfully manufacture components:
- pressure equipment
- ultra-high vacuum sealing
- copper deposition, surface treatments
- machining of complex parts
- dimensional accuracy
Specificity
A highly multidisciplinary project that brought together all the expertise within the Spirit Industries group.Technical characteristics
