Cryogenic structural material and design of support structures for the large helical device (LHD).

[In Japanese. / En japonais.]

Type of article: Article

Summary

The paper describes a short history of material selection for the cryogenic support structures for the LHD which has superconducting coils. Since the support structures are cooled down to 4.4 K together with the coils, SUS 316 was chosen because of its stable austenitic phase, sufficient mechanical properties at cryogenic temperature and good weldability. Outlines of the design and fabrication processes of the support structures are also summarized.
