Abstract

Thermal insulation for use in support systems for superconducting fusion magnets in radiation environments has been investigated. To develop a high-performance support system, we determined the cryogenic characteristics of advanced composites materials, such as those reinforced with alumina or carbon fibers, and designed model systems based on their characteristics. Thermal performance was influenced mainly by fiber selection. Mechanical performance, strength as well as the rigidity, were evaluated in terms of support-system requirements. The effects of radiation on the support systems were also assessed on the basis of damage resulting from irradiation of the materials.
