Description
Summary:The China fusion engineering test reactor is a new tokamak device. It is a commercial reactor, which demands a superconducting magnet with higher magnetic field. The maximum field of CS and TF will get around 15 T, which is much higher than that of present reactors. In order to meet the requirements, the new conductor with Bi2Sr2 CaCu2Ox is considered as one potential material for the superconducting magnets. Because Bi2212 wire needs to endure special heat treatment with oxygen, the jacket material is one key issue. As one new material, Ni80Cr has an excellent performance, which cannot react with Bi-2212 wire. It could be one potential material as Bi-2212 cable-in-conduit conductor jacket. In order to understand the mechanical properties of Ni80Cr, the samples with different conditions were prepared, and tested at high, room, and low temperature (4.2 K). The results are analyzed in this paper.
