Description

The Cable-in-Conduit Conductor (CICC) is one of the core components in large-scale superconducting (SC) magnet systems, characterized by its multidisciplinary and technically complex nature. This paper investigated and developed a rectangular Bi2212 CICC to withstand high magnetic pressures in the CHMFL. Detailed analyses of its mechanical, stability, fabrication, and preliminary tests are presented. The Bi2212 CICC short-sample with 60 SC wires achieves nearly 40 kA at self-field. Test results demonstrate that the rectangular conductor, with low porosity (≤30%) and long twist pitch (stage-Ⅲ>145mm), still retains excellent performance even under large deformation with optimized aspect ratio. These findings highlight its promising potential for applications in high magnetic fields.
