Description
Cable-In-Conduit-Conductor (CICC) is particularly suitable for applications requiring both high magnetic fields and efficient current transmission, such as in particle accelerators, magnetic resonance imaging (MRI) systems, and high-field magnets. To further enhance the current-carrying capability of CICC, we developed a CICC conductor in which the CORC strands are made up of 24 layers, with a total of 66 YBCO tapes. A CICC sample consists of two CORC strands and four copper strands is fabricated and then tested at 77K and self-field in straight form. Subsequently, numerical studies of current-carrying capability and magnetic behavior of the CICC sample are carried out by employing a H-formulation model in COMSOL. The measured critical currents are close to the simulation results, reaching about 12 kA. This study demonstrates that increasing the number of YBCO tapes in the CORC strands effectively enhances the current-carrying performance of the CICC.
