Abstract:
2G High-temperature superconducting (HTS) cable with high current capability has become the most attractive solution for large magnets operated under high fields and low temperatures. The Rutherford cable (Rfc) is one of the prospective options. This paper proposes a design of the Rfc that has a copper core and 10 2G HTS Quasi-isotropic Strands (Q-ISs). Then, a mathematical geometry method rapidly establishes the cable's three-dimensional (3D) model, which considers the strand number, the cable core's thickness, the cable's twist pitch, and the strand's laying angle. Based on the 3D model, to evaluate the HTS cable's mechanical performance, the simulations of the flat Rfc under axial tensile loads are implemented by the finite element method (FEM). The analyzed results provide important guidance for manufacturing the proposed Rfc and supply another candidate for applying large high-field magnets in the future.
