      Bridge-type mechanical lap joint with indium insertion between REBCO tapes is planned to be utilized for joint-winding of high-temperature superconducting (HTS) helical coils in heliotron-type fusion reactors, such as FFHR-d1 [1]. Shear strength evaluation of single lap joints using tensile shear testing at 77 K, self-field has been conducted to discuss if the joints can keep their performance...

      Poster

      In the design of DC busbar flexible connection in Power Supply System of CRAFT (Comprehensive Research Facility for Fusion Technology，China), water-cooled aluminum busbars interconnections are connected through aluminum flexible connectors to compensate for thermal expansion and Installation deviation. As the contact surface between the DC busbar and the flexible connection is very small, the...

      High-quality joints are essential for building practical assemblies of fusion-scale magnets, integrating the magnets with bus and leads, and allowing modularity in magnet design. The essential figure of merit for the quality of the joint is its electrical resistance which should be as low as possible. Due to its low bulk resistivity and high ductility, indium is often used to cold-weld the...
