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...
The Central Solenoid (CS) coaxial joint is an electrical connection designed to link the terminals of the CS module to their busbar extensions. This paper outlines the manufacture and testing of the CS coaxial joint Production Proof Samples (PPS), during the CS module stacking process. Once the PPS was completed, it was sent by the ITER Organization (IO) to the CEA. Detailed and increasingly...
Feeders, as key components located on the upper and bottom of ITER tokomak, provide power supply, cooling and signal measurement to ITER superconductive magnets (PF, TF and CC coils). The installation of Feeder joints consists of three major stages (joint assembly, joint insulation, mechanical installation) and hundreds of precise operations, and involves thorough planning, engineering,...
The ITER Feeder joints, as critical connections between the Feeders and the superconducting magnet system, play a vital role in ensuring the system's safety and stability. The on-site joint insulation process is a core task to meet design objectives and ensure operational reliability. Since the Feeder joint insulation work began in September 2022, significant progress has been made despite the...
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...
