Description
In superconducting applications such as NMR/MRI, SMES, and fusion reactor systems, the critical current (Ic) of the wire is an essential component in determining device performance. This critical current depends on the applied magnetic field (B) and temperature (T), and particularly exhibits magnetic anisotropy in tape-shaped HTS. SuNAM, a manufacturer of HTS wire, operates a 4 Tesla Ic(B, T) measurement system to evaluate the characteristics of the developed wire and ensure product quality, while currently establishing a new 8 Tesla system. This presentation provides an overview of the design, fabrication, and testing results of the magnet utilized for applying the magnetic field in the Ic(B, T) system. The magnet, constructed with HTS coils, uses No-insulation winding techniques with wires of 4, 6, and 8 mm in width. The warm bore of the magnet has a diameter of 70 mm, and the system will be completed in combination with an insert probe under development.
