Demonstration of $\text{MgB}_{2}$ React-and-Wind Coil
The critical temperature of $\text{MgB}_{2}$ exceeds that of NbTi, making it a superior choice for superconducting applications. By utilizing liquid hydrogen instead of liquid helium for cooling $\text{MgB}_{2}$ coils, the cost of cooling can be reduced greatly, particularly when combined with hydrogen technology. In addition, in cryogen-free magnets, $\text{MgB}_{2}$ coils offer energy-saving benefits as the cooling efficiency increases with the operating temperature. The use of $\text{MgB}_{2}$ wires in superconducting applications becomes feasible when considering cost advantages. The react-and-wind (R&W) method can reduce the manufacturing cost by eliminating the need for a furnace for coil heat treatment and enables the use of impregnated resins and supports without concerns regarding high-temperature durability. We fabricated an R&W $\text{MgB}_{2}$ coil with a minimum radius of 55 mm. This paper presents the details of the fabricated coil and measurement results.
