Abstract

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.

$\text{MgB}_{2}$反应-风力线圈演示

$\text{MgB}_{2}$的临界温度超过NbTi的临界温度，使其成为超导应用的理想选择。利用液氢代替液氦来冷却线圈，冷却成本可以大大降低，特别是与氢技术结合使用时。此外，在无低温磁体中，线圈提供节能效益，因为冷却效率随着工作温度的提高而提高。考虑到成本优势，在超导应用中使用$\text{MgB}_{2}$导线是可行的。反应-风力（R&W）方法可以降低制造成本，因为它不需要一个炉来进行盘管热处理，并且可以使用浸渍树脂和支架，而无需担心高温耐久性。我们制作了一个最小半径为55 mm的R&W $\text{MgB}_{2}$线圈。本文详细介绍了线圈的制作过程和测量结果。
