The behaviour of cryogen-free MgB₂react and wind coils

Abstract

Although the critical temperature of MgB2 is far below those of HTS materials, its simple composition, its upper critical field, the lack of weak links and the low anisotropy make it an interesting material for magnet applications. The low cost of magnesium diboride and the rather simple conductor manufacturing process triggered the interest of the industry and at present conductors are available in km order lengths. MgB2 is a good candidate for MRI applications and also for particle accelerator magnet applications.
