Abstract
In this paper, we report our progress in the development of a low cost, liquid-helium-free MgB superconducting MRI magnet. Several technical issues related to the construction of such a magnet to operate in persistent current mode are discussed, namely, the performance consistency of long length MgB conductors, the fabrication of superconducting joints and persistent current switches. Quench detection and protection of such magnets operated in solid nitrogen environment are also discussed.
摘要
在本文中，我们报告了我们在开发一种低成本、无液氦的MgB超导磁共振成像（MRI）磁体方面取得的进展。讨论了与构建这种以持续电流模式运行的磁体相关的几个技术问题，即长长度MgB导体的性能一致性、超导接头和持续电流开关的制造。还讨论了在固体氮环境中运行的此类磁体的失超检测和保护。
