该计划的目的是证明超导二硼化镁(MgB2)线与改进的上临界场(Hc2,)适合大规模应用。其基本思想是基于双间隙超导性来添加均匀分布的杂质,这些杂质将充当散射体,增加电阻率,从而增加Hc2。该提案的核心创新是基于最近由CI通过纳米SiC颗粒掺杂在MgB 2中取得的突破,其实现了块体形式的创纪录高Hc2和磁场中临界电流密度Jc的一个数量级的增强。预期的结果是开发具有高Hc2和Jc的超导MgB2导线和线圈用于MRI应用。
英文摘要
The aim of the program is to demonstrate the superconducting magnesium diboride (MgB2) wires with improved upper critical field (Hc2,) appropriate for large-scale applications. The basic idea will be based on the two-gap superconductivity to add well-distributed impurities which will act as scatterers, increasing resistivity, and thus Hc2. The core innovation of this proposal is based on the recent breakthrough in MgB2 that was made by the CIs through nano-SiC particle doping, which achieved a record high Hc2 in bulk form and enhancement of critical current density, Jc, in magnetic fields by an order of magnitude. The expected outcome is the development of superconducting MgB2 wires and coils with high Hc2 and Jc for MRI applications.
