AI总结:

研究设计并制造基于十五个钕铁硼环优化堆叠结构的紧凑型永磁体,采用可调NS-SN-NS配置,为离子阱开发等提供高性能且经济高效的超导磁体替代方案。

摘要:

本文介绍了一种基于十五个钕铁硼环的优化堆叠结构的紧凑型永磁体的设计与制造。可调的NS-SN-NS配置在1mm半径的球形体积内产生0.8T的中心磁场,重建均匀性为99.988%。剩余场不均匀性由径向偶极分量主导。该设计无需低温技术和外部电源,为离子阱开发和傅里叶变换离子回旋共振质谱中的应用提供了一种高性能且经济高效的超导磁体替代方案。

英文摘要:

This work presents the design and fabrication of a compact permanent magnet based on an optimized stacked structure of fifteen NdFeB rings. The tunable NS-SN-NS configuration generates a central magnetic field of 0.8T with a reconstructed uniformity of 99.988% within a 1mm radius spherical volume. The remaining field inhomogeneity is dominated by radial dipole components. Requiring neither cryogenics nor external power, this design provides a high-performance and cost-effective alternative to superconducting magnets for applications in ion-trap development and Fourier-transform ion cyclotron resonance mass spectrometry.
