论文摘要
Halbach磁铁是封闭体积中均匀磁场的来源，同时将流浪场保持在最低限度。在这里，我们介绍了10厘米内直径双Halbach环的设计，构造和表征，可提供约105吨约105吨的均匀性（在1 x 1 x 0 x 0.5 cm3上）的均匀（<100 ppm），该磁场将用于基于钻石的微波微波无需的无钻石宽阔的广场成像设置。最终表征是在3D翻译阶段的新型纤维化钻石传感器上进行的，该传感器记录了构造的Halbach阵列的高均匀性及其对拟议使用的适用性。
Halbach magnets are a source of homogeneous magnetic field in an enclosed volume while keeping stray fields at a minimum. Here, we present the design, construction, and characterization for a 10 cm inner diameter double Halbach ring providing a homogeneous (<100 ppm over 1 x 1 x 0.5 cm3) magnetic field of around 105 mT, which will be used for a diamond based microwave-free widefield imaging setup. The final characterization is performed with a novel fiberized diamond-based sensor on a 3D translation stage documenting the high homogeneity of the constructed Halbach array and its suitability for the proposed use.
