SBIR PHASE II: Construction of Large High-Field Permanent Magnet Dipoles

9817431 这个小企业创新研究第二阶段项目将构建一对高场混合偶极磁体。 在第一阶段的分析技术和一般设计方法的开发，以生产大型，高精度，高磁场（高达1.8 T）的混合铁轭/稀土偶极磁铁。 这些新的工具，然后应用于设计一个1 T的可调场的“盒”偶极子与反向边缘场用于紧凑的70 MeV的再循环电子加速器。 第二阶段的研究将基于第一阶段的设计，直接建造这些磁铁，然后将在加速器中安装和测试。 大型高场混合稀土偶极磁体可用于工业和研究加速器、束流传输线和光谱仪，因为它们的构造比传统电磁体简单，并且它们的性能上级于传统电磁体。 消除磁体线圈及其电源降低了电力消耗、维修成本、控制系统复杂性和空间需求，同时以与传统电磁体相当的资本支出增加了可靠性。

9817431 This Small Business Innovation Research Phase II project will be to construct a pair of high-field hybrid dipole magnets. In Phase I the analytical techniques and general design methodology were developed to produce large, high precision, high-field (up to 1.8 T) hybrid iron-yoke/rare-earth dipole magnets. These new tools were then applied to designing a 1 T tunable field 'box' dipole with a reversed fringe field to be used in a compact 70 MeV recirculating electron accelerator. The Phase II research will be directed toward constructing these magnets, based on the Phase I design, which will then be installed and tested in the accelerator. Large, high-field hybrid rare-earth dipole magnets can be used in industrial and research accelerators, beam transport lines, and spectrometers, as their construction is simpler than, and their performance is superior to, conventional electromagnets. Eliminating magnet coils and their power supplies reduces the electrical power consumption, servicing costs, control system complexity, and space requirements while increasing the reliability at a capital expenditure comparable to that of conventional electromagnets.
