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.

9817431这项小企业创新研究二期项目将建造一对高场混合偶极磁铁。在第一阶段，开发了分析技术和一般设计方法，以生产大型、高精度、高场(高达1.8T)混合铁轭/稀土偶极磁体。然后将这些新工具应用于一台紧凑型70 MeV循环电子加速器中，设计了一个1T可调谐的带反向条纹场的“盒”偶极子。第二阶段的研究将在第一阶段设计的基础上，建造这些磁铁，然后在加速器中进行安装和测试。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，因为它们的结构比传统电磁铁简单，而且性能优于传统电磁铁。消除磁铁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要求，同时以与传统电磁铁相当的资本支出提高了可靠性。
