This award from the Instrumentation for Materials Research-Major Instrumentation Projects (IMR-MIP) program in DMR supports the construction of a revolutionary high field magnet, a "Series-Connected Hybrid" (SCH) magnet at the National High Magnetic Field Laboratory. The SCH is an innovative magnet and will use 1/3 of the power of a comparable resistive magnet. The magnet is composed of both superconducting and resistive magnets connected electrically in series. This series connection results in a uniquely flexible and efficient design and can operate in a high-field (greater than 40 Tesla) configuration, or a high homogeneity configuration. The homogeneity will improve by nearly 3 orders of magnitude compared with standard resistive and hybrid systems. Central to the design is the large superconducting magnet that produces part of the central field. The remaining magnetic field contribution is produced by the resistive magnet located inside of the superconducting magnet. The connection of a relatively high-inductance superconducting magnet to a resistive magnet greatly improves the field quality by reducing the temporal ripple. Because of the reduction in power consumption, significantly lower operating cost is attainable and longer continuous operations are possible. These will lead to increased scientific productivity. The unique features of the SCH result in many advantages for the science community. Longer run times allow for longer data acquisition at high fields. Greater field stability reduces noise bringing improved sensitivity to most experiments. The higher field improves resolution and contrast in resonance and imaging. The magnet will be used as a tool primarily for the characterization of material properties and resonance imaging. In the area of condensed matter physics, electronic, magnetic, optical, and superconducting properties of materials will be measured. For chemistry, inorganic metal oxides, catalysts, conductors, semiconductors, and biocompatible surfaces will be characterized. Also for biological studies, membrane protein structures will be determined and studies will be performed using high-resolution magnetic resonance microscopy. The SCH project will involve both undergraduate and graduate students from the joint Florida State University/Florida A&M University College of Engineering (FSU/FAMU CoE) as well as from the physics and chemistry departments of these and other institutions. FAMU is an HBCU.

该奖项来自DMR的材料研究仪器-主要仪器项目（IMR-MIP）计划，支持在国家高磁场实验室建造革命性的高磁场磁体，即“串联混合”（SCH）磁体。SCH是一种创新的磁铁，将使用1/3的可比电阻磁铁的功率。 该磁体由串联的超导磁体和电阻性磁体组成。 这种串联连接导致独特的灵活和高效的设计，并且可以在高场（大于40特斯拉）配置或高均匀性配置中操作。与标准电阻和混合系统相比，均匀性将提高近3个数量级。该设计的核心是大型超导磁体，它产生部分的 中场 剩余的磁场贡献由位于超导磁体内部的电阻磁体产生。 相对高电感的超导磁体与电阻性磁体的连接通过减少时间涟漪而大大改善了场质量。由于功耗的降低，可以显著降低运行成本，并且可以实现更长时间的连续运行。这将提高科学生产力。 SCH的独特功能为科学界带来了许多优势。 更长的运行时间允许在高场进行更长的数据采集。 更高的磁场稳定性降低了噪音，提高了大多数实验的灵敏度。 更高的场提高了共振和成像中的分辨率和对比度。该磁体将主要用作材料特性表征和共振成像的工具。 在凝聚态物理学领域，将测量材料的电子，磁性，光学和超导特性。 对于化学，无机金属氧化物，催化剂，导体，半导体和生物相容性表面将被表征。 此外，对于生物学研究，将确定膜蛋白结构，并使用高分辨率磁共振显微镜进行研究。SCH项目将涉及来自联合佛罗里达州立大学/佛罗里达AM大学工程学院（FSU/FAMU CoE）的本科生和研究生，以及这些和其他机构的物理和化学系的学生。FAMU是HBCU。
