IMR-MIP Series Connected Hybrid Construction Phase

该奖项来自DMR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一种革命性的高磁场磁铁，一种“串联混合”（SCH）磁铁。SCH是一种创新的磁铁，将使用1/3的可比电阻磁铁的功率。磁体由超导磁体和电阻磁体串联而成。这种串联连接具有独特的灵活高效的设计，可以在高场（大于40特斯拉）配置或高均匀性配置下运行。与标准电阻和混合系统相比，均匀性将提高近3个数量级。该设计的核心是产生部分中心磁场的大型超导磁体。剩余的磁场贡献是由位于超导磁体内部的电阻磁体产生的。高电感超导磁体与电阻磁体的连接通过减小时间纹波大大改善了磁场质量。由于降低了功耗，可以显著降低运行成本，并可以实现更长时间的连续运行。这将导致科学生产力的提高。SCH的独特特点为科学界带来了许多优势。较长的运行时间允许在高字段处进行较长的数据采集。更大的场稳定性降低了噪音，提高了大多数实验的灵敏度。较高的场提高了共振和成像的分辨率和对比度。磁体将主要用作表征材料特性和磁共振成像的工具。在凝聚态物理领域，将测量材料的电子、磁性、光学和超导性质。在化学方面，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。同样在生物学研究中，膜蛋白结构将被确定，研究将使用高分辨率磁共振显微镜进行。该SCH项目将包括来自佛罗里达州立大学/佛罗里达农工大学联合工程学院（FSU/FAMU CoE）以及这些机构和其他机构的物理系和化学系的本科生和研究生。FAMU是一个HBCU。

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.
