This award from the Instrumentation for Materials Research-Major Instrumentation Projects program provides support to the National High Magnetic Field Laboratory (NHMFL) to undertake the conceptual and engineering design of a revolutionary magnet system called the Series-Connected Hybrid. The term Hybrid derives from using both resistive and superconducting technologies in the same magnet system, while Series-Connected refers to the fact that individual coils in the system will be powered electrically in series, a feature that both mitigates important magnet-design issues as well as offers significant performance advantages to scientists using the facility. This concept will allow substantially improved field quality relative to other powered systems while simultaneously allowing important reductions of both operating and total lifetime costs. Since the system will be designed to operate on a single unit of the NHMFL power system (typically two to four are used on other magnets), it will permit simultaneous service to multiple users as well as reduce the specific electricity demand. These attributes make the proposed system particularly attractive to areas of scientific research where experiments require exposure for long periods of time to very high-quality magnetic fields.This award from the Instrumentation for Materials Research - Major Instrumentation Project program supports the National High Magnetic Field Laboratory (NHMFL) to undertake the conceptual and engineering design of a revolutionary magnet system called the Series-Connected Hybrid. The term Hybrid relates that both superconducting technology (in the form of Nb3Sn-based cable-in-conduit conductor) and resistive technology (in the form of the "Florida Poly-Bitter" technology pioneered at the NHMFL) will be used in the same magnet system, while Series-Connected refers to the fact that individual coils in the system will be powered electrically in series, a feature that both mitigates important engineering issues related to normal, off-normal, and faulted operations as well as offers significant performance advantages related to magnetic field stability, field quality, and cost of operation. The 35Tesla design field of the Series-Connected Hybrid will exceed presently available all-superconducting fields by 63% and fields in existing all-resistive magnets with similar bore and uniformity by 40%. Compared to standard all-resistive or hybrid magnets, the Series-Connected Hybrid will offer nearly three orders of magnitude improvement in field uniformity. As a result, the Series-Connected Hybrid will enable experiments in condensed-matter physics, materials chemistry, spin physics, EMR, and solution-NMR spectroscopy to be conducted in a previously unexplored parameter space of field and uniformity. Since the system will be designed to operate on a single 10MW unit of the NHMFL power system (typically two to four are used on other magnets), it will permit simultaneous service to multiple users as well as reduce the specific electricity demand. The project will open doors to a new generation of high-field magnets that consume less power, cost less over their operating lifetime, and facilitate substantially more magnet time for users.

该奖项来自材料研究仪器-主要仪器项目计划，为国家高磁场实验室（NHMFL）提供支持，以承担称为串联混合的革命性磁体系统的概念和工程设计。 混合式一词源于在同一个磁体系统中使用电阻和超导技术，而串联连接是指系统中的各个线圈将串联供电，这一特性既缓解了重要的磁体设计问题，又为使用该设施的科学家提供了显着的性能优势。 这一概念将允许大大提高现场质量相对于其他动力系统，同时允许两个操作和总寿命成本的重要减少。 由于该系统将被设计为在NHMFL电力系统的单个单元上运行（通常在其他磁体上使用两到四个），因此它将允许同时为多个用户提供服务，并减少特定的电力需求。 这些特性使得该系统对需要长时间暴露在高质量磁场中的科学研究领域特别有吸引力。该奖项来自材料研究仪器-主要仪器项目计划，支持国家高磁场实验室（NHMFL）承担革命性磁体系统的概念和工程设计，称为串联混合。 “混合”一词涉及到超导技术（以Nb 3Sn基导管中电缆导体的形式）和电阻技术（以在NHMFL开创的“佛罗里达聚苦”技术的形式）将被用于相同的磁体系统中，而串联连接是指系统中的各个线圈将被串联供电的事实，该特征既减轻了与正常、非正常和故障操作相关的重要工程问题，又提供了与磁场稳定性、场质量和操作成本相关的显著性能优势。 串联混合动力的35特斯拉设计磁场将超过目前可用的全超导磁场63%，并超过现有的具有类似孔和均匀性的全电阻磁体的磁场40%。 与标准的全电阻或混合磁体相比，串联混合磁体将在磁场均匀性方面提供近三个数量级的改进。 因此，串联混合动力将使凝聚态物理，材料化学，自旋物理，EMR和溶液NMR光谱学的实验能够在以前未探索的场和均匀性参数空间中进行。 由于该系统将被设计为在NHMFL电力系统的单个10 MW机组上运行（通常在其他磁体上使用两到四个），因此它将允许同时为多个用户提供服务，并减少特定的电力需求。 该项目将为新一代高场磁体打开大门，这些磁体消耗更少的功率，在其使用寿命内成本更低，并为用户提供更多的磁体时间。
