SBIR PHASE II: The Development of a 600 MHz Wide Bore (89 mm) High Resolution NMR Magnet with Internal Tin Wires

*9704131吴这个小型企业创新研究第二阶段项目是开发一种600 MHz宽口径(89 Mm)高分辨率核磁共振磁体的原型，内部为锡超导导线。这种方法的可行性在一期工程中得到了充分的验证，通过将青铜加工的导线更换为内部锡丝，将显著降低高场核磁共振系统的成本。第二阶段的研究目标是建造、测试和评估拟议的全尺寸核磁共振磁体原型。为了实现这些目标，低温磁学公司提出了一种技术方法，包括分别测试每个NbTi和Nb3Sn线圈在持续模式下的稳定性，以确保每个线圈的性能，然后组装线圈并测试磁体。在第二阶段研究结束时，将开发一台600 MHz大口径高分辨率核磁共振磁体的全尺寸原型，并进行全面测试。这种原型磁铁将成为第三阶段计划的卖点--600兆赫大口径高分辨率核磁共振磁铁的商业化。第一阶段和第二阶段开发的新技术将通过降低核磁共振系统成本产生巨大的商业影响。建议的大口径核磁共振磁体系统将是显微成像和活体光谱以及生物固态核磁共振光谱的理想选择。该项目第二阶段的成功完成将使市场上出现价格低廉、大口径、高场强的核磁共振磁体。***

*** 9704131 Wu This Small Business Innovation Research Phase II project is to develop a prototype 600MHz wide bore (89mm) high resolution NMR magnet with internal tin superconducting wires. The feasibility of this approach has been fully proven in Phase I. Through replacement of bronze-processed wire by internal tin wire, high field NMR system cost will be reduced significantly. The Phase II research objective is to build, test and evaluate the proposed full scale prototype NMR magnet. To achieve the objectives, Cryomagnetics, Inc. proposes a technical approach consisting of testing stability of each NbTi and Nb3Sn coil separately under persistent mode operation to insure each coil's performance, and then assembling coils and testing the magnet. At the end of Phase II research, a full scale prototype 600 MHz wide bore high resolution NMR magnet will be developed and fully tested. This prototype magnet will be the selling point for the Phase III program--the commercialization of 600 MHz wide bore high resolution NMR magnets. The new technologies developed in Phase I and II will generate great commercial impact by reducing NMR system cost. The proposed wide bore NMR magnet system will be ideal for micro-imaging and in vivo spectroscopy as well as biological solid state NMR spectroscopy. The successful completion of Phase II of this project will make inexpensive, wide bore, high field NMR magnets available in the market. ***
