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

* 9704131吴 这个小企业创新研究第二阶段项目是开发一个原型600兆赫宽孔（89毫米）高分辨率核磁共振磁铁与内部锡超导导线。 这一方法的可行性已在第一阶段得到充分证明。 通过用内部锡丝代替铜丝，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立，测试和评估拟议的全尺寸原型核磁共振磁铁。 为了实现这些目标，Cryomagnetics，Inc.提出了一种技术方法，包括在持久模式下分别测试每个NbTi和Nb 3Sn线圈的稳定性，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，将开发和全面测试全尺寸原型600 MHz宽口径高分辨率NMR磁体。 这种原型磁体将成为第三阶段计划的卖点--600 MHz宽口径高分辨率NMR磁体的商业化。 第一阶段和第二阶段开发的新技术将通过降低NMR系统成本产生巨大的商业影响。 所提出的宽口径核磁共振磁体系统将是理想的显微成像和体内光谱以及生物固态核磁共振光谱。 该项目第二阶段的成功完成将使市场上出现廉价、宽口径、高场核磁共振磁体。 ***

*** 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. ***
