BULK HIGH TC SUPERCONDUCTOR FOR HIGH FIELD NMR INSERTS

这个小型企业创新研究第一阶段项目将研究用于NMR插入的高温超导技术。高温超导体在这一应用中的优势是可以实现更大的磁场，而不是在远高于4 K的温度下工作。这项技术将在第二阶段和第三阶段实施，以建造和鉴定这种仪器用于研究应用。拟议的研究评估现有的大块超导体管插入核磁共振。该技术已得到证实，我们已在20 T背景下测试了1 T插入物。该建议解决了所产生的场均匀性的问题，以便能够基于该概念设计高场、高分辨率NMR机器。该计划将利用位于弗拉塔拉哈西的国家高磁场实验室的设施。拟议的商业应用：所提出的方法可以提供一种利用高温超导材料用于高场NMR仪器中的插入件的廉价方法。此外，该技术还可用于现有仪器的升级换代。

This Small Business Innovation Research Phase I Project will investigate a high temperature superconducting technology for use in NMR inserts. The advantage of the high temperature superconductor for this application is the possibility of achieving substantially greater fields, rather than the operation at temperatures substantially higher than 4 K This technology will be implemented in Phase II and Phase III to build and qualify such an instrument for research applications. The proposed research evaluates existing bulk superconductor tubes as inserts for NMR. The technology has been proven and we have tested a l T insert in a 20 T background. This proposal addresses the issues of resulting field homogeneity in order to be able to design a high field, high resolution NMR machine based upon the concept. The program will take advantage of the facilities at the National High Magnetic Field Laboratory in Tallahasee, Fla. PROPOSED COMMERCIAL APPLICATIONS: The proposed method may provide an inexpensive method of utilizing high temperature superconducting material for inserts in high-field NMR instruments. Additional, the technology could be used to upgrade present instruments.
