BULK HIGH TC SUPERCONDUCTOR FOR HIGH FIELD NMR INSERTS

这个小企业创新研究第一阶段项目将研究用于核磁共振插入件的高温超导技术。高温超导体在这种应用中的优势是可以获得更大的领域，而不是在高于4 K的温度下运行。这项技术将在第二阶段和第三阶段实施，以建立和验证这种仪器的研究应用。提出的研究评估现有的块状超导体管作为核磁共振插入。这项技术已经得到了验证，我们已经在20t的背景下测试了1t的插入物。该方案解决了产生的场均匀性问题，以便能够基于该概念设计出高场，高分辨率的核磁共振机。该项目将利用位于佛罗里达州塔拉哈西的国家高磁场实验室的设备。提议的商业应用：提议的方法可以提供一种廉价的方法，利用高温超导材料在高场核磁共振仪器中插入。此外，该技术可用于升级现有仪器。

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.
