*** 9761221 Withers This Small Business Innovation Research Phase 1 project will produce a detailed design of a high-temperature-superconductive (HTS) nuclear-magnetic-resonance spectroscopy (NMRS) probe for operation in a 21-T (900-MHz) magnet. High-sensitivity probes have recently been commercially introduced at proton frequencies of 400, 500, and 600 MHz. The highest specified proton sensitivity is the 3000:1 of the 600-MHz probe. The probe designed during Phase 1 will be built during Phase 2 and evaluated in the 21-T magnet at the National High Magnetic Field Laboratory in Tallahassee, FL. This probe will have a proton sensitivity of 6000:1, twice that now available. In Phase 1, RF test coils will be fabricated, ready for in-field characterization as soon as a high-field magnet is available. This will be the highest field at which RF properties of HTS materials have been measured. Approximately 1500 high-resolution NMRS probes are sold per year. High-sensitivity superconductive probes are expected to reach 20% of this unit volume. At an end-user price of $80,000 per unit, this is a $24,000,000 market. Extension of this product line to the highest available field strengths will provide the ultimate in NMR sensitivity. ***

* 9761221威瑟斯 这个小型企业创新研究第一阶段项目将产生一个高温超导（HTS）核磁共振光谱（NMRS）探头的详细设计，用于在21 T（900 MHz）磁体中运行。 高灵敏度探针最近已经在商业上引入了400、500和600 MHz的质子频率。 最高的质子灵敏度是600 MHz探头的3000：1。 在第一阶段设计的探头将在第二阶段建造，并在佛罗里达州塔拉哈西的国家高磁场实验室的21 T磁体中进行评估。该探头的质子灵敏度为6000：1，是现在的两倍。 在第1阶段，将制造RF测试线圈，一旦高场磁体可用，即可进行场内表征。 这将是测量高温超导材料射频特性的最高场。 每年大约销售1500个高分辨率NMRS探头。 高灵敏度的MEMS探头预计将达到该单位体积的20%。以每单位8万美元的最终用户价格计算，这是一个2400万美元的市场。 将该产品线扩展到最高可用场强将提供最终的NMR灵敏度。 ***
