EXP-SA: Detection of Explosives using HTS Enhanced Quadrupole Resonance

0731224Schiano这项工作的目标是提高使用薄膜高温超导(HTS)谐振器的四极共振(QR)检测系统的性能。QR系统使用类似于金属探测器中的搜索线圈来检测和识别特定的氮化合物。智力优势：拟议的项目建立在杜邦赞助的开发高温超导QR探头的重大研究成果的基础上。预计下一代商用QR爆炸物探测系统将使用高温超导QR探头取代普通金属线圈，以提高探测性能。由于QR谱是一种新兴的材料无损评估(NDE)技术以及药物的结构和生物活性表征技术，因此拟议的研究具有超越爆炸物检测的应用范围。在QR光谱学中使用薄膜高温超导探头方面获得的经验也有望指导开发用于核磁共振光谱的高温超导探头。PI与一名具有磁共振成像(MRI)专业知识的生物工程教员一起发起了一项研究项目，以探索QR医学成像系统的潜力。广泛影响：PI是宾夕法尼亚州立大学园区校区生物工程系的兼职教员，并开发了磁共振工程的本科生和研究生课程，这些课程交叉列出了电气工程和生物工程课程。

0731224SchianoThe objective of this work is to enhance the performance of quadrupole resonance (QR) detection systems that use thin-film high-temperature superconducting (HTS) resonators. QR systems detect and discriminate specific nitrogen compounds using a search coil similar to those found in metal detectors. Intellectual Merit:The proposed project builds upon a significant research effort sponsored by DuPont to develop HTS QR probes. It is anticipated that the next generation of commercial QR explosive detection systems will employ HTS QR probes in lieu of normal metal coils to enhance detection performance. The proposed research has applications beyond explosives detection as QR spectroscopy is an emerging technology for the non-destruction evaluation (NDE) of materials and the characterization of the structure and biological activity of pharmaceuticals. Experience gained in the utilization of thin-film HTS probes in QR spectroscopy is also expected to guide the development of HTS probes for nuclear magnetic resonance spectroscopy. The PI has an initiated a research project with a bioengineering faculty member with expertise in magnetic resonance imaging (MRI) to investigate the potential for a QR medical imaging system.Broader Impacts:The PI is an adjunct faculty member in the Department of Bioengineering at the University Park Campus of Penn State, and has developed undergraduate and graduate courses in magnetic resonance engineering that are cross listed between the electrical engineering and bioengineering programs.
