Bent Laue Analyzer for X-ray Fluorescence Spectroscopy

我们发明了一种新型的弯劳埃x射线分析仪系统，为稀金属蛋白、生物材料和生物工程研究以及环境科学的x射线吸收光谱和x射线微探针研究提供了独特的能力。这种探测器概念在XAFS社区中引起了极大的兴趣，如果以适当的方式商业化，显然会有很大的需求。该探测器系统的性能在能量分辨率、最大计数率和时间响应方面预期是异常的，并且最终用户的成本可能是非常合理的。该提案的目标是确定最佳设计，并在比以前尝试的更低的能量范围内构建和测试这类新的探测器。如果成功的话，这些装置将以合理的成本向实验者和同步加速器设施提供商业化。虽然这种类型的设备已成功地在高能量（20千电子伏及以上）进行了测试，我们打算开发最佳的设计范围从4千电子伏至15千电子伏，并探索替代方法的制造和成型的极薄的晶体，需要在低能量。通过二维弯曲和构造多单元阵列来最大化吞吐量的方法也将被研究。拟议的商业应用：此类设备具有巨大的潜在商业影响，为X射线光谱学界提供服务。近期收入估计在500万美元范围内。二次影响将更加重要，因为这代表了生物医学科学，生物工程，材料研究，化学，物理学和环境科学的一种使能技术。

We have invented a novel class of bent laue x-ray analyzer systems that offer unique capabilities for x-ray absorption spectroscopic and x-ray microprobe studies of dilute metalloproteins, biomaterials and bioengineering research, and environmental sciences. This detector concept has been received with great interest in the XAFS community and it is clear there would be significant demand if commercialized in an appropriate manner. Performance of this detector systems is expected to be exceptional in regard to energy resolution, maximum count rate, and time response, and the cost to the end user could be very reasonable. The goal of this proposal is to determine optimal designs, and to constructs and test this new class of detectors in a lower energy range than previously attempted. If successful, the devices will be made available commercially at reasonable cost to experimenters and synchrotron facilities. Although devices of this type have been successfully tested at high energies (20 KeV and above), we intend to develop optimal designs in the range from 4 KeV to 15 KeV, and also to explore alternative methods of fabrication and shaping the extremely thin crystals that are needed at low energies. Methods of maximizing throughput by two- dimensional bending and construction of multi-element arrays also will e investigated. PROPOSED COMMERCIAL APPLICATIONS: This class of devices has substantial potential commercial impact serving the x-ray spectroscopy community. Near-term revenue estimates are in the $5M range. Secondary impact will be even more important because this represents an enabling technology for biomedical sciences, bioengineering, materials research, chemistry, physics, and environmental sciences.
