Intellectual Merit :In this project a new fully optical CE-FRS detection scheme is proposed to mitigate needsfor any chemical treatments of the sample gas that is usually required with currently availableinstrumentation for trace oxygen sensing. The project will leverage unique capabilities ofdevelopment and commercialization of cavity enhanced technologies by Tiger Optics and thenew sensing technology based on FRS developed and demonstrated by MIRTHE. Initially a proof-of-conceptprototype system will be investigated based on a conventional two mirror high-Finesse cavityequipped with a custom FRS optics for signal extraction. Most importantly the proposed researchwill also explore the possibility of implementing CE-FRS using the Tiger Optics proprietaryhigh-Finesse optical prism cavity technology. This unique technology would allow CE-FRS tobe implemented in combination with standard cw-CRDS in the same commercial instrument, permittingsensitive broadband detection of paramagnetic and diamagnetic molecules simultaneously. Theproposed technology will eliminate routine maintenance issues, chemical conversion uncertaintyand other disadvantages typical for electrochemical systems or indirect sensing technologies.The proposed direct laser-based detection provides significant advantage in industrial applicationswhere 24-7 continuous monitoring is required and in environmental applications where analyzersare often situated in remote locations with basic infrastructure.Broader Impacts :Development of a CE-FRS method will open up possibilities for sensitive monitoring of manyother paramagnetic species. This method will be suitable for real-time monitoring of traceconcentrations of radicals involved in combustion and atmospheric chemistry, i.e. NO, NO2,OH, HO2, and CH. In many cases, while the presence of these radicals is known, the reactionrates and abundances are not well known due to the lack of in situ monitoring capabilities.A direct laser-based method can provide a new tool for monitoring trace-radicals in a widerange of applications such as environmental monitoring, industrial process control or combustiondiagnostics. Therefore scientific and engineering advancements in this field integrated witha comprehensive educational program addressing specific career development goals at each academiclevel from high school students to post-doctoral researchers, will provide an excellent trainingfor the new generation

智力优点：在这个项目中，提出了一种新的全光学CE-FRS检测方案，以减轻对样品气体的任何化学处理的需求，这种化学处理通常需要使用目前可用的痕量氧传感仪器。该项目将利用Tiger Optics开发和商业化腔增强技术的独特能力，以及MIRTHE开发和演示的基于FRS的新传感技术。最初的概念验证原型系统将进行调查的基础上，传统的两个镜子高精细度cavityequipped与定制FRS光学信号提取。最重要的是，拟议的研究还将探讨使用老虎光学专有的高精细光学棱镜腔技术实现CE-FRS的可能性.这种独特的技术将允许CE-FRS与标准cw-CRDS在同一商业仪器中结合使用，同时实现顺磁性和反磁性分子的灵敏宽带检测。所提出的技术将消除常规维护问题、化学转化不确定性以及电化学系统或间接传感技术的其他典型缺点。所提出的直接基于激光的检测在需要24-7连续监测的工业应用中以及在分析仪通常位于具有基本基础设施的偏远位置的环境应用中提供了显著优势。CE-FRS方法的发展将为许多其他顺磁性物质的灵敏监测开辟可能性。这种方法将适用于实时监测燃烧和大气化学中涉及的自由基的痕量浓度，即NO、NO2、OH、HO 2和CH。在许多情况下，虽然这些自由基的存在是已知的，由于缺乏现场监测能力，反应速率和丰度还不是很清楚，基于直接激光的方法可以提供一种新的监测痕量的工具，在环境监测、工业过程控制或燃烧诊断等广泛的应用中，因此，该领域的科学和工程进步与全面的教育计划相结合，解决从高中生到博士后研究人员的每个学术水平的具体职业发展目标，将为新一代提供出色的培训
