这项授予伊利诺伊大学芝加哥分校的重大研究仪器奖支持购买和实施最先进的碲化镉(CdTe)像素阵列面阵探测器，用于化学、材料和地球科学领域的先进X射线同步加速器应用。这些仪器将支持先进光子源化学和土壤环境研究中心(阿贡国家实验室)的研究。ChemMatCARS和GSECARS是国家用户设施，对国家的研究和教育基础设施具有广泛影响，每年为约1400名用户提供服务。使用这种探测器对材料的研究将为我们在原子水平上对材料的科学理解提供基础。该探测器特别适用于先进光子源的高能X射线源。这些研究人员中有一半以上是学生，他们接受过最先进的X射线技术培训。ChemMatCARS和GSECARS举办讲习班和其他培训，包括重点培训妇女和代表性不足的少数族裔学生。培训下一代科学家使用拟议的最先进的探测器使我们的科学界保持最新，并为他们提供最好地解决其研究中具有挑战性的问题所需的实验工具。除了材料研究部和地球科学部的主要研究仪器基金外，该奖项还得到了化学部和数学和物理科学局多学科活动办公室的资助。X射线探测器用于记录X射线与材料的相互作用，从而得出材料的原子级结构。新型探测器Pilatus3X CdTe 1M的性能，包括其大的有效面积、高能下的高效率、速度、大动态范围和低噪声光子计数，将改变ChemMatCARS和GSECARS的结晶学和其他测量方法。在ChemMatCARS内部，该探测器将主要由先进的结晶学站在研究领域使用，包括太阳能转换、光激发、催化、硬无机材料、金属-金属结合络合物以及金属有机框架内的工艺。在GSECARS中，新的探测器将用于研究，以促进对地球材料的组成、结构和性质的了解，以及产生它们的过程和它们控制的过程。GSECARS的独特能力将继续使其能够在研究领域进行开创性实验，这些研究领域包括钻石顶压机和多顶压机中的高压和高温矿物物理、高压和高温下的非晶体和纳米晶体材料，包括在模拟地球深部地幔条件下的液体研究，以及矿物-水界面反应。

This Major Research Instrumentation award to the University of Illinois at Chicago supports the acquisition and implementation of a state-of-the art cadmium telluride (CdTe) pixel array area detector for advanced X-ray synchrotron applications in the areas of chemical, materials, and earth sciences. The instruments will support research at ChemMatCARS and GeoSoilEnviroCARS (GSECARS) the Advanced Photon Source (Argonne National Laboratory). ChemMatCARS and GSECARS are national user facilities with a broad impact on the nation's research and educational infrastructure and serve about 1400 users annually. Studies of materials using this detector will provide the foundation for our scientific understanding of materials at the atomic level. This detector is particularly well suited to the high energy X-ray source at the Advanced Photon Source. Over half of these researchers are students, who are trained in state-of-the-art X-ray techniques. ChemMatCARS and GSECARS conduct workshops and other training, including a focus on training and outreach for women and under-represented minority students. Training the next generation of scientists in the use of the proposed state-of-the-art detector keeps our scientific community up to date and provides them with the experimental tools needed to best address the challenging problems in their research. In addition to Major Research Instrumentation funds from the Division of Materials Research and the Division of Earth Sciences, this award is supported using funds from the Chemistry Division and The Office of Multidisciplinary Activities in the Mathematical and Physical Sciences Directorate.X-ray detectors are used to record the interaction of X-rays with materials, thus yielding the atomic-level structure of the material. The capabilities of the new detector, the Pilatus3 X CdTe 1M, which include its large active area, high efficiency at high energies, speed, large dynamic range, and low-noise photon counting, will transform crystallography and other measurements at ChemMatCARS and GSECARS. Within ChemMatCARS, the detector will be used primarily by the advanced crystallography station in research areas that include solar energy conversion, photo-excitation, catalysis, hard inorganic materials, metal-metal bonded complexes, and processes within metal organic frameworks. Within GSECARS, the new detector will be used in research to advance knowledge of the composition, structure and properties of earth materials, the processes that produce them and the processes they control. The unique capabilities of GSECARS will continue to allow groundbreaking experiments to be conducted in research areas that include high pressure and high temperature mineral physics in the diamond anvil cell and multi-anvil press, non-crystalline and nano-crystalline materials at high pressure and high temperature, including studies of liquids at conditions that simulate the Earth's deep mantle, and mineral-water interface reactions.
