MRI: Acquisition of High Brilliance X-ray Optical Components for the ChemMatCARS Synchrotron X-ray Resource at the Advanced Photon Source

化学系在北方伊利诺伊大学与同事从伊利诺伊大学和芝加哥大学将获得高亮度X射线光学元件升级ChemMatCARS同步加速器X射线用户设施在先进的光子源，阿贡国家实验室与此奖项从主要研究仪器（MRI）计划。 这一升级将增加亮度和光束相干性，并将能量范围从30 keV扩展到40 keV。这将扩展目前测量的能力，并实现目前无法实现的实验。该用户设施提供独特的高亮度X射线资源，用于研究从原子到介观长度尺度上液体和固体的表面、界面和体积性质。ChemMatCARS用户设施所开展的研究活动为调整同步加速器技术以最好地服务于化学界设定了步伐;有助于改进材料的开发，特别是塑料，膜和纳米复合材料;作为各级研究人员的培训基地;并将同步加速器用户社区扩展到考古学，人类学和法医学。

The Chemistry Department at Northern Illinois University in conjunction with colleagues from the University of Illinois and the University of Chicago will acquire high brilliance X-ray optical components to upgrade the ChemMatCARS synchrotron x-ray user facility at the Advanced Photon Source, Argonne National Laboratory with this award from the Major Research Instrumentation (MRI) program. This upgrade should increase the brilliance and beam coherence and extend the energy range from 30 to 40 keV. This will expand the capabilities of present measurements and enable experiments that are currently not available.This user facility provides a unique high brilliance x-ray resource for the study of surface, interfacial and bulk properties of liquids and solids on length scales ranging from the atomic to the mesoscopic. The research activities enabled by the ChemMatCARS user facility set the pace in adapting synchrotron techniques to best serve the chemistry community; contribute to the development of improved materials, notably plastics, membranes and nano-composites; serve as a training ground for researchers at all levels; and expand the synchrotron user community into archeology, anthropology and forensics.
