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

北伊利诺伊大学化学系将与伊利诺伊大学和芝加哥大学的同事一起获得高亮度X射线光学元件，以升级位于阿贡国家实验室高级光子源的ChemMatCARS同步加速器X射线用户设施，并获得主要研究仪器(MRI)计划的这一奖项。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，并使目前无法进行的实验成为可能。该用户设备为研究从原子到介观的长度尺度上的液体和固体的表面、界面和整体性质提供了独特的高亮度X射线资源。由ChemMatCARS用户设施促成的研究活动开创了采用同步加速器技术以最好地为化学界服务的步伐；促进了改进材料的开发，特别是塑料、薄膜和纳米复合材料；作为各级研究人员的培训基地；并将同步加速器用户群体扩大到考古学、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.
