化学研究仪器和设施计划在化学司，材料研究司和基础能源科学办公室在能源部提供持续支持ChemMatCARS在阿贡先进光子源。该奖项提供了维护，操作和选择性升级这一独特的资源作为化学和材料科学界的国家用户设施。该设施支持的技术包括静态和时间分辨X射线衍射、表面敏感和界面X射线散射、小角度X射线散射和广角X射线散射。 该仪器可适应各种不同的用户腔室，用于特殊的样品环境。该用户设备提供独特的高亮度X射线源，用于研究液体和固体的表面、界面和体积性质，长度范围从原子到介观。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 Research Instrumentation and Facilities Program in the Chemistry Division, the Division of Materials Research and the Office of Basic Energy Sciences at the Department of Energy provide continuing support to ChemMatCARS at the Argonne Advanced Photon Source. This award provides maintenance, operation and selected upgrades of this unique resource as a national user facility for the chemical and materials science community. Techniques supported by the facility include static and time-resolved x-ray diffraction, surface-sensitive and interface x-ray scattering, small-angle x-ray scattering and wide-angle x-ray scattering. The instrumentation can be adapted to accept a wide variety of user chambers for specialized sample environments.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.
