Non-technical AbstractThis award from the National Science Foundation to Cornell University supports the operation of the Cornell High Energy Synchrotron Source (CHESS) as a national user facility. User access is granted free of charge through a competitive proposal review process. CHESS provides high energy X-ray beams, for studies including the atomic and nanoscale structure, properties, in operando, and time-resolved behavior of electronic, structural, polymeric and biological materials, protein and virus crystallography, environmental science, radiography of solids and fluids, and micro-elemental analysis. The synchrotron facility is used by investigators from a wide range of science and engineering disciplines in academia, industry, government, non-profits, and international institutions. CHESS attracts new users through presenations at professional society meetings, a monthly newsletter, and their website. This award also provides support to upgrade the facility and enhance the capabilities of the existing instruments. These upgrades enable CHESS to increase the number users and provide unique capabilities to the research community. Technology development at CHESS on new X-ray extraction devices, detectors, and optics will advance synchrotron science. CHESS plays a national role in advanced training of X-ray beamline scientists, expert X-ray users; and accelerator scientists. CHESS educates the K-12 students and teachers, community college students, and the public through science activities, after-school science programs, and tours. CHESS has specific initiatives aimed at increasing participation of underrepresented groups in Science Technology Education and Mathematics (STEM) fields with goals of improving science literacy and the national workforce. Technical AbstractThis award from the National Science Foundation to Cornell University supports the operation of the Cornell High Energy Synchrotron Source (CHESS) as a national user facility for a five year period to advance materials science, condensed matter physics, chemistry, engineering, and biology through advanced uses of X-ray radiation. CHESS will deliver 140 user days per year to 11 beamlines that enable advanced imaging, the determination of atomic and larger scale structure in materials, and various spectroscopies to probe electronic organization and transitions in materials. User access is granted free of charge through a competitive external proposal review process. CHESS will pursue the following seven collaborative user initiatives, which are expected to drive their respective scientific fields and will guide beamline upgrades: Computationally-Enabled Total Scattering Studies of Complex Materials; Designer Solids: Structure, Processing and Performance; Rapidly Evolving Systems; X-Ray Imaging: Scanning Probe and Full-Field; Spectroscopic Studies; Energy and Structural Materials: In Operando Studies; and, Macromolecules and Biochemistry. This award also provides support for upgrades of the facility, most notably the installation of three Cornell designed undulators, which are an order of magnitude less expensive than current technology. The increased flux from the undulators at 7 of the 11 beamlines will enable new experiments at CHESS such as probing the structure of excited electronic states.CHESS plays a national role in advanced training of X-ray beamline scientists, expert X-ray users; and accelerator scientists. The Xraise program reaches out to K-12, community college students and public school teachers. Xraise collaborates with other Cornell research centers and local schools to offer classroom science activities, creates and sponsors after-school science programs, and hosts tours and demonstrations for the public in the eXploration Station. CHESS has specific initiatives aimed at increasing participation of underrepresented groups in Science Technology Education and Mathematics (STEM) fields with goals of improving science literacy and the national workforce.

非技术摘要这项来自国家科学基金会授予康奈尔大学的奖项支持康奈尔高能同步器源（国际象棋）作为国家用户设施的运作。 通过竞争提案审核过程免费授予用户访问。 国际象棋提供高能X射线束，用于研究，包括原子和纳米级结构，在操作中的特性，以及电子，结构，聚合物和生物学材料，蛋白质和病毒晶体学，环境科学，固体和流体的射线照相，以及微元素元素分析的时间分辨行为。 同步设施由学术界，工业，政府，非营利组织和国际机构的各种科学和工程学科的研究人员使用。 国际象棋通过在专业协会会议，每月新闻通讯及其网站上的培训来吸引新用户。 该奖项还提供了支持，以升级设施并增强现有工具的功能。 这些升级使国际象棋能够增加用户的数量，并为研究社区提供独特的功能。 新的X射线提取设备，探测器和光学的技术开发将推进同步器科学。 国际象棋在X射线光束线科学家，专家X射线用户的高级培训中扮演国家角色；和加速器科学家。 国际象棋通过科学活动，课后科学课程和巡回演出来教育K-12的学生和老师，社区大学生和公众。 国际象棋旨在提高代表性不足的科学技术教育和数学（STEM）领域的参与，其目标是改善科学素养和国家劳动力。 康奈尔大学国家科学基金会（National Science Foundation）的技术摘要奖支持康奈尔高能同步器（CHESS）作为国家用户设施的运作，该奖项在五年内通过X射线辐射的先进用途推进了材料科学，凝结物理学，化学，工程，工程和生物学。 国际象棋每年将提供140个用户天，以实现高级成像，材料中原子和较大规模结构的确定以及各种光谱镜的确定，以探测材料中的电子组织和过渡。 通过竞争性的外部提案审查过程免费授予用户访问。 国际象棋将追求以下七个协作用户计划，这些计划有望推动其各自的科学领域，并将指导光束线的升级：基于计算的复杂材料的总散射研究；设计师固体：结构，处理和性能； 快速发展的系统； X射线成像：扫描探针和全场；光谱研究；能源和结构材料：在操作研究中；以及大分子和生物化学。 该奖项还为设施的升级提供了支持，最值得注意的是，安装了三个康奈尔（Cornell）设计的不输出器，这比当前技术便宜。 11个梁线中有7个波动器的通量增加将使在国际象棋上进行新的实验，例如探测激发电子状态的结构。和加速器科学家。 Xraise计划与K-12，社区大学生和公立学校老师联系。 Xraise与其他康奈尔大学研究中心和当地学校合作，提供课堂科学活动，创建和赞助商的课后科学计划，并在勘探站举办公众的旅行和示威活动。 国际象棋旨在提高代表性不足的科学技术教育和数学（STEM）领域的参与，其目标是改善科学素养和国家劳动力。
