This project will continue to operate, develop, and improve the Cornell High Energy Synchrotron Source (CHESS) over the five-year period 1 April 2003 through 31 March 2008. CHESS is a unique national synchrotron radiation user facility that operates parasitically on the Cornell Electron Storage Ring (CESR), producing high energy X-rays from the 5 - 8 GeV electrons and positrons in the ring. Since 1998, CHESS has hosted 2516 visits from investigators from all over the world to conduct research in a wide range of science and engineering disciplines in academia, industry, and government. For example, CHESS has been used for investigations of the atomic structure, properties, and time-resolved behavior of electronic, structural, polymeric, and biological materials, protein and virus crystallography, environmental science, radiography of solids and fluids, and microelemental analyses. CHESS is an incubator of new synchrotron science, people, methods, and instrumentation. To date, 449 students have received Ph.D. degrees using data taken at CHESS. In consequence, CHESS is a national resource for new beamline scientists.X-rays are produced as byproducts from the acceleration of electrons to very high energies. This occurs in the Cornell Electron Storage Ring (CESR), producing X-rays that are utilized by the Cornell High Energy Synchrotron Source (CHESS). This radiation can be used to determine the properties and time-resolved behavior of a wide range of electronic, structural, polymeric, and biological materials. In addition, the X-rays can be used to determine the structures of proteins and viruses, for environmental science, and to obtain radiographs of solids and fluids. Many of these pieces of information can be obtained in no other way. For example, time-resolved X-ray images of pressurized fuel sprays have been obtained that may lead to significant improvements in engine performance. This project will continue to operate, develop, and improve CHESS over the five-year period 1 April 2003 through 31 March 2008.

该项目将在2003年4月1日至2008年3月31日的五年期间继续运营、开发和改进康奈尔高能同步加速器源（CHESS）。CHESS是一个独特的国家同步加速器辐射用户设施，寄生在康奈尔电子上运行存储环 (CESR)，从环中的 5 - 8 GeV 电子和正电子产生高能 X 射线。 自 1998 年以来，CHESS 已接待了来自世界各地的 2516 名研究人员来访，在学术界、工业界和政府的广泛科学和工程学科领域开展研究。 例如，CHESS 已用于研究电子、结构、聚合物和生物材料的原子结构、性质和时间分辨行为、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量元素分析。 CHESS 是新同步加速器科学、人员、方法和仪器的孵化器。 迄今为止，已有 449 名学生获得博士学位。使用 CHESS 采集的数据获得学位。 因此，CHESS 是新束线科学家的国家资源。X 射线是电子加速到极高能量时产生的副产品。 这种情况发生在康奈尔电子存储环 (CESR) 中，产生由康奈尔高能同步加速器源 (CHESS) 使用的 X 射线。这种辐射可用于确定各种电子、结构、聚合物和生物材料的特性和时间分辨行为。 此外，X 射线还可用于确定蛋白质和病毒的结构、用于环境科学以及获取固体和液体的射线照片。 其中许多信息无法通过其他方式获得。 例如，已经获得了加压燃料喷雾的时间分辨X射线图像，这可能会导致发动机性能的显着改善。 该项目将在2003年4月1日至2008年3月31日的五年期间继续运营、开发和改进CHESS。CHESS是一个独特的国家同步辐射用户设施，接待了来自世界各地的研究人员来访进行研究学术界、工业界和政府的广泛科学和工程学科。 CHESS 是新同步加速器科学、人员、方法和仪器的重要孵化器。
