Operation of the Cornell High Energy Synchrotron Radiation Laboratory (CHESS)

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行、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辐射用户设施，寄生在康奈尔电子存储环(CESR)上运行，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，国际象棋已经接待了来自世界各地的2516名研究人员，在学术界、工业界和政府的广泛科学和工程学科中进行研究。例如，CHESS已被用于研究电子、结构、聚合物和生物材料的原子结构、性质和时间分辨行为，蛋白质和病毒结晶学，环境科学，固体和流体的射线照相，以及微量元素分析。国际象棋是新的同步加速器科学、人、方法和仪器的孵化器。到目前为止，已有449名学生使用国际象棋上的数据获得了博士学位。因此，国际象棋对于新的光束线科学家来说是一个全国性的资源。X射线是电子加速到非常高能量的副产品。这发生在康奈尔电子存储环(CESR)，产生的X射线被康奈尔高能同步加速器源(CHESS)利用。这种辐射可以用来确定各种电子、结构、聚合物和生物材料的性质和时间分辨行为。此外，X射线可以用来确定蛋白质和病毒的结构，用于环境科学，并获得固体和液体的射线照片。这些信息中的许多都是无法通过其他方式获得的。例如，已经获得了加压燃料喷雾的时间分辨率X射线图像，这可能会导致发动机性能的显著改善。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、发展和改进国际象棋。CHESS是一个独特的国家同步辐射用户设施，它接待了来自世界各地的研究人员访问，在学术界、工业界和政府的广泛科学和工程学科中进行研究。国际象棋是新的同步加速器科学、人、方法和仪器的重要孵化器。

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.
