Intrinsic Surface Electronic Properties and Dynamics of Molecular Reactions on Solids Involving a Synchrotron Radiation Beamline Development Project (Materials Research)

该项目将在布鲁克海文国家实验室的国家同步加速器光源（NSLS） U-16端口使用最先进的扩展范围蚱shopper （ERG）单色仪进行创新研究。来自康奈尔大学和桑迪亚国家实验室的科学家和工程师正在建造光束线设备，主要研究新材料的特性和开发。梁线设计、施工、安装部分完成。这里提供补充支持，以完成硬件安装并优化光学和真空仪器。这笔资金将专门用于完成仪器的研制，目的是在高分辨率光发射光谱、荧光体和表面EXAFS和NEXAFS、正常发射光电子衍射和光子激发金属解吸光谱等领域实现新的重要研究目标。以单晶、超薄膜和支撑分散固体形式存在的半导体和复合材料。在涉及反应和散射的表面上获取时间相关信息，利用NSLS-VUV设施的高通量源和时间结构特征将是特别感兴趣的。

A program to carry out innovative research studies -- will use a state-of-the-art extended range grasshopper (ERG) monochromator on port U-16 at the National Synchrotron Light Source (NSLS), Brookhaven National Laboratory. The beamline facility is being built and will be used by scientists and engineers from Cornell University and Sandia National Laboratories with a primary interest in the characterization and development of new materials. The design, construction and installation of the beamline are partially completed. Supplementary support is provided here to complete installation of the hardware and to optimize the optical and vacuum instrumentation. This support will be used exclusively for completion of the instrumentation with the objective of achieving new and significant research objectives in the areas of high resolution photoemission spectroscopy, fluorescence bulk and surface EXAFS and NEXAFS, normal emission photoelectron diffraction and photon- stimulated desorption spectroscopy on metallic, semiconductor and compound materials in the form of single crystals, ultrathin films and supported dispersed solids. Acquisition of time- dependent information on surfaces involving reaction and scattering, exploiting the high-flux source and time-structure characteristics of the NSLS-VUV facility will be of special interest.
