IMR: Integrated Imaging System for Transmission Electron Microscope

该项目的目的是开发一种独特的应力控制流变仪，适用于同步加速器散射设施（例如国家同步加速器光源（NSLS），布鲁克海文国家实验室（BNL）的先进聚合物光束线，APB, (X27C)），并结合石溪的拉曼光谱。应力控制流变仪的改进，包括安装x射线路径、x射线窗口、光束监测装置、样品监测系统和光束瞄准的平移阶段，这将使原位散射/衍射研究成为可能，并对石溪的光纤拉曼光谱仪进行小的修改。该仪器是世界上同类同步加速器研究中的第一个。它将对聚合物和软材料社区参与尖端研究项目特别有用，例如聚合物熔体、嵌段共聚物、纳米复合材料、复杂流体、结构凝胶和生物系统中的流动诱导相变和分层结构变化。该项目的目的是开发一种独特的应力控制流变仪，适用于同步加速器散射设施（例如国家同步加速器光源（NSLS），布鲁克海文国家实验室（BNL）的先进聚合物光束线，APB, (X27C)），并结合石溪的拉曼光谱。X27C光束线于1997年由石溪大学和几个工业和政府实验室的一组科学家委托。X27C设施是美国第一个致力于化学/材料研究（重点是聚合物）的同步加速器光束线。它使用最先进的同步小角x射线散射（SAXS）和广角x射线衍射（WAXD）技术来表征材料的结构变化，长度范围从1到1000埃。该设施对材料界的主要好处是，普通用户进行尖端实验不需要广泛的同步加速器经验和设备准备。如今，X27C已成为美国聚合物界用于时间分辨和原位SAXS/WAXD研究的主要工具。在过去六年中，来自100多个用户组（即70多个研究机构）的350多个用户对这些光束线进行了实验。因此，我们设想这种独特的仪器不仅将提供发现材料基本现象的新能力，而且还将为缺乏x射线和/或流变学经验的学生，科学家和工程师提供新的教育机会。

The purpose of this project is to develop a unique stress-controlled rheometer to be adapted in the synchrotron scattering facility (e.g. Advanced Polymers Beamline, APB, (X27C) at the National Synchrotron Light Source (NSLS), Brookhaven National Laboratory (BNL)) and in combination with Raman spectroscopy at Stony Brook. The modifications of the stress-controlled rheometer, including the installation of x-ray paths, x-ray windows, beam monitoring device, sample monitoring system and translational stages for beam targeting, which will enable in-situ scattering/diffraction studies, and minor modifications for adaptation with the fiber optic Raman Spectrometer at Stony Brook. The proposed instrumentation is the first of its kind for synchrotron research in the world. It will be particularly useful for the polymers and soft materials communities to engage cutting-edge research projects, such as flow-induced phase transitions and hierarchical structural changes in polymer melts, block copolymers, nanocomposites, complex fluids, structured gels and biological systems.The purpose of this project is to develop a unique stress-controlled rheometer to be adapted in the synchrotron scattering facility (e.g. Advanced Polymers Beamline, APB, (X27C) at the National Synchrotron Light Source (NSLS), Brookhaven National Laboratory (BNL)) and in combination with Raman spectroscopy at Stony Brook. The X27C beamline was commissioned in 1997 by a group of scientists from Stony Brook University and several industrial and government laboratories. The X27C facility is the first synchrotron beamline in the United States dedicated to chemistry/materials research (with emphasis on polymers). It uses state-of-the-art simultaneous small-angle x-ray scattering (SAXS) and wide-angle x-ray diffraction (WAXD) techniques to characterize structural changes of materials with length scales from 1 to 1000 Angstroms. The major benefit of this facility to the materials community is that no extensive synchrotron experience and equipment preparation are required from general users to carry out cutting-edge experiments. Today, X27C has become a major workhorse serving the U.S. polymer community for time-resolved and in-situ SAXS/WAXD studies. More than 350 users from over 100 user groups (i.e. over 70 research institutes) have carried out experiments at these beamlines in the past six years. Thus, we envision that this unique instrument will not only provide new capability to discover fundamental phenomena in materials, but will also provide new education opportunities to students, scientists and engineers with little x-ray and/or rheological experiences.
