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，用于同步加速器散射设施（例如布鲁克海文国家实验室（BNL）国家同步加速器光源（NSLS）的Advanced Polymers Beamline，APB，（X27 C）），并与斯托尼布鲁克的拉曼光谱仪结合使用。应力控制流变仪的改造，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平移台，这将使现场散射/衍射研究成为可能，并对斯托尼布鲁克的光纤拉曼光谱仪进行微小改造。该仪器是世界上第一台用于同步加速器研究的仪器。这将是特别有用的聚合物和软材料社区从事尖端的研究项目，如流动诱导的相变和分层结构的变化，聚合物熔体，嵌段共聚物，纳米复合材料，复杂的流体，结构化凝胶和生物系统。本项目的目的是开发一种独特的应力控制流变仪，适用于同步辐射散射装置（例如，在布鲁克海文国家实验室（BNL）的国家同步加速器光源（NSLS）的Advanced Polymers Beamline，APB，（X27 C）），并与斯托尼布鲁克的拉曼光谱结合。X27 C光束线于1997年由来自斯托尼布鲁克大学和几个工业和政府实验室的科学家组成。X27 C设施是美国第一个专门用于化学/材料研究（重点是聚合物）的同步加速器光束线。它使用最先进的同时小角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，一般用户不需要广泛的同步加速器经验和设备准备来进行尖端实验。如今，X27 C已成为美国聚合物社区的主要主力，用于时间分辨和原位SAXS/WAXD研究。在过去六年，来自100多个用户组（即70多个研究机构）的350多个用户在这些光束线上进行了实验。因此，我们设想这种独特的仪器不仅将提供新的能力来发现材料中的基本现象，而且还将为学生，科学家和工程师提供新的教育机会，几乎没有X射线和/或流变学经验。

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.
