项目摘要

The Synchrotron Radiation Center (SRC) operated by the University of Wisconsin-Madison, is a national facility for the utilization of ultra-violet and soft x-ray synchrotron radiation in scientific investigations. The studies carried out at the SRC impact condensed matter physics, atomic and molecular physics, chemistry, materials science and engineering, biology, and other disciplines. The SRC is a user oriented facility which accepts proposals from all qualified investigators. At present, more than 300 individuals make up 75 groups which conduct research on the 26 operating beamlines at the SRC. Of these groups, 69% are from universities, 19% are from national laboratories, and 12% are industrial affiliates. The SRC operation includes nine public beamlines, sixteen Participating Research Team (PRT) beamlines, one joint SRC/PRT beam line, and three beamlines under development. Eighteen operating lines have monochromators. They cover the photon energy range from a few eV to several keV. The SRC operates at two electron energies: 800 MeV and 1 GeV. A clean room and a chemical handling room are maintained for users. Several unique beamlines are available including five beamlines operated by the Center for X-ray Lithography, a beam line developed for high resolution photoemission x-ray microscopy utilizing an undulator (Multiple Application X-ray Imaging Undulator Microscope-MAXIMUM), a high resolution photoelectron spectroscopy beam line being developed for band-structure measurements of Fermi- surface contours in high-Tc superconducting materials, a high precision soft x-ray double-crystal monochromator beam line which provides a tunable beam in the 1500-3700 Ev range for Extended X-ray Absorption Fine Structure studies (EXAFS).

同步辐射中心（SRC）由威斯康星大学麦迪逊分校运营，是一个利用紫外线和软x射线同步辐射进行科学研究的国家设施。在SRC进行的研究影响凝聚态物理、原子和分子物理、化学、材料科学与工程、生物学和其他学科。SRC是一个面向用户的设施，接受所有合格研究人员的建议。目前，超过300人组成75个小组，对SRC的26条操作光束线进行研究。在这些团体中，69%来自大学，19%来自国家实验室，12%来自工业附属机构。SRC系统包括9条公共波束线、16条参与研究小组（PRT）波束线、1条SRC/PRT联合波束线和3条正在开发的波束线。18条操作线有单色仪。它们涵盖了光子能量范围从几个电子伏特到几个电子伏特。SRC在两种电子能量下工作：800 MeV和1 GeV。为使用者提供洁净室和化学品处理室。几个独特的光束线是可用的，包括五个由x射线光刻中心操作的光束线，一个为高分辨率光电发射x射线显微镜开发的光束线，利用一个波动器（多应用x射线成像波动器显微镜- maximum），用于高tc超导材料费米表面轮廓带结构测量的高分辨率光电子能谱束线；高精度软x射线双晶单色仪光束线，提供1500-3700 Ev范围的可调光束，用于扩展x射线吸收精细结构研究（EXAFS）。
