Synchrotron Radiation Center (SRC)

威斯康星大学麦迪逊分校的同步辐射中心（SRC）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。SRC开展的研究影响了许多学科，包括凝聚态物理、原子和分子物理、化学、材料科学与工程以及其他学科。SRC是一个面向用户的设施，接受所有合格研究人员的建议。它支持来自58所大学、国家和工业实验室的388个用户社区。目前有18条光束线正在运行，6条正在开发中，还有5条正在计划中。其中包括两条正在运行的专用光束线，一条正在开发中，另外两条分配给x射线光刻中心。一种以波动器为源的x射线显微镜正在建造中。在SRC进行的研究已被证明是非常富有成效的，最近的出版物相当于同期全球总数的15%。最近25篇关于高温超导体的论文表明了SRC及其用户对新发展的反应能力，第一篇论文于1987年4月提交。计划增加软x射线束线，并改进1 GeV存储环操作以适应更高的电流。环的改进将提供更多的高能辐射，这对x射线光刻程序尤其重要。

The Synchrotron Radiation Center (SRC) at 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 SRC impact a number of disciplines including condensed matter physics, atomic and molecular physics, chemistry, and materials science and engineering, and other disciplines. SRC is a user oriented facility which accepts proposals from all qualified investigators. It supports a community of 388 users from 58 university, national, and industrial laboratories. There are 18 beamlines in operation now, six are under development, and five more are proposed. Included are two dedicated beamlines in operation, one under development and two more allocated for the Center for X-ray Lithography. An x-ray microscope using an undulator as its source is under construction. Research performed at SRC has proved extremely productive, with recent publications corresponding to 15% of the world-wide total for the same period. The responsiveness of SRC and its users to new developments is shown by the 25 recent papers on high-temperature superconductors, the first submitted in April 1987. The addition of a soft x-ray beamline, and the improvement of the 1 GeV storage ring operation for higher currents are planned. The ring improvements will provide more high energy radiation which are especially important for the x-ray lithography program.
