Abstract

Accurate measurement of the transverse beam-profile is critical to analyzing the performance of the electron storage ring light sources. In this paper, a two-dimensional interferometer using the spatial coherence of the synchrotron radiation is developed to measure the transverse beam-profile of Hefei Light Source-II (HLS-II). On the B7 beamline, the transverse beam-profile of this light source point was measured by the interference fringes of Synchrotron Radiation (SR) with wavelength of 500 nm. Under the normal top-off operation mode of HLS-II, the horizontal and vertical beam sizes measured by the interferometer are $291.9\pm 1.6\ \mu\mathrm{m}$ and $241.3\pm 0.9\ \mu\mathrm{m}$, respectively. At the same time, the effect of beam intensity on the transverse beam-profile was also investigated. The interferometer measurement system we designed satisfies the real-time online monitoring of the transverse beam-profile in the top-off operation mode of HLS-II.

用于测量 HLS-II 横向光束轮廓的二维可见同步辐射干涉仪

精确测量横向光束轮廓对于分析电子存储环光源的性能至关重要。本文开发了一种利用同步辐射空间相干性的二维干涉仪，用于测量合肥光源-II（HLS-II）的横向光束轮廓。在 B7 光束线上，利用波长为 500 nm 的同步辐射（SR）干涉条纹测量了该光源点的横向光束轮廓。在HLS-II的正常顶关工作模式下，干涉仪测得的横向和纵向光束尺寸分别为291.9\pm 1.6\mu\mathrm{m}$和241.3\pm 0.9\mu\mathrm{m}$。同时，我们还研究了光束强度对横向光束轮廓的影响。我们设计的干涉仪测量系统可以满足在HLS-II的顶关运行模式下对横向光束轮廓的实时在线监测。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
