合肥国家同步辐射光源

Hefei National Synchrotron Radiation Source

光，或者更普遍地说电磁辐射，是人类观察和研究自然界所不可缺少的工具．同步辐射这种具有许多优异特性的电磁辐射更不例外，虽然发现的时间不长，却已广泛应用于许多科学和技术领域，推动了科学技术的长足进步．我国于１９７８年开始筹建自己的同步辐射光源──合肥国家同步辐射光源．它由一台 ８００ＭｅＶ电子储存环和一台 ２００ＭｅＶ直线加速器注入器组成．它于 １９８４年 １１ 月动工，１９８９年 ４月建成出光，１９９１年６月调试结果，其主要性能指标已达到国际先进水平．本文重点介绍合肥国家同步辐射光源，同时还阐述同步辐射和同步辐射光源的一些基本问题．

The hefei national synchrotron radiation source is China's first dedicated synchrotron radiation source. It consists of an 800 MeV storage ring and a 200 MeV linac injector. Construction started in November, 1984 and was completed in April, 1989 The stored beam current reached 267 mA in June, 1991 The routine operation beam current is more than 200 mA. The storage ring can accommodate more than 50 beamlines, including bra- nches. Up till now, five beamlines and five user's stations have been built. These stations will be used in research on photoelectron spectroscopy, time-resolved spectroscopy, photo- chemistry, soft X-ray microscopy and soft X-ray lithography.
