国家同步辐射实验室正在设计和制造一台6T单周期超导摆器(Wiggler)把合肥同步辐射光源的可用范围延伸到X射线,满足部分X射线用户的要求.利用扭摆器光源装备四条光束线.分别用于X射线吸收精细结构(XAFS),生物大分子晶体多波长反常衍射(MAD),X射线深度光刻(LIGA)和高分辩X 射线衍射(HRXD)的研究.该文介绍了合肥扭摆器光源的主要特性、光束线前端保护、分束系统和各条光束线的设计参数及结构方案.
The National Synchrotron Radiation Facility is designing and manufacturing a 6T single-cycle Wiggler that extends the available range of Hefei synchrotron radiation sources to X-rays to meet the needs of some X-ray users. Equipped with four beamlines using a wobbler light source. They were used to study XAFS, MAD, LIGA and HRXD respectively. This paper introduces the main features of Hefei twist light source, the front-end protection of the beam line, the design parameters and the structure scheme of the beam splitting system and each beam line.
