摘　　要：电子束经过储存环弯转磁铁发生偏转时,产生总功率～435kW的同步辐射光,其中仅有一小部分被引入光束线、实验站,其余须在储存环中被光子吸收器吸收处理,并准直引出光束。本文对上海光源(SSRF)储存环同步辐射光的处理方法进行了讨论,并介绍了光子吸收器的布局、结构、性能及运行状况。There are 40 bending magnets in the 432-m storage ring of the Shanghai Synchrotron Radiation Facility （SSRF）. A total power of 435 kW is delivered by synchrotron radiations when the electron beams pass through the bending magnets. Only a small part of the radiation is extracted into the beamlines and the experiment stations, and the rest has to be absorbed and transferred out of the storage ring. Photon absorbers are placed at different points of the storage ring to intercept the unused synchrotron radiation and align the extracted light. In this paper, the radiation treatment method is discussed and layout of the absorbers is described in detail. The structure of the absorbers, the manufacture and assembly, and performance of the absorbers are introduced.
