上海光源单色光荧光靶的升级改造

Upgrading for Monochromatic Fluorescence Screen BPMat SSRF

光束位置探测器是同步辐射装置上的"眼睛",其中荧光靶探测器是最为直观和方便使用的一种,对于光束线的调试有着重要的作用。论文对上海光源一期研制的单色光荧光靶探测器在使用过程中存在的问题,进行了较为全面的分析总结,提出了新的设计方案,改进了单色光荧光靶的结构,压缩了该装置的体积,并且采用YAG晶体做荧光靶材,提高了探测灵敏度。改造后的单色光荧光靶探测器已经成功使用在蛋白设施五线六站新的光束线站上,取得了良好的效果。

Beam Position Monitor（ BPM） is an eye of synchrotron radiation facility,Fluorescence Screen（ FS）is one of the most intuitive and convenient detector. It has a very important effect to beam- line debugging. In this work,according to the defects which occurs by monochromatic fluorescence screen BPM working in SSRF Phase1,we analysed exhaustively and proposed a new design,improved the structure of Monochromatic fluorescence screen BPM,compressed the size of the detector,and taking the YAG crystal as the material of fluorescence screen. This increased the detection sensitivity. The improved Monochromatic fluorescence screen BPM is working in SSRF new lines now,and it has a positive effect and good result.
