新XAFS专用束线1W1B由储存环中7周期WIGGLER 1W1引出，为聚焦单色光束线。 该束线光强比4W1B提高了一个量级以上，2008年实验站建立了19元半导体阵列探测器，大大提高了痕量元素的测试能力。 该束线一直稳定运行至今，2014年实现在专用和兼用两种模式下运行开放。 有效机时利用率达到98％以上，每年完成的用户课题数为BSRF接受的总课题数的20％－30％，每年相关工作发表文章约为几百篇。 图1 XAFS实验站. 二、研究范围. 由于XAFS适合于所有样品的物理 …
An integrated and versatile QXAFS system for general XAFS …
Nov 1, 2022 · Based on the beamline 1W1B, the top rotation speed of current monochromator is only 0.167°/s, that limits a time resolution of about 5.2 s at Pt L 3-edge EXAFS spectrum. Actually, our QXAFS system will reduce the time further if the motor can go faster.
1W1B-XAFS 光束线是在北京同步辐射装置建造的一条 XAFS 专用光束线,于 2003 年初完成了调试并投入运行。 1W1B-XAFS 束线是一条聚焦单色光束线,由一个七极永磁 WIGGLER,1W1 引出,束线主要光学系统是在距光源 21.99 米处放置准直镜;距光源 24.11m 处安装双晶单色器, 其下游距光源 25.82m 处安装超环面镜。束线从前端引出后, 首先经过准直镜, 用以改善出射光的垂直发散度, 从而提高系统能量分辨率;出射光经由双晶单色器单色化后,最后由超环面镜做水平和垂直聚焦到样 …
In this paper, we will introduce the QXAFS system built at 1W1B, a general hard X-ray XAFS beamline at Beijing Synchrotron Radiation Facility (BSRF).
