一个新的实验站，BL - 18B，已经在光子工厂的弯曲磁体光束线上建成。分支光束线配备了一个1:1聚焦的铂涂层熔融石英弯曲圆柱镜和一个固定出口双晶单色仪。反射镜可以将x射线束聚焦到大约0.4毫米（垂直）×1.2毫米（水平）。单色仪由两种扁平晶体组成，通常是Si（111）和Ge(220)，它们并排安装在测角仪上，这两种晶体可以在不打开真空室的情况下互换。除了增加Weissenberg相机用户可用的实验时间外，BL - 18B还为时间分辨劳法提供了一个点聚焦的白光束。为了使用Weissenberg和Laue方法进行更有效的曝光，一种使用400 mm×400 mm和400 mm×800 mm大成像板的新型多用途相机正在开发中。此外，还研制了一种专用于大成像板的扫描器。对扫描仪的响应进行了测试。
A new experimental station, BL‐18B, has been constructed on a bending‐magnet beamline at the Photon Factory. The branch beamline is equipped with a Pt‐coated fused quartz bend cylindrical mirror of 1:1 focusing and a fixed‐exit double‐crystal monochromator. The mirror can focus an x‐ray beam to about 0.4 mm (vertical) ×1.2 mm (horizontal). The monochromator consists of two kinds of flat crystals, usually Si(111) and Ge(220), mounted side by side on the goniometer, and those two crystals can be interchanged without opening the vacuum chamber. In addition to increasing the experimental time available to users of the Weissenberg camera, BL‐18B provides a point focused white beam for the time‐resolved Laue method. In order to allow more effective exposures using Weissenberg and Laue methods, a new multipurpose camera using large imaging plates, 400 mm×400 mm and 400 mm×800 mm, is being developed. A special scanner for the large imaging plate has also been developed. Response of the scanner was tested and the ...
