论文摘要
与Electon Roade Ring Ring Ring Ring Ring Ring Borne II II in Berlin berlin emermany,Physikalisch-Technische-Bundesanstalt(PTB)的Physikalisch-Technische-Bundesanstalt(PTB)的Physikalisch-Technische-Bundesanstalt(PTB)的四晶型单色仪(FCM)光束线的超高真空(fcm)光束线的超高真空(fcm)光束线上已安装了真空兼容的光子杂交像素检测器。该设置基于Pilatus3 100K模块。该检测器可在整个光子能量范围内使用,可在1.75至10 keV的光束线上访问。补充已经安装的真空兼容Pilatus 1M检测器,用于小角度散射(SAXS)和放牧saxs(Gisaxs),可以访问更大的散射角度。水冷模块位于Goniometer臂上,相对于传入梁的距离可将其定位在-90°至90°,距离样品约200 mm。为了执行绝对散射实验,已经研究了量子效率的线性,同质性和角度依赖性,包括其相对不确定性。此外,提出了广角X射线散射(蜡),X射线衍射(XRD)和X射线反射仪(XRR)中性能的第一个结果。
A vacuum-compatible photon-counting hybrid pixel detector has been installed in the ultra-high vacuum (UHV) reflectometer of the four-crystal monochromator (FCM) beamline of the Physikalisch-Technische Bundesanstalt (PTB) at the electron storage ring BESSY II in Berlin, Germany. The setup is based on the PILATUS3 100K module. The detector can be used in the entire photon energy range accessible at the beamline from 1.75 to 10 keV. Complementing the already installed vacuum-compatible PILATUS 1M detector used for small-angle scattering (SAXS) and grazing incidence SAXS (GISAXS), it is possible to access larger scattering angles. The water-cooled module is located on the goniometer arm and can be positioned from -90° to 90° with respect to the incoming beam at a distance of about 200 mm from the sample. To perform absolute scattering experiments the linearity, homogeneity and the angular dependence of the quantum efficiency, including their relative uncertainties, have been investigated. In addition, first results of the performance in wide-angle X-ray scattering (WAXS), X-ray diffraction (XRD) and X-ray reflectometry (XRR) are presented.
