Abstract

We report the design and construction of a novel soft x-ray diffractometer installed at Diamond Light Source. The beamline endstation RASOR is constructed for general users and designed primarily for the study of single crystal diffraction and thin film reflectivity. The instrument is comprised of a limited three circle (theta, 2theta, and chi) diffractometer with an additional removable rotation (phi) stage. It is equipped with a liquid helium cryostat, and post-scatter polarization analysis. Motorized motions are provided for the precise positioning of the sample onto the diffractometer center of rotation, and for positioning the center of rotation onto the x-ray beam. The functions of the instrument have been tested at Diamond Light Source, and initial test measurements are provided, demonstrating the potential of the instrument.

摘要

我们报告了安装在钻石光源（Diamond Light Source）的新型软X射线衍射仪的设计与建造情况。光束线终端站RASOR是为普通用户建造的，主要设计用于单晶衍射和薄膜反射率研究。该仪器由一个有限的三圆（θ、2θ和χ）衍射仪组成，并带有一个额外的可移动旋转（φ）台。它配备了液氦低温恒温器和散射后偏振分析装置。提供了电动运动装置，用于将样品精确地定位到衍射仪的旋转中心，并将旋转中心定位到X射线上。该仪器的功能已在钻石光源进行了测试，并给出了初步测试测量结果，证明了该仪器的潜力。
