Abstract
An elastic neutron scattering instrument, the advanced neutron diffractometer/reflectometer (AND/R), has recently been commissioned at the National Institute of Standards and Technology Center for Neutron Research. The AND/R is the centerpiece of the Cold Neutrons for Biology and Technology partnership, which is dedicated to the structural characterization of thin films and multilayers of biological interest. The instrument is capable of measuring both specular and nonspecular reflectivity, as well as crystalline or semicrystalline diffraction at wave-vector transfers up to approximately 2.20 Å(-1). A detailed description of this flexible instrument and its performance characteristics in various operating modes are given.
摘要
一种弹性中子散射仪器——先进中子衍射仪/反射仪（AND/R），最近已在美国国家标准与技术研究院中子研究中心投入使用。AND/R是生物与技术冷中子合作项目的核心设备，该项目致力于对具有生物学意义的薄膜和多层膜进行结构表征。该仪器能够测量镜面反射率和非镜面反射率，以及在波矢转移高达约2.20 Å⁻¹时的晶体或半晶体衍射。文中给出了这种灵活仪器的详细描述及其在各种运行模式下的性能特征。
