Abstract

The suite of neutron powder diffractometers at Oak Ridge National Laboratory (ORNL) utilizes the distinct characteristics of the Spallation Neutron Source and High Flux Isotope Reactor to enable the measurements of powder samples over an unparalleled regime at a single laboratory. Full refinements over large Q ranges, total scattering methods, fast measurements under changing conditions, and a wide array of sample environments are available. This article provides a brief overview of each powder instrument at ORNL and details the complementarity across the suite. Future directions for the powder suite, including upgrades and new instruments, are also discussed.

摘要

橡树岭国家实验室（ORNL）的中子粉末衍射仪套件利用散裂中子源和高通量同位素反应堆的独特特性，能够在单一实验室对粉末样品进行前所未有的测量。可进行大Q范围的全精修、总散射方法、在变化条件下的快速测量以及各种各样的样品环境。本文简要概述了ORNL的每台粉末仪器，并详细介绍了整个套件的互补性。还讨论了粉末套件的未来发展方向，包括升级和新仪器。
