Description
The Neutron Technology Development Station (NTDS) at the China Spallation Neutron Source (CSNS) is a testing beamline dedicated to advancing neutron instrumentation and methodologies. This paper presents the design and application of its reflectivity measurement terminal, a versatile platform developed for high-precision neutron supermirror reflectometry. The terminal is equipped with multiple slits, detectors, a multi-dimensional sample stage, and other components, enabling detailed characterization of neutron guides, multilayer supermirror films, and interfacial structures. Current progress includes successful commissioning of the terminal with beam and preliminary results obtained on supermirror samples, which validate the reliability of reflectivity measurements. Expert feedback and suggestions on further expanding the terminal's capabilities are highly appreciated.
