Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The GRAINS (GRAzing Incidence Neutron Scattering) time-of-flight neutron reflectometer with a horizontal sample plane is operating at beamline 10-B of the IBR-2 reactor. The instrument is designed to study nanostructured interfaces in the solid and liquid states by measuring the specular reflection coefficient and the intensity of diffuse scattering of a beam of thermal/cold neutrons. Here, the current state of the GRAINS reflectometer is presented together with experimental examples for solid and liquid interfaces. The main focuses of the development of the instrument are emphasized.
