Reflection of neutrons from an optical grating

PDF Version Also Available for Download.

Description

Specular and off-specular neutron intensities were measured at grazing incidence from an optical grating. Thee periodicity of the grating was determined from the locations of the intensity peaks in the off-specular data. An analysis of the widths of the off-specular intensity peaks showed that the effect of the coherence length of the neutron beam on the determination of a surface length scale {approximately}30 {mu}m was negligible compared to that of the instrument resolution. Although the structure of an optical grating used in this paper is simple, it has served to illustrate the simple relationship between the off-specular data structure and ... continued below

Description

Specular and off-specular neutron intensities were measured at grazing incidence from an optical grating. Thee periodicity of the grating was determined from the locations of the intensity peaks in the off-specular data. An analysis of the widths of the off-specular intensity peaks showed that the effect of the coherence length of the neutron beam on the determination of a surface length scale {approximately}30 {mu}m was negligible compared to that of the instrument resolution. Although the structure of an optical grating used in this paper is simple, it has served to illustrate the simple relationship between the off-specular data structure and the real-space properties. For more general rough systems, a practical theoretical model will be needed to relate the off-specular data to the real-space roughness structure so that the diffusive data can be analyzed. Owing to the intrinsic complexity of diffuse scattering, the development of such a theoretical model will be a significant technical challenge, and its solution will constitute a major breakthrough in the development of the diffuse reflectivity technique for rough surface/interface characterization.
