Аннотация
A device that forms a vertically diverging neutron beam is described. The device allows scanning at the angle of incidence of neutrons on a fluid surface in a reflectometer with a vertical scattering plane. Computer simulation of the former is carried out, and the beam characteristics (horizontal and vertical divergences and the neutron energy spectrum) are obtained. These characteristics are compared with experimental data. Three units are the main advantages of the former: specially fabricated input and output collimators and neutron filters. The reasons for differences in the experimental and simulated data are discussed.
