摘要：
Aspects of the experimental implementation of the small-angle neutron scattering (SANS) method on a compact neutron source are considered. A scientific justification of the demand for this type of installation is formulated. A scheme for implementing the SANS method on a pulsed neutron source is proposed, which ensures the high efficiency of using a neutron beam by limiting the operating wavelength range, and, as a result, maximizing the frequency and time-averaged power/intensity of the source. The physical parameters of the key elements of the installation, such as the cold neutron moderator, the beam-chopper cascade, the collimation system, the sample unit and the wide-aperture position-sensitive detector, are described. It is shown that the small-angle scattering method can be implemented on a university-type pulsed neutron source.
