Studying the Spatial Distribution of a Neutron Flux Using Detectors Based on Helium-3 and Boron-10

The spatial distribution of the neutron flux from the output channel of a photoneutron source is measured. The measurements are made using a moving helium counter and a position-sensitive detector based on a 10B layer. The parameters of neutron distribution are presented. The work is performed as part of preparing nuclear physics experiments and applied research using small angle scattering and diffraction.
