摘要：

The concept of a concentrated neutron flux shaper for neutron-capture therapy of cancer has been developed. A technique for two-stage minimization of the accompanying fast neutron flux and gamma radiation background during the formation of a delayed therapeutic neutron flux is discussed. A variant of the shaper design of epithermal neutrons based on the use of collimators directed from a part of the spherical surface along the radius to the center to concentrate the flux density of these neutrons on the irradiated object is proposed.
