FIELD: nuclear physics; multiplying neutrons for building subcritical nuclear reactors.
SUBSTANCE: proposed multistage neutron multiplier has a number of multiplication stages abutting against each other. Each stage has coaxially arranged disks of different thickness abutting against each other. Disks are assembled of active material, neutron moderators of two types, and neutron absorber. They are alternating in stage so as to ensure unidirectional movement of neutrons and their multiplication.
EFFECT: enhanced neutron multiplication factor.
