NEUTRON PRODUCTION METHOD Russian patent published in 2006 - IPC G21G4/02 H05H6/00 

FIELD: neutron entrapping therapy.

SUBSTANCE: proposed method includes irradiation of stream of solid active-material rarefied particles moved perpendicular to mentioned beam by accelerated charged particles, such as protons, to conduct neutron-producing reaction in mentioned particles. Active material particles can be moved using gravitational forces or pressure difference between volumes of active-material particles being fed and received to form particle suspension in rarefied light gas. Size, volume concentration, and thickness of active particle stream are chosen so as to optimize nuclear reaction conditions. Heat energy released in the process is uniformly distributed throughout entire volume of active particle stream in working zone thereby simplifying target cooling. Neutron-producing assemblies implementing this method are described in invention specification.

EFFECT: facilitated procedure, reduced cost of neutron production for medicine.
