NEUTRON PRODUCTION PROCESS Russian patent published in 2006 - IPC G21G4/02 

FIELD: nuclear physics and applied industries.

SUBSTANCE: neutron production process depending on interaction between accelerated deuterium ions and tritium nuclei includes bombardment of composite target under operating conditions of generation by deuterium ions accelerated to energy E when deuterium ion path in target is greater than total thickness of H1 + H2 + H3 layers, with neutron flux level being continuously measured; as soon as flux reduces below minimal level, deuterium supply to ion source is shut off, tritium is fed to the latter, and target is irradiated by tritium ions at accelerating voltage equal to 0.5 + 0.05 of deuterium ion accelerating voltage level under regeneration operating conditions. Tritium is periodically supplied to ion source at intervals T = (0.1 + 0.01)Td(Id/It), where Td is target operating time up to neutron flux level reduction from rated value to minimal level; Id is mean current of deuterium ions under operating conditions; It is mean current of tritium ions for target stuffing; then tritium supply to ion source is ceased and neutrons are generated by feeding deuterium thereto; neutron flux level is measured until its increment between two sequential measurements reduces to value equal to measurement error, whereupon neutrons are generated under operating conditions.

EFFECT: ability of producing maximal neutron fluxes using tritium target at its maximal life.
