GENERATOR OF LABELED NEUTRONS Russian patent published in 2004 - IPC

FIELD: formation of beams of labeled neutrons. SUBSTANCE: invention specifically refers to unsoldered neutron generators and can find use in systems of nondestructive remote analysis of complex chemical substances and in nuclear- physical plants where recording of high-intensity fluxes of charged particles is required. Generator of labeled neutrons presents sealed body housing ion source, source of gaseous deuterium and tritium, system of accelerating and focusing electrodes, tritium target and scintillators of alpha detector. Body has windows for optical communication of scintillators with photomultipliers of alpha detector arranged on outside of body of generator. Characteristic feature of invention lies in manufacture of alpha detector with many channels, in arrangement of scintillators in the form of matrix. Crystal of yttrium aluminate activated by cerium (YA1O₃(Ce)-YAP(Ce)), in addition scintillator is provided with absorber of deuterium scattered in target. EFFECT: provision for long-term preservation of static vacuum in generator of labeled neutrons, prolonged service life of generator, securing of accurate time marking of emission of neutrons. 5 cl, 3 dwg
