FIELD: physics.
SUBSTANCE: invention utilises the difference in initial kinetic energies of mono- and diatomic hydrogen ions to separate monoatomic ions and obtain an ion beam with high content of the monoatomic component. To this end, an ion source with electron circulation includes additional electrodes - reflector and collector, which form an electrostatic potential barrier which reflects diatomic ions but not monoatomic ions.
EFFECT: invention enables to increase content of the monoatomic component in an ion beam, which can be used to prolong the life and increase reliability of pulsed neutron generators.
