VACUUM NEUTRON TUBE Russian patent published in 2016 - IPC G21G4/00 

FIELD: physics.

SUBSTANCE: invention relates to a vacuum neutron tube and can be used in designing neutron generators for activation analysis of alloys and compounds. Proposed vacuum neutron tube comprises tightly sealed insulating housing (1) with a controlled three-electrode ion source, anode (4) and cathode (2) of which are saturated with hydrogen isotope, target (6, 7, 8), gas absorber (5), is equipped with an additional identical controlled three-electrode ion source and a gas absorber. Herewith target electrode (6) comprises two symmetrical targets (7, 8) saturated with same or different hydrogen isotopes and is located in the middle of the housing, on the ends of which opposite to false targets there are the controlled three-electrode ion sources.

EFFECT: longer life, expanded functional and operational capabilities of a vacuum neutron tube.
