VACUUM NEUTRON TUBE Russian patent published in 2005 - IPC

FIELD: neutron engineering; production of devices for generation of a fast neutrons stream.

SUBSTANCE: the invention is pertaining to production of devices for generation of a fast neutrons stream, in particular, to production of vacuum neutron tubes. The invention presents the vacuum neutron tube, which has been made in the form of a hermetic body with located inside it a source of ions representing a system "an electron projector - an emitting ions anode" and a neutron-forming target. The internal space is divided into two sealed volumes by a diaphragm with a hole, in which there is a hermetically fixed anode facing the target. In one of the volumes there is a cathode of the electron gun, and in the other - the target is placed. The technical result of the invention is simplification of the vacuum neutron tube design, increased its effectiveness due to an increased emissive capacity of the cathode.

EFFECT: the invention ensures simplification of the vacuum neutron tube design, its increased effectiveness and emissive capacity of the cathode.
