The invention belongs to the technical field of
neutron generators, and particularly relates to a vertical
neutron generator. The vertical
neutron generator comprises a D+
ion source and a straight
pipe type cooling liquid flow guide
pipe which are arranged in a movable main cabinet; the cooling liquid flow guide
pipe is perpendicular to the ground, a high-
voltage input module is arranged at the top end of the cooling liquid flow guide pipe, a target
electrode is arranged at the
tail end of the cooling liquid flow guide pipe, and the D+
ion source is located below the target
electrode. The vertical
neutron generator also comprises a straight pipe type vacuum cavity, wherein one end of the vacuum cavity is connected with the
tail end of the cooling liquid flow guide pipe in a sealed mode, the other end of the vacuum cavity is connected with the
tail end of the D+
ion source in a sealed mode, and the target
electrode is located in the vacuum cavity. The vertical
neutron generator also comprises a molecular pump unit which is used for vacuumizing the vacuum cavity; the high-
voltage input module provides high-
voltage electricity for the target electrode, the cooling liquid flow guide pipe provides cooling for the target electrode, and the D+
ion source emits D+ ion beams to the target electrode, so neutrons are generated on the target electrode. Generation of neutrons of the
neutron generator can be remotely controlled, the structure can be split, main
consumables are maintainable target pieces and ion sources, and the service life is basically not limited.
