Boron-coated tube neutron detector with three-dimensional boron-coated structure

The invention belongs to the technical field of neutron detectors, and particularly relates to a boron-coated tube neutron detector with a three-dimensional boron-coated structure, the boron-coated tube neutron detector comprises a metal tube 1 in which a rectangular spacer 2, an annular spacer 3 and an anode wire are arranged, and boron-containing material coatings are arranged on the surfaces of the rectangular spacer 2 and the annular spacer 3 and the inner surface of the metal tube 1; the rectangular spacer 2 is used for detecting neutrons incident along the radial direction of the metal tube 1, and the annular spacer 3 is used for detecting neutrons incident along the axial direction of the metal tube 1; the boron-containing material can react with incident neutrons to generate charged particles, the anode wire and the charged particles can generate induction signals, and the induction signals can be used for reading information of the neutrons. Compared with a common boron-coated tube neutron detector,
