  • Patent number: 11090686
    Abstract: The present application relates to a method for coating boron, to a boron-containing resin solution, to a boron-coated thermal neutron converter obtained by the method for coating boron, and further to a thermal neutron detector comprising the boron-coated thermal neutron converter. The method for coating boron as provided in the application is applicable for various substrates and has small restrictions on substrate shapes, particularly for substrates having complex surface structures and high aspect ratios.
    Type: Grant

  • Patent number: 10732306
    Abstract: A slow neutron detection device is disclosed, comprising: a first slow neutron converter and a second slow neutron converter, and a readout electrode wire set and cathode wire sets arranged between the first slow neutron converter and the second slow neutron converter. By arranging a readout circuit between the two slow neutron converters, an electron drift distance is reduced by half without changing a dimension of the detection device, and an average over-threshold probability of a signal is increased.

  • Patent number: 10126440
    Abstract: The present application, pertaining to the field of slow neutron detection, relates to a slow neutron converter and a slow neutron detector. The slow neutron converter includes a substrate, the substrate including a plurality of holes extending along a first direction and insulating walls between the plurality of holes, wherein the plurality of holes are through holes. The slow neutron converter further includes a boron layer at least covering an exposed surface of the plurality of holes. The slow neutron converter and the slow neutron detector having the slow neutron converter according to the present disclosure are capable of maintaining a high slow neutron detection efficiency. In addition, the manufacturing complexity and manufacturing cost of the detector are reduced, and thus the effective, convenient and low-cost slow neutron detection is achieved.
