Problems solved by technology

However, the detection efficiency of slow neutrons in a single-layer flat-plate ionization chamber is relatively low, and methods such as multiple stacking and slow neutron grazing incidence are required to improve the overall slow neutron detection efficiency, but this will bring a negative impact on the overall signal readout process. Very high pressure, inconvenient to realize large-area slow neutron detection

Abstract

The invention relates to a slow neutron conversion body and a slow neutron detector, and belongs to the field of slow neutron detection. The slow neutron conversion body comprises a base body, and the base body comprises a plurality of holes extending in a first direction, and insulating walls among the plurality of holes, wherein the holes are through holes. The slow neutron conversion body also comprises a boron layer which at least covers the exposed surfaces of the holes. The slow neutron conversion body and the detector can maintain higher slow neutron detection efficiency. In addition, the slow neutron conversion body and the detector can reduce the manufacturing complexity and cost of the detector, thereby achieving effective, convenient and low-cost slow neutron detection.

Description

technical field [0001] The present disclosure relates to slow neutron detection, in particular, to a slow neutron converter and a slow neutron detector with the slow neutron conversion structure. Background technique [0002] With the increasing application of slow neutron detection and imaging technology in homeland security, material monitoring, and measurement of slow neutron scattering sources, the demand for slow neutron detectors is also increasing. However, the widely used 3 He gas can no longer meet the growing demand, and different types of new slow neutron detectors have been developed to replace 3 He, including gas slow neutron detectors, scintillator slow neutron detectors, semiconductor slow neutron detectors, etc. [0003] For a slow neutron detector, the slow neutron converter is an important structure. Slow neutrons themselves have no charge, except for a few slow neutron sensitive nuclides such as 6 Li, 10 B, Gd, etc., the reaction cross sections of slo...
