Abstract

The invention discloses a boron film cathode of a neutron detector and a preparing method of the boron film cathode of the neutron detector. The boron film cathode of the neutron detector is detector cathode with good electrical properties and neutron sensitive performance. Conductive metal Al matrix is adopted for the cathode, and the surface of the cathode is coated with a neutron sensitive film. The neutron sensitive film comprises, by mass, 100 parts of boron powder, 15 parts to 25 parts of substance (the molecular formula of the substance is described in the instruction), 7 parts to 12 parts of curing agents and 30 parts to 40 parts of organic solvent. The boron film cathode of the neutron detector is simple in preparation, low in cost, high in adhesive force and good in uniformity, and the obtained detector is high in detection efficiency.

Description

Technical field

[0001] The invention relates to a boron film cathode of a neutron detector and a preparation method thereof. Background technique

[0002] The detection of neutrons occupies a special position in the detection technology. It is much more difficult than the detection of charged particles or gamma rays. It is mainly realized through its interaction with the nucleus to generate charged particles or gamma photons. In recent years, the advantages of boron-coated gas detectors over 3He or BF3 detectors have become prominent, and they have gradually become a major neutron detection tool. Quantitative boron-coated cathode technology is the most important thing in the manufacture of boron-coated gas detectors, which is related to the determination of the detector's performance parameters and the selection of the environment in which it is used.

[0003] Due to the late development of boron-coated detectors, there are few reports on quantitative boron-coated cathode technolo...
