A study of characteristics of Helium-3 (He-3) proportional counters in order to design electronic circuits for neutron detection

This study aims to research and develop function circuits, electronic blocks, programming software for He-3 proportional counters using commonly in neutron detection. Results are compared with those of a neutron dosimeter available in Institute for Nuclear Science and Technology (INST). Although the method has been known for a long time on the world, it is newly used in Vietnam. If the study is applied in reality, neutron dosimeters will be manufactured with acceptable price, high quality, and easy maintenance which are suitable with domestic demands. It contributes to nuclear safety and economy-society development. (author)
