Study of the Characteristics of Neutron Radiation
Abstract
According to the time mode of operation, neutron sources can be divided into two groups: continuous sources and pulsed sources. Historically, the first were continuous-action sources based on the use of the (α, n) reaction on Be nuclei. In these sources, beryllium is irradiated with alpha particles of radioactive elements such as radium, polonium and plutonium. Ease of use and stable yields over short measurement periods have led to the widespread use of these sources, despite their relatively low neutron yield. The development of accelerator technology and nuclear reactors has led to a significant increase in neutron fluxes, making it possible to significantly expand the ranges of neutron yields and energies and control the energy composition of the radiation. Pulsed radiation sources have been developed to address many economic and scientific challenges, particularly in nuclear physics and nuclear energy. Pulsed radiation sources produce short, repetitive pulses of radiation, such as photons or neutrons, and allow the study of the properties of matter using the propagation of particles at a specific energy. For example, in the case of neutrons. This helps to separate them by speed in a special tube and provides precisely defined energies for experiments. Pulsed neutron sources can consist of a powerful accelerator that directs high-energy protons at a heavy target (such as mercury or tungsten), causing a spallation reaction and releasing neutrons, which includes accelerators, pulsed reactors and boosters. Scientific research involves the analysis of the properties of materials, the study of nuclear reactions.
