Description

technical field [0001] The invention belongs to the field of physics, and in particular relates to a small-scale high-current neutron source device based on a linear accelerator. Background technique [0002] Because neutrons have no charge, so they have strong penetrating ability, and neutrons have a magnetic moment, so neutrons are very important tools in material research and nuclear structure research, especially the demand for high-flux neutrons is increasing Important. With the demands of scientific research and emerging cancer treatment fields, the construction of high-flux small-scale neutron sources has become an important strategic facility for basic research and new material research and development. The neutron sources currently in use are mainly derived from reactors. For neutrons produced by neutrons or isotopes, reactor neutron sources cannot be widely used due to safety restrictions, and neutron yields produced by isotope neutron sources are low, resulting in...

[0002] Because neutrons have no charge, so they have strong penetrating ability, and neutrons have a magnetic moment, so neutrons are very important tools in material research and nuclear structure research, especially the demand for high-flux neutrons is increasing Important. With the demands of scientific research and emerging cancer treatment fields, the construction of high-flux small-scale neutron sources has become an important strategic facility for basic research and new material research and development. The neutron sources currently in use are mainly derived from reactors. For neutrons produced by neutrons or isotopes, reactor neutron sources cannot be widely used due to safety restrictions, and neutron yields produced by isotope neutron sources are low, resulting in poor use effects; therefore, providing a high-safety A small-scale intense neutron source device based on a linear accelerator that is economical, practical, and easy to popularize
