Abstract: High-flux neutron sources are relevant to testing materials for thermonuclear facilities and hadron colliders, treating malignant tumors with boron neutron capture therapy, and other applications. An accelerator-based neutron source was proposed and implemented at the Budker Institute of Nuclear Physics in Novosibirsk, Russia. It comprises an originally designed tandem accelerator, a solid lithium target, and a neutron beam shaping assembly. The neutron source has been found capable of producing high neutron fluxes in different energy ranges, from thermal to fast. It is applicable to a wide range of research tasks, including the characterization of neutron detectors, intended for fusion studies, in-depth investigation of the promising 11B(p, α)αα neutronless fusion reaction, etc.
