Design of a Prototype for the Radio-Frequency Quadrupole Sections of the DARIA Compact Neutron Source

The design of the DARIA compact neutron source based on a linear resonant proton accelerator is aimed at creating a serial installation capable of providing the Russian scientific community with pulsed neutron beams with intensities comparable to those of research nuclear reactors. The absence of fissile material makes it possible to significantly reduce the radiation-safety requirements for such installations and, consequently, to place them at the site of leading scientific centers and universities that train specialists in the field of neutron physics. Under a grant from the Ministry of Science and Higher Education of the Russian Federation, key elements of the installation are being developed. The design and sequence of manufacturing for a full-scale model of an accelerator section with radio-frequency quadrupole focusing and a cavity with a drift-tube linac are presented.
