The scientific and technological basis of the Russian compact neutron source DARIA (Dedicated for Academic Research and Industrial Applications) based on a linear proton accelerator have been developed. The DARIA source is designed to create beams of thermal and cold neutrons. We discuss the strategy for developing pulsed neutron sources based on the DARIA project in three directions: (1) the multiplication of the DARIA source in terms of deep specialization of neutron facilities, (2) increasing the DARIA source power to proton energies of 30—70 MeV, and (3) developing high-flux pulsed neutron source based on a high-current, high-energy (up to 1 GeV) proton accelerator and cascade-spallation reaction.
