An accelerator-based pulsed cold neutron source was constructed. The accelerator is a 35MeV electron linear accelerator with 1kW average beam power. The cold neutron beam intensity at a specimen is equivalent to that of a research reactor of 1014 n/cmcm2·s thermal flux in the case of the quasi-elastic neutron scattering measurements. In spite of some limitations to the universal uses, it has been demonstrated by this facility that the modest capacity accelerator-based pulsed cold neutron source is a highly efficient cold neutron source with low capital investment. Design philosophy, construction details, performance and some operational experiences are described.
