Feasibility demonstrated theoretically

Abstract

The possibility of creating a UCN source on a periodic pulsed reactor is considered. It is shown that the implementation of the time focusing principle based on non-stationary neutron diffraction and the idea of the UCN trap pulse filling allow creating a sufficiently intense UCN source in a moderate-power pulsed reactor.
