Abstract
Cold neutron source with liquid deuterium moderator for the HEC-2 channel of PIK reactor is considered. Two variants of moderator chamber location in the reactor reflector are compared. It is shown, that the energy release in the chamber strongly increases when it approaches the reactor core. At the same time, the brilliance of the source increases only moderately. The great influence of the displacer in the liquid deuterium chamber of large volume is demonstrated. Cold neutron source brilliance for two positions of the chamber in the reflector is calculated as well as energy release in the chamber and supplying tubes. The cold neutron source with total heat release in the in-pile constructions about 10 kW can reach the record brilliance compared to brilliance of other cold neutron sources in the world.
