In Petersburg Nuclear Physics Institute (PNPI) a project of the source of ultracold neutrons (UCN) based on superfluid helium for the WWR-M reactor has been developed. It must provide UCN density 2-3 orders of magnitude higher than existing sources. For the new source we propose an experiment on search for neutron–antineutron oscillations based on the storage of ultracold neutrons in a material trap. The sensitivity of the experiment mostly depends on the trap size and the amount of UCN in it. The results of simulations of the designed experimental scheme show that the sensitivity can be increased by ~ 10–40 times compared to sensitivity of previous experiment depending on the model of neutron reflection from walls.
