Abstract
In the production of ultracold neutrons (UCN) by scattering cold neutr ons in superfluid He-4 or cold solid D-2 (''superthermal'' processes), the UCN production rate is proportional to the spatial density of col d neutrons in the material. For a superthermal source fed from a cold neutron guide, we show that the rate of UCN production can be increase d by up to a factor of about 2.3 for realistic substances by enclosing the source in a cavity made of a material with a high cold neutron al bedo.
