Abstract Ultra-cold neutron (UCN) densities have been calculated for a thin film source using realistic phonon spectra of the film material (hydrogen and deuterium). The UCN's build up to a significant density inside a cryogenic container whose walls support the thin films. The UCN's density dependence on the neutron temperature,T n, was also investigated. It was found that the density reaches a maximum value atT n≏20K. A deuterium film at low temperature (5K) andT n=30 K yields a UCN density ρ≏10−9 φ0 where φ0 is the total flux.
